kangkaisen created KYLIN-2349: --------------------------------- 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
