Lokesh Jain commented on HDFS-12537: ------------------------------------ [~nandakumar131] [~anu] Thanks for reviewing the patch. Currently the default behavior adds a random UUID in each key value. I think the optimizedWrites option can be removed. If it would be removed there would be two writes made to the outputStream, the option does it in a single write. But it is not much of an overhead. So it can be removed. > Ozone: Reduce key creation overhead in Corona > --------------------------------------------- > > Key: HDFS-12537 > URL: https://issues.apache.org/jira/browse/HDFS-12537 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Lokesh Jain > Assignee: Lokesh Jain > Attachments: HDFS-12537-HDFS-7240.001.patch, > HDFS-12537-HDFS-7240.002.patch > > > Currently Corona creates random key values for each key.
