Big Data means big hardware, and the less of it we can use to do the job properly, the better the bottom line. Apache Kafka makes up the core of our data pipelines at many organizations, including LinkedIn, and we are on a perpetual quest to squeeze as much as we can out of our systems, from Zookeeper, to the brokers, to the various client applications. This means we need to know how well the system is running, and only then can we start turning the knobs to optimize it. In this talk, we will explore how best to monitor Kafka and its clients to assure they are working well. Then we will dive into how to get the best performance from Kafka, including how to pick hardware and the effect of a variety of configurations in both the broker and clients. We’ll also talk about setting up Kafka for no data loss.
Presentation at Strata Data Conference 2018, New York
The controller is the brain of Apache Kafka. A big part of what the controller does is to maintain the consistency of the replicas and determine which replica can be used to serve the clients, especially during individual broker failure.
Jun Rao outlines the main data flow in the controller—in particular, when a broker fails, how the controller automatically promotes another replica as the leader to serve the clients, and when a broker is started, how the controller resumes the replication pipeline in the restarted broker.
Jun then describes recent improvements to the controller that allow it to handle certain edge cases correctly and increase its performance, which allows for more partitions in a Kafka cluster.
Kafka's basic terminologies, its architecture, its protocol and how it works.
Kafka at scale, its caveats, guarantees and use cases offered by it.
How we use it @ZaprMediaLabs.
A brief introduction to Apache Kafka and describe its usage as a platform for streaming data. It will introduce some of the newer components of Kafka that will help make this possible, including Kafka Connect, a framework for capturing continuous data streams, and Kafka Streams, a lightweight stream processing library.
Apache Kafka becoming the message bus to transfer huge volumes of data from various sources into Hadoop.
It's also enabling many real-time system frameworks and use cases.
Managing and building clients around Apache Kafka can be challenging. In this talk, we will go through the best practices in deploying Apache Kafka
in production. How to Secure a Kafka Cluster, How to pick topic-partitions and upgrading to newer versions. Migrating to new Kafka Producer and Consumer API.
Also talk about the best practices involved in running a producer/consumer.
In Kafka 0.9 release, we’ve added SSL wire encryption, SASL/Kerberos for user authentication, and pluggable authorization. Now Kafka allows authentication of users, access control on who can read and write to a Kafka topic. Apache Ranger also uses pluggable authorization mechanism to centralize security for Kafka and other Hadoop ecosystem projects.
We will showcase open sourced Kafka REST API and an Admin UI that will help users in creating topics, re-assign partitions, Issuing
Kafka ACLs and monitoring Consumer offsets.
Performance Tuning RocksDB for Kafka Streams' State Stores (Dhruba Borthakur,...confluent
RocksDB is the default state store for Kafka Streams. In this talk, we will discuss how to improve single node performance of the state store by tuning RocksDB and how to efficiently identify issues in the setup. We start with a short description of the RocksDB architecture. We discuss how Kafka Streams restores the state stores from Kafka by leveraging RocksDB features for bulk loading of data. We give examples of hand-tuning the RocksDB state stores based on Kafka Streams metrics and RocksDB’s metrics. At the end, we dive into a few RocksDB command line utilities that allow you to debug your setup and dump data from a state store. We illustrate the usage of the utilities with a few real-life use cases. The key takeaway from the session is the ability to understand the internal details of the default state store in Kafka Streams so that engineers can fine-tune their performance for different varieties of workloads and operate the state stores in a more robust manner.

In the last few years, Apache Kafka has been used extensively in enterprises for real-time data collecting, delivering, and processing. In this presentation, Jun Rao, Co-founder, Confluent, gives a deep dive on some of the key internals that help make Kafka popular.
- Companies like LinkedIn are now sending more than 1 trillion messages per day to Kafka. Learn about the underlying design in Kafka that leads to such high throughput.
- Many companies (e.g., financial institutions) are now storing mission critical data in Kafka. Learn how Kafka supports high availability and durability through its built-in replication mechanism.
- One common use case of Kafka is for propagating updatable database records. Learn how a unique feature called compaction in Apache Kafka is designed to solve this kind of problem more naturally.
Kafka Tutorial - Introduction to Apache Kafka (Part 1)Jean-Paul Azar
Why is Kafka so fast? Why is Kafka so popular? Why Kafka? This slide deck is a tutorial for the Kafka streaming platform. This slide deck covers Kafka Architecture with some small examples from the command line. Then we expand on this with a multi-server example to demonstrate failover of brokers as well as consumers. Then it goes through some simple Java client examples for a Kafka Producer and a Kafka Consumer. We have also expanded on the Kafka design section and added references. The tutorial covers Avro and the Schema Registry as well as advance Kafka Producers.

