- The document discusses SparkSQL and Parquet as part of Appier's data pipeline. Appier uses SparkSQL with Parquet on HDFS to enable SQL queries on large datasets and support machine learning applications. - Parquet was chosen because it has good performance, supports nested data structures, and is the preferred file format for SparkSQL. Storing data in Parquet files on HDFS provides a low-cost and scalable solution that gives Appier full control over their data. - SparkSQL allows any Spark or SQL code to be reused across ETL, machine learning, and SQL querying applications. This makes development and maintenance more efficient for Appier's data team.

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.

Apache Spark and Object StoresSteve Loughran

This document discusses using Apache Spark with object stores like Amazon S3 and Microsoft Azure Blob Storage.

An Overview on Optimization in Apache Hive: Past, Present, FutureDataWorks Summit

Apache Hive has been continuously evolving to support a broad range of use cases, bringing it beyond its batch processing roots to its current support for interactive queries with sub-second response times using LLAP. However, the development of its execution internals is not sufficient to guarantee efficient performance, since poorly optimized queries can create a bottleneck in the system. Hence, each release of Hive has included new features for its optimizer aimed to generate better plans and deliver improvements to query execution. In this talk, we present the development of the optimizer since its initial release. We describe its current state and how Hive leverages the latest Apache Calcite features to generate the most efficient execution plans. We show numbers demonstrating the improvements brought to Hive performance, and we discuss future directions for the next-generation Hive optimizer, which include an enhanced cost model, materialized views support, and complex query decorrelation.
