=== Redis input plugin

include::{include_path}/plugin_header.asciidoc[]

==== Description

This input will read events from a Redis instance; it supports both Redis channels and lists.
The list command (BLPOP) used by Logstash is supported in Redis v1.3.1+, and
the channel commands used by Logstash are found in Redis v1.3.8+.
While you may be able to make these Redis versions work, the best performance
and stability will be found in more recent stable versions.  Versions 2.6.0+
are recommended.

For more information about Redis, see <http://redis.io/>

`batch_count` note: If you use the `batch_count` setting, you *must* use a Redis version 2.6.0 or
newer. Anything older does not support the operations used by batching.
