Elasticsearch distributed journal for Akka persistence

Elasticsearch distributed journal for Akka persistence (elasticsearch 2.3.3)

Akka persistence distributed journal based on Elasticsearch.

This fork uses elasticsearch version 2.3.3 which is not backward compatible with the original 1.7.1 version.

Configuration

akka.persistence.journal.plugin = "elasticsearch-journal"
akka.persistence.snapshot-store.plugin = "elasticsearch-snapshot-store"

elasticsearch-journal {
  class = "com.github.nilsga.akka.persistence.elasticsearch.ElasticsearchAsyncWriteJournal"
}

elasticsearch-snapshot-store {
  class = "com.github.nilsga.akka.persistence.elasticsearch.ElasticsearchSnapshotStore"
}

elasticsearch-persistence {
  nodes = ["localhost"]
  cluster = "mycluster"
  index = "akkajournal"
}

Note: You don't need both the journal and the snapshot store plugin. Just add the plugin that your application is using.

• elasticsearch-persistence.nodes is an array of addresses to the ES master nodes of the cluster
• elasticsearch-persistence.cluster is the name of the ES cluster to join
• elasticsearch-persistence.index is the name of the index to use for the journal

Why would I use a search engine as a journal?

You probably wouldn't, unless you already have ES as a part of your infrastructure, and don't want to introduce yet another component.
