Hi everyone,

the next Payara release 5.182 will contain a Hazelcast based Eclipselink L2 cache coordination TransportManager as tech preview. It can be activated

setting the following property in the persistence.xml file:

<property name="eclipselink.cache.coordination.protocol"
value="fish.payara.persistence.eclipselink.cache.coordination.HazelcastPublishingTransportManager"/>

To adjust the name of the channel this TransportManager uses with Hazelcast you can set

<property name="eclipselink.cache.coordination.channel" value="EclipseLinkCommandChannel" />

Any feedback is welcome.

Cheers,
Sven

Great feature,

Just out of interest because I am evaluating EclipseLink's cache-coordination: Why did you not use the "standard" EclipseLink extension to do the cache-coordination via JGroups? https://wiki.eclipse.org/EclipseLink/Examples/JPA/CacheCoordination#JGroups

Are there reasons/advantages with Hazelcast?

Cheers,
Daniel

Hi Daniel,

this was a task to extend Payaras capabilities concerning cache coordination and Hazelcast is the servers choice for

their clustering and data grid features.

Cheers,

Sven