Producer Performance Tuning for Apache KafkaJiangjie Qin
Kafka is well known for high throughput ingestion. However, to get the best latency characteristics without compromising on throughput and durability, we need to tune Kafka. In this talk, we share our experiences to achieve the optimal combination of latency, throughput and durability for different scenarios.

Apache Kafka를 이용하여 이미지 데이터를 얼마나 빠르게(with low latency) 전달 가능한지 성능 테스트.
최종 목적은 AI(ML/DL) 모델의 입력으로 대량의 실시간 영상/이미지 데이터를 전달하는 메세지 큐로 사용하기 위하여, Drone/제조공정 등의 장비에서 전송된 이미지를 얼마나 빨리 AI Model로 전달 할 수 있는지 확인하기 위함.
그래서 Kafka에서 이미지를 전송하는 간단한 테스트를 진행하였고,
이 과정에서 latency를 얼마나 줄여주는지를 확인해 보았다.(HTTP 프로토콜/Socket과 비교하여)
[현재 까지 결론]
- Apache Kafka는 대량의 요청 처리를 위한 throughtput에 최적화 된 솔루션임.
- 현재는 producer의 몇가지 옵션만 조정하여 테스트한 결과이므로,
- 잠정적인 결과이지만, kafka의 latency를 향상을 위해서는 많은 시도가 필요할 것 같음.
- 즉, 단일 요청의 latency는 확실히 느리지만,
- 대량의 처리를 기준으로 평균 latency를 비교하면 평균적인 latency는 많이 낮아짐.

ksqlDB is a stream processing SQL engine, which allows stream processing on top of Apache Kafka. ksqlDB is based on Kafka Stream and provides capabilities for consuming messages from Kafka, analysing these messages in near-realtime with a SQL like language and produce results again to a Kafka topic. By that, no single line of Java code has to be written and you can reuse your SQL knowhow. This lowers the bar for starting with stream processing significantly.
ksqlDB offers powerful capabilities of stream processing, such as joins, aggregations, time windows and support for event time. In this talk I will present how KSQL integrates with the Kafka ecosystem and demonstrate how easy it is to implement a solution using ksqlDB for most part. This will be done in a live demo on a fictitious IoT sample.
Like many other messaging systems, Kafka has put limit on the maximum message size. User will fail to produce a message if it is too large. This limit makes a lot of sense and people usually send to Kafka a reference link which refers to a large message stored somewhere else. However, in some scenarios, it would be good to be able to send messages through Kafka without external storage. At LinkedIn, we have a few use cases that can benefit from such feature. This talk covers our solution to send large message through Kafka without additional storage.
Kafka Tiered Storage separates compute and data storage in two independently scalable layers. Uber's Kafka Improvement Proposal (KIP) #405 describes two-tiered storage, which is a major step towards cloud-native Kafka. It stores the most recent data locally and offloads older data to a remote storage service. Operationally, the benefit is faster routine cluster maintenance activities. In Linkedin, Kafka tiered storage is strongly desired to reduce the cost of running Kafka in the Azure cloud environment. As KIP-405 does not dictate the implementation of remote storage substrate, Linkedin's choice for tiering Kafka in Azure deployments is the Azure Blob Service. This presentation will begin with the motivation behind Linkedin efforts to adopt Kafka Tiered Storage. Next, the architecture of KIP-405 will be discussed. Finally, the Remote Storage Manager for Azure Blobs, which is a work-in-progress, will be presented.

