Anu Engineer commented on HDFS-11601:
-------------------------------------
[~cheersyang] With the new scale that we have seen, more than 3 million keys,
do you know if this is an issue? or do we much larger numbers? say 10 million
ozone keys?
> Ozone: Compact DB should be called on Open Containers.

> Key: HDFS-11601
> URL: https://issues.apache.org/jira/browse/HDFS-11601
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: ozone
> Affects Versions: HDFS-7240
> Reporter: Anu Engineer
> Assignee: Weiwei Yang

> The discussion in HDFS-11594 pointed to a potential issue that we might run
> into. That is too many delete key operations can take place and make a DB
> slow. Running compactDB in those cases are useful. Currently we run compactDB
> when we close a container. This JIRA tracks a potential improvement of
> running compactDB even on open containers.
