> This task is to investigate options for supporting ElasticSearch capabilities in FSW 6.0.
> RTGOV-342 has provided an event processor for ElasticSearch. However this introduces a new 'service' to represent a KeyValueStore, which ElasticSearch is the first implementation.
> If we want to deploy an ElasticSearch based EPN, this new abstract class (currently located in rtgov-commons) is the only issue.
> There are two current proposed solutions:
> 1) Move the abstract class (within the same package) into the rtgov-elasticsearch package as a temporary measure for the next release.
> The issue with this potential solution is if the jars in FSW6.0 are signed - then it won't be possible to have two jars containing classes in the same package.
> 2) Another temporary solution for the next community release would be to inherit the ElasticSearchKeyValueStore directly from the Service abstract class.
> The implication of this would be the EPN's would need to directly use the ElasticSearchKeyValueStore class, rather than the more generic KeyValueStore class - which means that it won't simply be a configuration change to be able to use an alternative KeyValueStore implementation.
> However, as the ElasticSearchKeyValueStore will be the only implementation at that point, then this would work - we would just need to remember to change the EPN's java code after the release, to again use the generic KeyValueStore abstract class.
> At this point, the second option appears to be best, as it localises the changes to the rtgov-elasticsearch module. The rtgov-commons module can remain untouched.
