Summary: Speed up container set loading during Datanode Startup
Key: HDDS-12391
URL: https://issues.apache.org/jira/browse/HDDS-12391
Project: Apache Ozone
Issue Type: Improvement
Components: Ozone Datanode
Reporter: Ivan Andika
We found that DN startup took very long to send the first heartbeat to the SCM,
causing SCM to think the DN is STALE and DEAD.
Seems DN takes very long to read all the container files in ContainerReader, it
takes approximately 30 minutes. We should try to optimize this (maybe need to
support merging containers).
