OpenStack is about standard APIs and everyone should be happy. But is it so? Challenges in working with all these distrosWebinar Slides: Become a MongoDB DBA (if you’re really a MySQL user)
So, maybe you’ve been working with MySQL for a while and are now being asked to also properly maintain one or more MongoDB instances. It is not uncommon that MySQL DBAs, developers, network/system administrators or DevOps folks with general backgrounds, find themselves in this situation at some point in time. In fact, with more organisations operating polyglot environments, it’s starting to become commonplace.
With that said, we’d like to introduce a new webinar series: ‘How to Become a MongoDB DBA’ to answer the question: ‘what does a MongoDB DBA do’?
In the space of three webinars, we will walk you through the most important tasks a MongoDB DBA routinely goes through and provide you with options on how to best complete these tasks.
In this initial webinar of the series, we will go beyond the deployment phase and show you how you can automate tasks, how to monitor a cluster and how to manage MongoDB; whilst also automating and managing your MySQL and/or PostgreSQL installations.

Strimzi - Where Apache Kafka meets OpenShift - OpenShift Spain MeetUp
Apache Kafka is the most used data streaming broker by companies. It could manage millions of messages easily and it is the base of many architectures based in events, micro-services, orchestration, ... and now cloud environments. OpenShift is the most extended Platform as a Service (PaaS). It is based in Kubernetes and it helps the companies to deploy easily any kind of workload in a cloud environment. Thanks many of its features it is the base for many architectures based in stateless applications to build new Cloud Native Applications. Strimzi is an open source community that implements a set of Kubernetes Operators to help you to manage and deploy Apache Kafka brokers in OpenShift environments.
These slides will introduce you Strimzi as a new component on OpenShift to manage your Apache Kafka clusters.

Finally, it briefly outlines related tools like Kafka Connect and Kafka Streams that build upon the Kafka platform.
Kafka’s New Control Plane: The Quorum Controller | Colin McCabe, Confluent
Currently, Apache Kafka® uses Apache ZooKeeper™ to store its metadata. Data such as the location of partitions and the configuration of topics are stored outside of Kafka itself, in a separate ZooKeeper cluster. In 2019, we outlined a plan to break this dependency and bring metadata management into Kafka itself through a dynamic service that runs inside the Kafka Cluster. We call this the Quorum Controller.
In this talk, we’ll look at how the Quorum Controller works and how it integrates with other parts of the next-generation Kafka architecture, such as the Raft quorum and snapshotting mechanism. We’ll also explain how the Quorum Controller will simplify operations, improve security, and enhance scalability and performance.
Finally, we’ll look at some of the practicalities, such as how to monitor and run the Quorum Controller yourself. We’ll talk about some of the performance gains we’ve seen, and our plans for the future.

Headless Android at AnDevCon3
Headless Android allows running the full Android system stack without any graphical user interface elements. This is done by disabling SurfaceFlinger, WindowManager and other UI services. The result is a smaller memory footprint but full access to Android services, APIs, and development tools. Key changes include tweaking internal calls to disable expectations of a graphical environment and starting components with 'am' instead of activities. This produces a streamlined Android configuration for embedded and automation use cases.

Gabriele Bartolini - Vice President/CTO of Cloud Native and Kubernetes, EDB
ABSTRACT OF THE TALK
Imagine this: you have a virtual infrastructure based on Kubernetes, made up of virtual data centers, possibly spread across multiple Kubernetes clusters and regions. Your infrastructure could even be hosted on premises or on different cloud service providers. Infrastructure as Code is a requirement. You’ve been tasked to run Postgres databases, alongside your applications.
The good news is that you can leverage a fully open source stack with Kubernetes, PostgreSQL and the CloudNativePG operator, and deploy your Postgres database in the same way you deploy applications.
Join me in this webinar to discover the key role that you have to make this succeed, starting from day 0 through day 2 operations.
I’ll share some examples and best practices for running Postgres databases in Kubernetes, before peeking at the new features we are developing for the months to come.

