Extending Spark SQL API with Easier to Use Array Types Operations with Marek ...Databricks
Big companies typically integrate their data from various heterogeneous systems when building a data lake as single point for accessing data. To achieve this goal technical teams often deal with data defined by complex schemas and various data formats. Spark SQL Datasets are currently compatible with data formats such as XML, Avro and Parquet by providing primitive and complex data types such as structs and arrays.
Although Dataset API offers rich set of functions, general manipulation of array and deeply nested data structures is lacking. We will demonstrate this fact by providing examples of data which is currently very hard to process in Spark efficiently. We designed and developed an extension of Dataset API to allow developers to work with array and complex type elements in a more straightforward and consistent way. The extension should help users dealing with complex and structured big data to use Apache Spark as a truly generic processing framework.
Dean Wampler gave a talk at the Spark Summit Europe 2016 titled "Just Enough Scala for Spark". He demonstrated coding a demo in Scala for Spark, based on his free online tutorial.

Kafka is becoming an ever more popular choice for users to help enable fast data and Streaming. Kafka provides a wide landscape of configuration to allow you to tweak its performance profile. Understanding the internals of Kafka is critical for picking your ideal configuration. Depending on your use case and data needs, different settings will perform very differently. Lets walk through performance essentials of Kafka. Let's talk about how your Consumer configuration, can speed up or slow down the flow of messages to Brokers. Lets talk about message keys, their implications and their impact on partition performance. Lets talk about how to figure out how many partitions and how many Brokers you should have. Let's discuss consumers and what effects their performance. How do you combine all of these choices and develop the best strategy moving forward? How do you test performance of Kafka? I will attempt a live demo with the help of Zeppelin to show in real time how to tune for performance.

Spark and Object Stores —What You Need to Know: Spark Summit East talk by Ste...Spark Summit
If you are running Apache Spark in cloud environments, Object Stores —such as Amazon S3 or Azure WASB— are a core part of your system. What you can’t do is treat them like “just another filesystem” —do that and things will, eventually, go horribly wrong.
This talk looks at the object stores in the cloud infrastructures, including underlying architectures., compares them to what a “real filesystem” is expected to do and shows how to use object stores efficiently and safely as sources of and destinations of data.
It goes into depth on recent “S3a” work, showing how including improvements in performance, security, functionality and measurement —and demonstrating how to use make best use of it from a spark application.
If you are planning to deploy Spark in cloud, or doing so today: this is information you need to understand. The performance of you code and integrity of your data depends on it.

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!
Internals of Speeding up PySpark with ArrowDatabricks
Back in the old days of Apache Spark, using Python with Spark was an exercise in patience. Data was moving up and down from Python to Scala, being serialised constantly. Leveraging SparkSQL and avoiding UDFs made things better, likewise did the constant improvement of the optimisers (Catalyst and Tungsten). But, after Spark 2.3, PySpark has sped up tremendously thanks to the addition of the Arrow serialisers. In this talk you will learn how the Spark Scala core communicates with the Python processes, how data is exchanged across both sub-systems and the development efforts present and underway to make it as fast as possible.
An Introduction to Confluent Cloud: Apache Kafka as a Serviceconfluent

The sessions focused on how Kafka and the Confluent Platform work, how their main subsystems interact, and how to set up, manage, monitor, and tune your cluster.
Apache Spark Based Reliable Data Ingestion in Datalake with Gagan AgrawalDatabricks
Ingesting data from variety of sources like Mysql, Oracle, Kafka, Sales Force, Big Query, S3, SaaS applications, OSS etc. with billions of records into datalake (for reporting, adhoc analytics, ML jobs) with reliability, consistency, schema evolution support and within expected SLA has always been a challenging job. Also ingestion may have different flavors like full ingestion, incremental ingestion with and without compaction/de-duplication and transformations with their own complexity of state management and performance. Not to mention dependency management where hundreds / thousands of downstream jobs are dependent on this ingested data and hence data availability on time is of utmost importance. Most data teams end up creating adhoc ingestion pipelines written in different languages and technologies which adds operational overheads and knowledge is mostly limited to few.
In this session, I will talk about how we leveraged Sparks Dataframe abstraction for creating generic ingestion platform capable of ingesting data from varied sources with reliability, consistency, auto schema evolution and transformations support. Will also discuss about how we developed spark based data sanity as one of the core components of this platform to ensure 100% correctness of ingested data and auto-recovery in case of inconsistencies found. This talk will also focus how Hive table creation and schema modification was part of this platform and provided read time consistencies without locking while Spark Ingestion jobs were writing on the same Hive tables and how we maintained different versions of ingested data to do any rollback if required and also allow users of this ingested data to go back in time and read snapshot of ingested data at that moment.
Post this talk one should be able to understand challenges involved in ingesting data reliably from different sources and how one can leverage Spark’s Dataframe abstraction to solve this in unified way.

A Deep Dive into Stateful Stream Processing in Structured Streaming with Tath...Databricks
Stateful processing is one of the most challenging aspects of distributed, fault-tolerant stream processing. The DataFrame APIs in Structured Streaming make it very easy for the developer to express their stateful logic, either implicitly (streaming aggregations) or explicitly (mapGroupsWithState). However, there are a number of moving parts under the hood which makes all the magic possible. In this talk, I am going to dive deeper into how stateful processing works in Structured Streaming.
In particular, I’m going to discuss the following.
• Different stateful operations in Structured Streaming
• How state data is stored in a distributed, fault-tolerant manner using State Stores
• How you can write custom State Stores for saving state to external storage systems.

Research shows that using visual and audio aids engages two senses for more effective information retention compared to a single sense. The document provides tips for effective use of audiovisual tools in presentations and advises only using visuals that support learning without distraction.
The document discusses communication skills and effective communication. It defines communication as the exchange of information through various senses and channels. It emphasizes that communication skills are important for careers and personal relationships. Effective communication involves sending clear, concise messages and properly understanding messages received through various verbal, nonverbal, and paraverbal means. Barriers to communication like organizational issues or personal attitudes can interfere with the exchange of information.
The document discusses the four main types of communication: verbal communication, non-verbal communication, written communication, and visual communication. It provides details on each type, including that verbal communication involves speaking, non-verbal communication is physical ways of communicating without words, written communication includes business letters and newsletters, and visual communication displays information visually through images, signs, and electronic forms like video. The document also shares information on specific communication methods like public speaking, body language, email, and the internet.
Communication is the process of transmitting information from one person to another. It involves the transmission of a message from a sender to a receiver through an agreed-upon channel. The communication process consists of a sender encoding a message and selecting a channel to transmit it through, the receiver decoding the message, and the receiver providing feedback to the sender. Effective communication is a two-way process of sharing information and building understanding between individuals.
Written and oral communication are both important skills for business. Written communication provides a permanent record but is time-consuming, while oral communication allows for interaction but lacks permanence. To develop effective communication skills, it is important to consider the audience, choose an appropriate tone, and convey information clearly and concisely. Both written and oral communication have advantages and disadvantages for business situations.

Understanding User Needs and Satisfying ThemAggregage

We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