Kafka is a high-throughput, fault-tolerant, scalable platform for building high-volume near-real-time data pipelines. This presentation is about tuning Kafka pipelines for high-performance.
Select configuration parameters and deployment topologies essential to achieve higher throughput and low latency across the pipeline are discussed. Lessons learned in troubleshooting and optimizing a truly global data pipeline that replicates 100GB data under 25 minutes is discussed.
Kafka Streams is a new stream processing library natively integrated with Kafka. It has a very low barrier to entry, easy operationalization, and a natural DSL for writing stream processing applications. As such it is the most convenient yet scalable option to analyze, transform, or otherwise process data that is backed by Kafka. We will provide the audience with an overview of Kafka Streams including its design and API, typical use cases, code examples, and an outlook of its upcoming roadmap. We will also compare Kafka Streams' light-weight library approach with heavier, framework-based tools such as Spark Streaming or Storm, which require you to understand and operate a whole different infrastructure for processing real-time data in Kafka.
Running Apache Kafka in production is only the first step in the Kafka operations journey. Professional Kafka users are ready to handle all possible disasters - because for most businesses having a disaster recovery plan is not optional.
In this session, we’ll discuss disaster scenarios that can take down entire Kafka clusters and share advice on how to plan, prepare and handle these events. This is a technical session full of best practices - we want to make sure you are ready to handle the worst mayhem that nature and auditors can cause.

Flink Forward San Francisco 2022.
Resource Elasticity is a frequently requested feature in Apache Flink: Users want to be able to easily adjust their clusters to changing workloads for resource efficiency and cost saving reasons. In Flink 1.13, the initial implementation of Reactive Mode was introduced, later releases added more improvements to make the feature production ready. In this talk, we’ll explain scenarios to deploy Reactive Mode to various environments to achieve autoscaling and resource elasticity. We’ll discuss the constraints to consider when planning to use this feature, and also potential improvements from the Flink roadmap. For those interested in the internals of Flink, we’ll also briefly explain how the feature is implemented, and if time permits, conclude with a short demo.

URP? Excuse You! The Three Kafka Metrics You Need to KnowTodd Palino
What do you really know about how to monitor a Kafka cluster for problems? Is your most reliable monitoring your users telling you there’s something broken? Are you capturing more metrics than the actual data being produced? Sure, we all know how to monitor disk and network, but when it comes to the state of the brokers, many of us are still unsure of which metrics we should be watching, and what their patterns mean for the state of the cluster. Kafka has hundreds of measurements, from the high-level numbers that are often meaningless to the per-partition metrics that stack up by the thousands as our data grows.
We will thoroughly explore three key monitoring concepts in the broker, that will leave you an expert in identifying problems with the least amount of pain:
Under-replicated Partitions: The mother of all metrics
Request Latencies: Why your users complain
Thread pool utilization: How could 80% be a problem?
We will also discuss the necessity of availability monitoring and how to use it to get a true picture of what your users see, before they come beating down your door!
Apache Kafka lies at the heart of the largest data pipelines, handling trillions of messages and petabytes of data every day. Learn the right approach for getting the most out of Kafka from the experts at LinkedIn and Confluent. Todd Palino and Gwen Shapira demonstrate how to monitor, optimize, and troubleshoot performance of your data pipelines—from producer to consumer, development to production—as they explore some of the common problems that Kafka developers and administrators encounter when they take Apache Kafka from a proof of concept to production usage. Too often, systems are overprovisioned and underutilized and still have trouble meeting reasonable performance agreements.
Topics include:
- What latencies and throughputs you should expect from Kafka
- How to select hardware and size components
- What you should be monitoring
- Design patterns and antipatterns for client applications
- How to go about diagnosing performance bottlenecks
- Which configurations to examine and which ones to avoid
This presentation was given at the ApacheCon 2015 Kafka Meetup.

