Hi All,
[ I apologize if someone got multiple copies of this email! As I got rejections
due to initial email size.]
In continuation to our great talk yesterday (where we agreed about publishing a
PR for Oak Incremental Index for Druid), hereby please find some reading
material about Oak. The pool request itself will be ready for tomorrow. I would
strongly suggest to read some of the documentation prior to looking on the
code, as it may make the last task easier and clearer. As I said the Oak is now
an open source library (yahoo/Oak) and its README might help you to understand
the Oak's interface and new Druid's code.

Recall we had an issue#5698 about Oak Incremental Index
(https://github.com/apache/incubator-druid/issues/5698) and there you can find
another useful documents to start from. We will publish the latest
single-thread ingestion benchmark results tomorrow, together with the pool
request. Feel free to ask questions!
