Apache Tez

aid: apache-tez
name: Apache Tez
description: 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.

  name: Apache Tez DAG API
  description: The Tez DAG API provides a Java programming model for defining and submitting directed-acyclic-graph (DAG)
    computation jobs to Apache YARN. It allows building DAGs composed of Vertex (processing units), Edge (data connections
    between vertices), and Processor implementations. The API supports data source/sink definitions, vertex grouping, fault
    tolerance configuration, and monitoring via the Tez UI and REST API.

  name: Apache Tez UI REST API
  description: The Tez UI and YARN Application History Server expose REST endpoints for monitoring Tez application history,
    DAG details, vertex and task statistics. The Tez Timeline Server integration provides historical data for DAGs, vertices,
    tasks, and task attempts with detailed resource usage and timing information.
