[jira] [Created] (JAMES-3765) Massive operations on some IMAP command are slow
Tran Hong Quan created JAMES-3765:
-------------------------------------
Summary: Massive operations on some IMAP command are slow
Key: JAMES-3765
URL: https://issues.apache.org/jira/browse/JAMES-3765
Project: James Server
Issue Type: Improvement
Reporter: Tran Hong Quan
Attachments: 68747470733a2f2f696d616765732e7a656e68756275736572636f6e74656e742e636f6d2f3566376665336238623637613735366537633633643138312f31366361643337322d666133662d343731372d396438632d373437653336363163336361.png
These IMAP commands are slow when running against a big messages number:
* IMAP Store
* IMAP Copy
* IMAP Move
This could be improved by:
* Change sequential handling -> concurrent handling (with Cassandra consistency condition)
* Increase copy and move batch size in `batchsize.properties`
Also, RENAME command has a consistency issue. We should consider using concatMap for it.
