Serge Huber commented on UNOMI-225:
-----------------------------------
I'm not sure it makes sense to support ES 5 once we provide ES 7 as ES 5 is
already EOL (End Of Life) : https://www.elastic.co/support/eol
I think we should just concentrate on making it compatible with ES 7. Maybe in
the future we might want to support multiple versions, but also (possibly)
multiple back-ends such as Solr.
> Upgrade backend to ElasticSearch 7

> Key: UNOMI-225
> URL: https://issues.apache.org/jira/browse/UNOMI-225
> Project: Apache Unomi
> Issue Type: Bug
> Components: core
> Affects Versions: 1.4.0
> Reporter: Serge Huber
> Priority: Major
> Fix For: 1.5.0
>
>
> Currently the backend persistence system only supports ElasticSearch 5.6
> We should upgrade it to support ES 7, but this implies:
> - splitting types into seperate indices
> - switching from the ES Java Transport Client to the ES Java High Level Client
> - improving at the same time ways that data is stored to make it easier to
> sync between multiple ES cluster, for example to synchronize profiles and
> events in multiple data centers and centralize them.
> - improve multi-tenant support
