Subject [GitHub] drill pull request: DRILL-4275: Refactor e/pstore interfaces and t...

Github user hnfgns commented on the pull request:

    I took the API somewhat Drill internal but you are right about discussing this in the
public list first. This patch -as the numbers above check out- is more of a clean-up than
an extension. My plan was to discuss possible changes to API going forward once this clean-up
patch made its way to master. Here is the rationale: I spent quite a while trying to understand
the current design, event flow in the API in an attempt to find a way for subscribing to store
events. Especially being notified when an ephemeral node dies just like what Zookeeper watches
offer. I got confused multiple times with E/PStore and E/PStoreProvider distinction at interface
level as it seems redundant. That's how the idea of this clean-up patch rolled out. 
    As for naming, I am open for non-abbreviated alternates. I would invite developers relying
on this interface to read the documentation first. To this end, I will go ahead and extend
documentation with possible warning areas. 
    Please let me know if you want me to address specific issues with this patch.
