Subject [jira] [Commented] (HDFS-11781) Ozone: KSM: Add deleteKey
Date Thu, 01 Jun 2017 16:54:04 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11781?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16033288#comment-16033288

Anu Engineer commented on HDFS-11781:

bq. I am a bit hesitated on when is the right time to remove the key from KSM database, that
is to say the time a key becomes to be invisible for a client. 

You are absolutely right, we have to handle this in an async fashion, in fact in the Ozone
world, that might be the only option. Just delete the key from KSM for time being and write
that information to another DB -- That is all we need to do for now. We will need a background
thread to take care of these things anyways.
