> Key: HBASE-11315
> URL: https://issues.apache.org/jira/browse/HBASE-11315
> Project: HBase
> Issue Type: Improvement
> Affects Versions: 0.99.0
> Reporter: Jeffrey Zhong
> Assignee: Jeffrey Zhong
> Attachments: hbase-11315-v1.patch, hbase-11315.patch
>
>
> After hbase-8763, we need keep mvcc number longer in hfile so that it can be
> used to order changes during writes. For example, the known
> put,delete,put,... scenario, cross region server scan, out of order puts(in
> recovery case).
> Current thinking is that we make the retention period configurable(below
> we're using 1 day to explain). During major compaction, we check hfile's
> creation time if a hfile creation time is older than 1 day then all mvcc of
> KVs in that hfile will be removed. If a hfile is created within 1 day, then
> all mvccs of KVs in that hfile will be kept.
> In case there are time clock skew, we can firstly sort hfiles based on its
> seqId in ascending order and find the first hfile's creation time stamp less
> than 1 day. Then mvcc of all hfiles before the found file will be removed
> during compaction.
