Baohe Zhang updated SPARK-31608:
--------------------------------
Description:
This is a follow-up for the work done by Hieu Huynh in 2019.
Add a new class HybridKVStore to make the history server faster when loading
event files. When writing to this kvstore, it will first write to an in-memory
store and having a background thread that keeps pushing the change to levelDB.
I ran some tests on 3.0.1 on mac os:
||kvstore type / log size||100m||200m||500m||1g||2g||
|HybridKVStore|5s to parse, 7s(include the parsing time) to switch to
leveldb|6s to parse, 10s to switch to leveldb|15s to parse, 23s to switch to
leveldb|23s to parse, 40s to switch to leveldb|37s to parse, 73s to switch to
leveldb|
|LevelDB|12s to parse|19s to parse|43s to parse|69s to parse|124s to parse|
