------------------------------------
Summary: Delete replayed entry from OpenKeyTable during commit
Key: HDDS-2980
URL: https://issues.apache.org/jira/browse/HDDS-2980
Project: Hadoop Distributed Data Store
Issue Type: Sub-task
Reporter: Hanisha Koneru
Assignee: Hanisha Koneru
During KeyCreate (and S3InitiateMultipartUpload), we do not check the
OpenKeyTable if the key already exists. If it does exist and the transaction is
replayed, we just override the key in OpenKeyTable. This is done to avoid extra
DB reads.
During KeyCommit (or S3MultipartUploadCommit), if the key was already
committed, then we do not replay the transaction. This would result in the
OpenKeyTable entry to remain in the DB till it is garbage collected.
To avoid storing stale entries in OpenKeyTable, during commit replays, we
should check the openKeyTable and delete the entry if it exists.
