---------------------------------
Summary: Serialize BitmapCounter with peekLength
Key: KYLIN-2349
URL: https://issues.apache.org/jira/browse/KYLIN-2349
Project: Kylin
Issue Type: Improvement
Components: Metadata
Affects Versions: v1.6.0
Reporter: kangkaisen
Assignee: kangkaisen
Currently, in {{BitmapCounter}} we deserialize the bitmap to get the
peekLength, we know which is expensive in terms of CPU time from JMC hot code.
Actually, we could Serialize {{BitmapCounter}} with peekLength to avoid
deserializing the bitmap when we get peekLength.
Of course, we need to keep forward compatibility.
