Accelerating query processing with materialized views in Apache Hive
 
40:32
Over the last few years, the Apache Hive community has been working on advancements to enable a full new range of use cases for the project, moving from its batch processing roots towards a SQL interactive query answering platform. Traditionally, one of the most powerful techniques used to accelerate query processing in data warehouses is the precomputation of relevant summaries or materialized views. This talk presents our work on introducing materialized views and automatic query rewriting based on those materializations in Apache Hive. In particular, materialized views can be stored natively in Hive or in other systems such as Druid using custom storage handlers, and they can seamlessly exploit new exciting Hive features such as LLAP acceleration. Then the optimizer relies in Apache Calcite to automatically produce full and partial rewritings for a large set of query expressions comprising projections, filters, join, and aggregation operations. We shall describe the current coverage of the rewriting algorithm, how Hive controls important aspects of the life cycle of the materialized views such as the freshness of their data, and outline interesting directions for future improvements. We include an experimental evaluation highlighting the benefits that the usage of materialized views can bring to the execution of Hive workloads.

Use NOCOPY to Improve Performance
 
05:15
The NOCOPY parameter hint tells the PL/SQL compiler to pass OUT and IN-OUT parameters "by reference" (meaning: do not copy in, nor copy out). The result is better performance and reduced PGA consumption. ====================================== Practically Perfect PL/SQL with Steven Feuerstein Copyright © 2015 Oracle and/or its affiliates.
