> Avoid isCellTTLExpired() for NO-TAG cases

> Key: HBASE-13579
> URL: https://issues.apache.org/jira/browse/HBASE-13579
> Project: HBase
> Issue Type: Sub-task
> Components: Scanners
> Affects Versions: 2.0.0
> Reporter: ramkrishna.s.vasudevan
> Assignee: ramkrishna.s.vasudevan
> Attachments: HBASE-13579_KVExtension.patch,

>
> As observed in this JIRA's performance test, we are always calling the
> isCellTTLExpired() for every cell and internally it is parsing the keyLength,
> valueLength() to get the tagsLength after which we decide whether Cell level
> TTL is present are not.
> This JIRA aims to avoid this check if all the readers of the storescanner
> knows that there are no tags to read. Note that, for the memstore scanner we
> will do that in another JIRA, which I suppose Stack had already raised to
> avoid tag length while flushing (for the NO-TAG) case.
