New Developments in the Open Source Ecosystem: Apache Spark 3.0, Delta Lake, and KoalasSummit Europe 2019

In this talk, we will highlight major efforts happening in the Spark ecosystem. In particular, we will dive into the details of adaptive and static query optimizations in Spark 3.0 to make Spark easier to use and faster to run. We will also demonstrate how new features in Koalas, an open source library that provides Pandas-like API on top of Spark, helps data scientists gain insights from their data quicker.

Productizing Structured Streaming JobsSummit 2019

Structured Streaming was a new streaming API introduced to Spark over 2 years ago in Spark 2.0, and was announced GA as of Spark 2.2. Databricks customers have processed over a hundred trillion rows in production using Structured Streaming. We received dozens of questions on how to best develop, monitor, test, deploy and upgrade these jobs. In this talk, we aim to share best practices around what has worked and what hasn't across our customer base. We will tackle questions around how to plan ahead, what kind of code changes are safe for structured streaming jobs, how to architect streaming pipelines which can give you the most flexibility without sacrificing performance by using tools like Databricks Delta, how to best monitor your streaming jobs and alert if your streams are falling behind or are actually failing, as well as how to best test your code.

Building Robust Production Data Pipelines with Databricks DeltaSummit 2019

Most data practitioners grapple with data quality issues and data pipeline complexities—it's the bane of their existence. Data engineers, in particular, strive to design and deploy robust data pipelines that serve reliable data in a performant manner so that their organizations can make the most of their valuable corporate data assets. Databricks Delta, part of Databricks Runtime, is a next-generation unified analytics engine built on top of Apache Spark. Built on open standards, Delta employs co-designed compute and storage and is compatible with Spark API’s. It powers high data reliability and query performance to support big data use cases, from batch and streaming ingests, fast interactive queries to machine learning. In this tutorial we will discuss the requirements of modern data pipelines, the challenges data engineers face when it comes to data reliability and performance and how Delta can help. Through presentation, code examples and notebooks, we will explain pipeline challenges and the use of Delta to address them. You will walk away with an understanding of how you can apply this innovation to your data architecture and the benefits you can gain. This tutorial will be both instructor-led and hands-on interactive session. Instructions in how to get tutorial materials will be covered in class. WHAT YOU’LL LEARN: – Understand the key data reliability and performance data pipelines challenges – How Databricks Delta helps build robust pipelines at scale – Understand how Delta fits within an Apache Spark™ environment – How to use Delta to realize data reliability improvements – How to deliver performance gains using Delta PREREQUISITES: – A fully-charged laptop (8-16GB memory) with Chrome or Firefox – Pre-register for Databricks Community Edition

Designing and Building Next Generation Data Pipelines at Scale with Structured StreamingSummit Europe 2018

Lambda architectures, data warehouses, data lakes, on-premise Hadoop deployments, elastic Cloud architecture… We’ve had to deal with most of these at one point or another in our lives when working with data. At Databricks, we have built data pipelines, which leverage these architectures. We work with hundreds of customers who also build similar pipelines. We observed some common pain points along the way: the HiveMetaStore can easily become a bottleneck, S3’s eventual consistency is annoying, file listing anywhere becomes a bottleneck once tables exceed a certain scale, there’s not an easy way to guarantee atomicity - garbage data can make it into the system along the way. The list goes on and on. Fueled with the knowledge of all these pain points, we set out to make Structured Streaming the engine to ETL and analyze data. In this talk, we will discuss how we built robust, scalable, and performant multi-cloud data pipelines leveraging Structured Streaming, Databricks Delta, and other specialized features available in Databricks Runtime such as file notification based streaming sources and optimizations around Databricks Delta leveraging data skipping and Z-Order clustering. You will walkway with the essence of what to consider when designing scalable data pipelines with the recent innovations in Structured Streaming and Databricks Runtime. Session hashtag: #SAISDev15
