Summary: Ozone : add key partition
Key: HDFS-11920
URL: https://issues.apache.org/jira/browse/HDFS-11920
Project: Hadoop HDFS
Issue Type: Sub-task
Reporter: Chen Liang
Assignee: Chen Liang
Currently, each key corresponds to one single SCM block, and putKey/getKey
writes/reads to this single SCM block. This works fine for keys with reasonably
small data size. However if the data is too huge, (e.g. not even fits into a
single container), then we need to be able to partition the key data into
multiple blocks, each in one container. This JIRA changes the key-related
classes to support this.
