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.
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 |
|---|---|---|---|
| 2.4 | 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 |
This library is a work in progress so the API may change before the official release.
Please make sure you use documentation from the correct branch (2.4, 2.3, etc).
