Subject [jira] [Created] (HDFS-11920) Ozone : add key partition
Date Fri, 02 Jun 2017 18:32:04 GMT
Chen Liang created HDFS-11920:

             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.
