Spark-Redis

A library for reading and writing data in Redis using Apache Spark.

Spark-Redis provides access to all of Redis' data structures - String, Hash, List, Set and Sorted Set - from Spark as RDDs. It also supports reading and writing with DataFrames and Spark SQL syntax.

The library can be used both with Redis stand-alone as well as clustered databases. When used with Redis cluster, Spark-Redis is aware of its partitioning scheme and adjusts in response to resharding and node failure events.

Spark-Redis also supports Spark Streaming (DStreams) and Structured Streaming.

Version compatibility and branching

The library has several branches, each corresponds to a different supported Spark version. For example, 'branch-2.3' works with any Spark 2.3.x version. The master branch contains the recent development for the next release.

Spark-Redis	Spark	Redis	Supported Scala Versions
master	3.2.x	>=2.9.0	2.12
3.0	3.0.x	>=2.9.0	2.12
2.4, 2.5, 2.6	2.4.x	>=2.9.0	2.11, 2.12
2.3	2.3.x	>=2.9.0	2.11
1.4	1.4.x		2.10
