Summary: Ozone: SCM: avoid synchronously loading all the keys from
containers upon SCM datanode start
Key: HDFS-12651
URL: https://issues.apache.org/jira/browse/HDFS-12651
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: HDFS-7240
Reporter: Xiaoyu Yao
Assignee: Xiaoyu Yao
This is based on code review feedback from HDFS-12411 to avoid slow SCM
datanode restart when there are large amount of keys and containers.
E.g., 5 GB per container / 4 KB per key = 1.25 Million keys per container.
The proposed solution is async loading containers/key size info and update the
containerStatus once done.
