fluent-plugin-riak2f, a plugin for Fluentd

fluent-plugin-riak2f is a fluentd output plugin designed to stuff log messages into a riak cluster.

This version is based on the work of fluent-plugin-riak2. We are very thankful for his effort and his decision to release the work under the Apache 2 license.

fluent-plugin-riak2 is designed to be used with Riak 2.x clusters and it's yokozuna/solr based search engine. Support for secondary indicies is limited and should be considered deprecated.

Riak ( http://github.com/basho/riak ) is an open-source distributed KVS focused on availability.

Current status is still proof-of-concept: index setting and its configuration are to be decided. Also performance optimization is required. Another idea is in_tail_riak by using riak post-commit.

installation

$ sudo gem install fluent-plugin-riak2f

Notice: you need Riak configured using eleveldb as backend.
