---------------------------------
Summary: 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
Fix For: 1.4.0
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.