Is Using KoP (Kafka-on-Pulsar) a Good Idea? - Pulsar Summit SF 2022
So, you are a responsible software engineer building microservices for Apache Kafka, and life is good. Eventually, you hear the community talking about the outstanding experience they are having with Apache Pulsar features. They talk about infinite event stream retention, a rebalance-free architecture, native support for event processing, and multi-tenancy. Exciting, right? Most people would want to migrate their code to Pulsar. Especially when you know that Pulsar also supports Kafka clients natively via the protocol handler known as KoP — which enables the Kafka client APIs on Pulsar. But, as said before, you are responsible; and you don't believe in fairy tales, just like you don't believe that migrations like this happen effortlessly. This session will discuss the architecture behind protocol handlers, what it means having one enabled on Pulsar, and how the KoP works. It will detail the effort required to migrate a microservice written for Kafka to Pulsar, and whether the code need to change for this.
Building an Asynchronous Application Framework with Python and Pulsar - Pulsa...
This talk describes Klaviyo’s internal messaging system, an asynchronous application framework built around Pulsar that provides a set of high-quality tools for building business-critical asynchronous data flows in unreliable environments. This framework includes: a pulsar ORM and schema migrator for topic configuration; a retry/replay system; a versioned schema registry; a consumer framework oriented around preventing message loss and in hostile environments while maximizing observability; an experimental “online schema change” for topics; and more. Development of this system was informed by lessons learned during heavy use of datastores like RabbitMQ and Kafka, and frameworks like Celery, Spark, and Flink. In addition to the capabilities of this system, this talk will also cover (sometimes painful) lessons learned about the process of converting a heterogenous async-computing environment onto Pulsar and a unified model.

