Tech-Talk 1: Apache Spark at Adobe

Abstract:

The Adobe Cloud Platform is a multi-tenant, big data stack as a service on the cloud which provides the modern foundation for all the various parts of the Adobe Experience Cloud.

From a data processing perspective, Adobe uses Apache Spark in a variety of scenarios. We will talk about the high-level data architecture, briefly touching on the infrastructure/scale/challenges, and lastly, we will cover how we are leveraging Spark.

As part of the Cloud Platform, we have also built a Query Engine leveraging Spark SQL for ad-hoc data querying. The Query Engine has implemented a PostgreSQL protocol and leverages Akka Streams and the Presto Parser as an abstraction layer around Spark SQL. We will talk about the high-level architecture and talk about the various patches made to Spark SQL such as support for nested column pruning that are critical to our performance needs when accessing data with thousands of nested columns.

Tech-Talk 2: Upcoming Apache Spark 2.4: What’s New & Why Should You Care
Abstract:

The upcoming Apache Spark 2.4 release is the fifth release in the 2.x series. This talk will provide an overview of the major features and enhancements in this upcoming release.

* A new scheduling model (Barrier Scheduling) to enable users to properly embed distributed Deep Learning training as a Spark stage to simplify the distributed training workflow.
* 35 high-order functions are added for manipulating arrays/maps in Spark SQL.
* A new native AVRO data source, based on Databricks' spark-avro module.
* PySpark also introduces eager evaluation mode on all operations for teaching and debuggability.
* Spark on K8S adds PySpark and R support and client-mode support.
* Various enhancements in structured streaming. e.g., stateful operators in continuous processing.
* Various performance improvement in built-in data sources. e.g., Parquet nested schema pruning.
