Apache Tez is an application framework that allows for complex directed-acyclic-graph (DAG) based processing of data built on Apache Hadoop YARN. It is designed as a successor to MapReduce for executing Hive and Pig queries, providing a flexible API for creating DAG execution pipelines, in-memory data passing between tasks, and session reuse for reduced startup latency. Apache Tez is an Apache Software Foundation top-level project.