They talk about infinite event stream retention, a rebalance-free architecture, native support for event processing, and multi-tenancy. Exciting, right? Most people would want to migrate their code to Pulsar. Especially when you know that Pulsar also supports Kafka clients natively via the protocol handler known as KoP — which enables the Kafka client APIs on Pulsar. But, as said before, you are responsible; and you don't believe in fairy tales, just like you don't believe that migrations like this happen effortlessly. This session will discuss the architecture behind protocol handlers, what it means having one enabled on Pulsar, and how the KoP works. It will detail the effort required to migrate a microservice written for Kafka to Pulsar, and whether the code need to change for this.
Building an Asynchronous Application Framework with Python and Pulsar - Pulsa...
This talk describes Klaviyo’s internal messaging system, an asynchronous application framework built around Pulsar that provides a set of high-quality tools for building business-critical asynchronous data flows in unreliable environments. This framework includes: a pulsar ORM and schema migrator for topic configuration; a retry/replay system; a versioned schema registry; a consumer framework oriented around preventing message loss and in hostile environments while maximizing observability; an experimental “online schema change” for topics; and more. Development of this system was informed by lessons learned during heavy use of datastores like RabbitMQ and Kafka, and frameworks like Celery, Spark, and Flink. In addition to the capabilities of this system, this talk will also cover (sometimes painful) lessons learned about the process of converting a heterogenous async-computing environment onto Pulsar and a unified model.
Blue-green deploys with Pulsar & Envoy in an event-driven microservice ecosys...
The document discusses Toast's adoption and use of Apache Pulsar for asynchronous messaging in their microservices architecture. It describes how they built a "Pulsar Toggle" leveraging Envoy proxy to enable blue/green deployments of Pulsar consumers. The Pulsar Toggle allows consumers to be paused and resumed based on their status in the Envoy control plane, improving the reliability and usability of deploying changes to Pulsar-based services. Toast has seen increased adoption of Pulsar and benefits from its stability and scalability.
Distributed Database Design Decisions to Support High Performance Event Strea...
Event streaming architectures launched a reexamination of applications and systems architectures across the board. We live in a world where answers are needed now in a constant real-time flow. Yet beyond the event streaming system itself, what are the corequisites to ensure our large scale distributed database systems can keep pace with this always-on, always-current real time flow of data? What are the requirements and expectations for this next tech cycle?
Simplify Pulsar Functions Development with SQL - Pulsar Summit SF 2022
Pulsar Functions is a succinct framework provided by Apache Pulsar to conduct real-time data processing. Its use cases include ETL pipeline, event-driven applications, and simple data analytics. While Pulsar Functions already provides an extremely simple programming interface, we want to further lower the barrier for users to access real-time data. Since SQL is one of the universal languages in the technology world and well accepted by the vast majority of data engineers, we decided to add a SQL expressing layer on top of Pulsar Functions runtime. In this talk, we will discuss the architecture and implementation of this new service. We will see how SQL syntax, Pulsar Functions, and Function Mesh can work together to deliver a unique user development experience for real-time data jobs in the cloud environment. We will also walk through use cases like filtering, routing, and projecting messages as well as integrating with the Pulsar IO Connectors framework.
Towards a ZooKeeper-less Pulsar, etcd, etcd, etcd. - Pulsar Summit SF 2022
This document summarizes Matteo Merli's talk on moving Apache Pulsar to a ZooKeeper-less metadata model. It discusses how Pulsar currently uses ZooKeeper for metadata storage but faces scalability issues. The talk outlines PIP-45, a plan to introduce a pluggable metadata backend into Pulsar to replace the direct ZooKeeper usage. This would allow alternative storage options like Etcd and improve scalability. It also discusses successes already achieved in Pulsar 2.10 by abstracting the metadata access and future goals around scaling to support millions of topics.
Validating Apache Pulsar’s Behavior under Failure Conditions - Pulsar Summit ...
Apache Pulsar is a highly available, distributed messaging system that provides guarantees of no message loss and strong message ordering with predictable read and write latency. In this talk, learn how this can be validated for Apache Pulsar Kubernetes deployments. Various failures are injected using Chaos Mesh to simulate network and other infrastructure failure conditions. There are many questions that are asked about failure scenarios, but it could be hard to find answers to these important questions. When a failure happens, how long does it take to recover? Does it cause unavailability? How does it impact throughput and latency? Are the guarantees of no message loss and strong message ordering kept, even when components fail? If a complete availability zone fails, is the system configured correctly to handle AZ failures? This talk will help you find answers to these questions and apply the tooling and practices to your own testing and validation.
Cross the Streams! Creating Streaming Data Pipelines with Apache Flink + Apac...
Despite what the Ghostbusters said, we’re going to go ahead and cross (or, join) the streams. This session covers getting started with streaming data pipelines, maximizing Pulsar’s messaging system alongside one of the most flexible streaming frameworks available, Apache Flink. Specifically, we’ll demonstrate the use of Flink SQL, which provides various abstractions and allows your pipeline to be language-agnostic. So, if you want to leverage the power of a high-speed, highly customizable stream processing engine without the usual overhead and learning curves of the technologies involved (and their interconnected relationships), then this talk is for you. Watch the step-by-step demo to build a unified batch and streaming pipeline from scratch with Pulsar, via the Flink SQL client. This means you don’t need to be familiar with Flink, (or even a specific programming language). The examples provided are built for highly complex systems, but the talk itself will be accessible to any experience level.
Message Redelivery: An Unexpected Journey - Pulsar Summit SF 2022
This document summarizes the message redelivery process in Apache Pulsar. It discusses how messages are redelivered when producing or consuming messages. When producing, messages are redelivered if the broker does not acknowledge receipt in a timely manner. When consuming, messages are redelivered under three circumstances: if the acknowledgment times out, if messages are negatively acknowledged, or if delivery is delayed. The document provides details on the commands and objects involved in establishing connections, publishing, consuming, acknowledging, and redelivering messages between Pulsar clients and brokers.
Unlocking the Power of Lakehouse Architectures with Apache Pulsar and Apache ...
Lakehouses are quickly growing in popularity as a new approach to Data Platform Architecture bringing some of the long-established benefits from OLTP world to OLAP, including transactions, record-level updates/deletes, and changes streaming. In this talk, we will discuss Apache Hudi and how it unlocks possibilities of building your own fully open-source Lakehouse featuring a rich set of integrations with existing technologies, including Apache Pulsar. In this session, we will present: - What Lakehouses are, and why they are needed. - What Apache Hudi is and how it works. - Provide a use-case and demo that applies Apache Hudi’s DeltaStreamer tool to ingest data from Apache Pulsar.
Understanding Broker Load Balancing - Pulsar Summit SF 2022
Pulsar is a horizontally scalable messaging system, so the traffic in a logical cluster must be balanced across all the available Pulsar brokers as evenly as possible, in order to ensure full utilization of the broker layer. You can use multiple settings and tools to control the traffic distribution which requires a bit of context to understand how the traffic is managed in Pulsar. In this talk, we will walk you through the load balancing capabilities of Apache Pulsar, and highlight some of the control mechanisms available to control the distribution of load across the Pulsar brokers. Finally, we will discuss the various loading shedding strategies that are available. At the end of the talk, you will have a better understanding of how Pulsar's broker level auto-balancing works, and how to properly configure it to meet your workload demands.