Challenges of a multi tenant kafka serviceThomas Alex
Presentation at Seattle Apache Kafka Meetup Apr 18, 2017
Abstract: Microsoft has extensive deployments of Kafka supporting large scale data streaming. This talk will introduce the challenges in building a multi-tenant system for the enterprise, and discuss the design approach we have taken.
Speaker: Thomas Alex, Principal Program Manager, Microsoft
Thomas Alex is a Program Manager in the Shared Data team at Microsoft, and has worked on many aspects of big data: data ingestion, data distribution, master data management, orchestration and ETL pipeline management, data virtualization, in-memory databases, business intelligence, and reporting.
Multi tier, multi-tenant, multi-problem kafkaTodd Palino
At LinkedIn, the Kafka infrastructure is run as a service: the Streaming team develops and deploys Kafka, but is not the producer or consumer of the data that flows through it. With multiple datacenters, and numerous applications sharing these clusters, we have developed an architecture with multiple pipelines and multiple tiers. Most days, this works out well, but it has led to many interesting problems. Over the years we have worked to develop a number of solutions, most of them open source, to make it possible for us to reliably handle over a trillion messages a day.
Kafka at Scale: Multi-Tier ArchitecturesTodd Palino
This is a talk given at ApacheCon 2015
If data is the lifeblood of high technology, Apache Kafka is the circulatory system in use at LinkedIn. It is used for moving every type of data around between systems, and it touches virtually every server, every day. This can only be accomplished with multiple Kafka clusters, installed at several sites, and they must all work together to assure no message loss, and almost no message duplication. In this presentation, we will discuss the architectural choices behind how the clusters are deployed, and the tools and processes that have been developed to manage them. Todd Palino will also discuss some of the challenges of running Kafka at this scale, and how they are being addressed both operationally and in the Kafka development community.
Note - there are a significant amount of slide notes on each slide that goes into detail. Please make sure to check out the downloaded file to get the full content!
Presented at Kafka Summit 2016
Operating out of multiple datacenters is a large part of most disaster recovery plans, but it brings extra complications to our data pipelines. Instead of having a straight path from front to back, it now has forks and dead ends and odd little use cases that don’t match up with a perfect view of the world. This talk will focus on how to best utilize Apache Kafka in this world, including basic architectures for multi-datacenter and multi-tier clusters. We will also touch on how to assure messages make it from producer to consumer, and how to monitor the entire ecosystem.

