Summary: Support container merging
Key: HDDS-13608
URL: https://issues.apache.org/jira/browse/HDDS-13608
Project: Apache Ozone
Issue Type: Wish
Reporter: Ivan Andika
Assignee: Ivan Andika
In an ideal cluster, each container will be closed when it's full (e.g. nearing
the 5GB size). However, in real clusters a lot of times these containers are
prematurely closed due to one reason or another which causes a lot of small
containers. Small and big containers are considered equally during container
replications which cause things like decommission to take a longer time since
it needs to replicate a lot of these small containers.
This is a wish to kickstart discussion on container merging. If there are small
CLOSED containers, we can schedule some merging to put them as a single
container. However, there are a lot of foreseen complexities since we might
need to create a new container ID which will be different in what is stored in
the key location info in the OM.
