ElasticsearchIndexNaming

class ElasticsearchIndexNaming(val prefix: String = "")

The names Wow gives its Elasticsearch indices and index templates on one cluster.

prefix is put verbatim before every name Wow derives: the snapshot and event stream indices ({prefix}wow.{context}.{aggregate}.snapshot|es), the index templates ({prefix}wow-snapshot-template, …) and their index_patterns ({prefix}wow.*.snapshot, …), so deployments with different prefixes share a cluster without reading or writing each other's indices. Empty (the default), every name is the one IndexNameConverter gives.

An index definition shipped under META-INF/wow/elasticsearch/ keeps its unprefixed file name: it describes the aggregate's index whatever the deployment's prefix.
