> Allow user to change field name conversion when indexing to Elasticsearch
> -------------------------------------------------------------------------

> Key: METRON-1569
> URL: https://issues.apache.org/jira/browse/METRON-1569
> Project: Metron
> Issue Type: Improvement
> Reporter: Nick Allen
> Assignee: Nick Allen
> Priority: Major
>
> The `ElasticsearchWriter` has a mechanism to transform the field names of a
> message before it is written to Elasticsearch. Right now this mechanism is
> hard-coded to replace all '.' dots with ':' colons.
> This mechanism was needed for Elasticsearch 2.x which did not allow dots in
> field names. Now that Metron supports Elasticsearch 5.x this is no longer a
> problem.
> A user should be able to configure the field name transformation when writing
> to Elasticsearch, as needed.
> While it might have been simpler to just remove the de-dotting mechanism,
> this would break backwards compatibility. Providing users with a means to
> configure this mechanism provides them with an upgrade path.