Leading Without Managing: Becoming an SRE Technical LeaderTodd Palino
Increasingly, technical organizations are developing career paths to build and recognize leaders outside of the traditional management roles. But what should an SRE who wants to be a leader be focusing on? Through the eyes of an engineer who reinvented his career in one of the largest SRE organizations, we will examine what technical leadership looks like, and how an individual can help guide the strategic path of a team, department, or company without taking on the role of a people manager. You'll pick up tactical work that you can start immediately to set yourself up for success, and some pointers to be able to identify the opportunities when they show up.
From Operations to Site Reliability in Five Easy StepsTodd Palino
Across industries, modern operations teams have noted the emergence of a new role: the Site Reliability Engineer (SRE): an IT craftsperson who fuses software engineering and operations best practices to enable highly reliable software systems. Once the domain of technology giants, this discipline is both applicable and important for any organization looking to differentiate itself in a world increasingly defined by software.
In this session, Todd Palino from LinkedIn explores how SRE evolves from Operations by taking the ‘lid-off’ SRE at LinkedIn. He’ll describe how by crafting automation, problem solving, and building a partnership with software engineering teams, companies can build a high-trust and inclusive team culture that is needed to drive continuous improvement — and importantly, have lots of fun doing it!
Code Yellow: Helping Operations Top-Heavy Teams the Smart WayTodd Palino
All engineering teams run into trouble from time to time. Alert fatigue, caused by technical debt or a failure to plan for growth, can quickly burn out SREs, overloading both development and operations with reactive work. Layer in the potential for communication problems between teams, and we can find ourselves in a place so troublesome we cannot easily see a path out. At times like this, our natural instinct as reliability engineers is to double down and fight through the issues. Often, however, we need to step back, assess the situation, and ask for help to put the team back on the road to success.
We will look at the process for Code Yellow, the term we use for this process of “righting the ship”, and discuss how to identify teams that are struggling. Through a look at three separate experiences, we will examine some of the root causes, what steps were taken, and how the engineering organization as a whole supports the process.
Monitoring services is easy, right? Set up a notification that goes out when a certain number increases past a certain threshold to let you know that there’s a problem. But if that’s the case, why are so many teams drowning in alerts and dreading their time on call? The reason is that we tend to monitor the wrong things: reactive alerts, metrics that we don’t completely understand how they impact our service, and capacity alerts. We look at our own view of the service and fail to consider that our customers have a different view.
Come learn to let go of what does not help, and explore how to monitor for what truly matters: what the customer sees. This starts with defining our agreements with our customers, continues through building applications intelligently and instrumenting all the things, and finishes with picking the right signals out of that instrumentation to generate alerts that are actionable, not ones that introduce confusion and noise. We will also touch on capacity planning, and how it should never wake you up. You’ll find it’s possible to assure that you meet your service level objectives while still maximizing your sleep level objectives.
Redefine Operations in a DevOps World: The New Role for Site Reliability Eng...Todd Palino
Across industries, modern operations teams have noted the emergence of a new role: the Site Reliability Engineer (SRE); a new IT craftsperson who fuses software engineering and operations best practices to enable highly reliable software systems. Once the domain of web-scale businesses, this discipline is both applicable and important for any organization looking to differentiate itself in a world increasingly defined by software.
In this session, Todd Palino from LinkedIn explores SRE from organizational, team and individual perspectives. He’ll describe how by crafting automation and problem solving, SRE can permeate across a technical organization – not only ensuring a massively high-performant and always available site, but used to inform optimum decision making - in everything from system procurement to application design, builds and deployment.
Todd will talk in depth about what constitutes the best in SRE in a DevOps world, using examples to examine the techniques needed to accelerate value and grow teams. Taking the ‘lid-off’ SRE at LinkedIn, join Todd as he describes how it started and continues to evolve, what goals are important, and how it’s instrumental in building a high-trust and inclusive team culture needed to drive continuous improvement -- and importantly, have lots of fun doing it!
Kafka makes so many things easier to do, from managing metrics to processing streams of data. Yet it seems that so many things we have done to this point in configuring and managing it have been object studies in how to make our lives, as the plumbers who keep the data flowing, more difficult than they have to be. What are some of our favorites?
* Kafka without access controls
* Multitenant clusters with no capacity controls
* Worrying about message schemas
* MirrorMaker inefficiencies
* Hope and pray log compaction
* Configurations as shared secrets
* One-way upgrades
We’ve made a lot of progress over the last few years improving the situation, in part by focusing some of this incredibly talented community towards operational concerns. We’ll talk about the big mistakes you can avoid when setting up multi-tenant Kafka, and some that you still can’t. And we will talk about how to continue down the path of marrying the hot, new features with operational stability so we can all continue to come back here every year to talk about it.
I'm No Hero: Full Stack Reliability at LinkedInTodd Palino
The operations engineer is often seen as the hero, toiling away late nights on call to keep the systems running through failures of hardware and of code. While developers try as hard as possible to move quickly and break things, we stand as the voice of reason urging caution. We’re the only ones who truly understand the systems, but you’ll rarely find documentation because it’s just too complex and changeable to write down. When we’re doing our jobs well, we’re unappreciated because nobody understands how difficult it is. When things break, everyone thinks we’re doing our jobs badly. These are not the things we aspire to.
At LinkedIn, Site Reliability Engineers are one layer in a stack that starts with the way we manage our code and basic hardware, and is built with common systems for application management, monitoring, and alerting. Each layer has its own specialist engineers, focused on making their piece as resilient as it can be and building it to integrate with the rest of the stack. This lets Software Engineers concentrate on developing their applications, without having to spend time building systems to build, package, and distribute their code. SREs can dedicate their time to integrating applications with the stack, architecting and scaling deployments, as well as developing tools and documentation to make the job easier. When the inevitable failure happens, many experts come together to quickly identify and resolve the problem and improve the entire stack for everyone.

Kafka is a publish/subscribe messaging system that, while young, forms a vital core for data flow inside many organizations, including LinkedIn. We will discuss Kafka from an Operations point of view, including the use cases for Kafka and the tools LinkedIn has been developing to improve the management of deployed clusters. We'll also talk about some of the challenges of managing a multi-tenant data service and how to avoid getting woken up at 3 AM.

The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
