Investigate solution for deploying ElasticSearch EPN on FSW 6.0 --------------------------------------------------------------- Key: RTGOV-416 URL: https://issues.jboss.org/browse/RTGOV-416 Project: RTGov (Run Time Governance) Issue Type: Sub-task Reporter: Gary Brown Assignee: Gary Brown Fix For: 2.0.0.Final 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.
