[incubator-pinot] 03/07: split out main logic of kc to different
classes, added unit tests
This is an automated email from the ASF dual-hosted git repository.
jamesshao pushed a commit to branch upsert
in repository https://gitbox.apache.org/repos/asf/incubator-pinot.git
commit 2ed3218a80cd0d7766955f3adf58fee3156d03b3
Author: james Shao <sj...@uber.com>
AuthorDate: Tue Dec 17 14:55:42 2019 -0800
split out main logic of kc to different classes, added unit tests
Summary:
split out the main logic of key coordinator core to 3 different classes to make testing/future changes easier
1. MessageFetcher: handle logics of fetching messages from kafka and storing internally
2. SegmentEventProcessor: handle logics of processing update events from coming in to sending updates out, storing on disk, etc
3. VersionMessageManager: handle emitting version message and storing current version messages