Pulsar's Journey in Yahoo!: On-prem, Cloud and Hybrid - Pulsar Summit SF 2022
In today’s world, we are seeing a big shift toward the Cloud. With this shift comes a big shift in the expectations we have for a messaging system, especially when the messaging system is presented as managed service in a large-scale, multi-tenant environment. For any large-scale enterprise, it’s very important to evaluate messaging system and be confident before expanding complex distributed data systems like Apache Pulsar from on-premise to elastically scalable, fully managed services on cloud services. We must consider aspects such as: migration from and integration with large-scale on-premise clusters, security, cost efficiency, and the cloud friendliness of the architecture, modeling cost and capacity, tenant isolation, deployment robustness, availability, monitoring, etc. Not every messaging system is built to be cloud-native and run as a managed service with cost efficiency. We have been running large-scale Apache Pulsar at Yahoo for the last 8 years on various platforms and hardware configurations while meeting application SLAs and serving more than 1M topics in a cluster. In this talk, we will talk about Pulsar’s journey in Yahoo! from an on-premise platform to a hybrid cloud and on-premise system. We will talk about Pulsar’s architecture and features that make Pulsar a good cloud-native messaging-system choice for any enterprise.

The keynote aims to explain how Pulsar solves challenges in building complex event-driven applications.
Pulsar @ Scale. 200M RPM and 1K instances - Pulsar Summit SF 2022
Our services team creates, builds, and maintains the as a service offering for base platform services within our organization. Several thousand applications use these custom services daily generating more than 700 million requests per minute. One of these services was our publish / subscriber offering, BQ with custom SDK and custom metrics based on Apache Pulsar. BQ is the core communication service within our organization, having more 200M RPM. All the core processes of the organization depend on this service for operation: the CDC of any of our RDBMS or NoSQL offering, all the eventing efforts of the organization, async communication between apps, notification systems, etc. The backend of the solution was Apache Pulsar running on EC2 on AWS and on top of that we built several components as wrappers of the actual backend, creating our own SDKs and abstractions and in many ways extending the features provided by Pulsar. We had a multi-cluster setup 100% on AWS, with custom Pulsar Docker images running on large ASG setups, along with our own wrapping and admin APIs and DBs. All of this in turn transformed the solution into a volatile solution.

Log System As Backbone – How We Built the World’s Most Advanced Vector Databa...
Milvus is an open-source vector database that leverages a novel data fabric to build and manage vector similarity search applications. As the world's most popular vector database, it has already been adopted in production by thousands of companies around the world, including Lucidworks, Shutterstock, and Cloudinary. With the launch of Milvus 2.0, the community aims to introduce a cloud-native, highly scalable and extendable vector similarity solution, and the key design concept is log as data.
Milvus relies on Pulsar as the log pub/sub system. Pulsar helps Milvus to reduce system complexity by loosely decoupling each micro service, making the system stateless by disaggregating log storage and computation, which also makes the system further extendable. We will introduce the overview design, the implementation details of Milvus and its roadmap in this topic.
Takeaways:
1) Get a general idea about what is a vector database and its real-world use cases.
2) Understand the major design principles of Milvus 2.0.
3) Learn how to build a complex system with the help of a modern log system like Pulsar.

选择实体注册公司办理，更放心，更安全！我们的承诺：客户在留信官方认证查询网站查询到认证通过结果后付款，不成功不收费！
