Review Request 14578: [HELIX-268] Atomic API

Review request for helix, Zhen Zhang and Kishore Gopalakrishna.


Bugs: HELIX-268


Repository: helix-git


Description
-------

This is still on the helix-logical-model branch, but I thought I would create a review to increase readability. Here is an implementation of atomic accessors by way of locks. It uses the ZooKeeper lock recipe as its underlying implementation.


Diffs
-----

Diff: https://reviews.apache.org/r/14578/diff/


Testing
-------

Wrote and ran the tests included in this review. Locking/blocking and recreation appear to work correctly based on these tests.


Thanks,

Kanak Biscuitwala

Looks fantastic, love the concept of locks at various granularities. I havent looked at the details on implementation but the API is amazing. Make sure Jason reviews the implementation and failure cases. Provide a warning that its expensive to use AtomicAccessor and should be used sparingly and with care
