Summary: Introduce detailed lock information
Key: HDDS-8974
URL: https://issues.apache.org/jira/browse/HDDS-8974
Project: Apache Ozone
Issue Type: Task
Reporter: Janus Chow
Assignee: Janus Chow
In Hadoop fair call queue feature, we can use RPC call's processing details to
provide cost-based scheduler, this information needs the locks' wait, read and
write time.
In Hadoop, these information can be easily get and set via threadLocal
variables, but in Ratis enabled cluster, we can't do that as Hadoop. So this
ticket is to change the lock interface to return a new Class as OMLockDetails
to store this information.
