[jira] [Comment Edited] (IGNITE-14402) Java Thin: Continuous Query
[ https://issues.apache.org/jira/browse/IGNITE-14402?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17308603#comment-17308603 ]

--------------------------------------------------------------------
[~alex_pl] So we have a few options:
* Ignore JCache completely and create interfaces from scratch - not good - hard to switch from thick to thin and back
* Implement JCache fully - too big of a task right now
* Implement JCache partially and throw exceptions in some methods - not good - can break unexpectedly for some users
* Do NOT implement JCache, but use CacheEntryListener interface family and return null from CacheEntryEvent.getSource. Here we don't declare JCache compatibility, but simply use some of the interfaces to make the API similar to Thick. I think this is the most suitable approach, which can be extended to full JCache support in the future.
I guess this warrants a dev list discussion, let me start it.
