-------------------------------------
Assignee: Ali Anwar (was: Poorna Chandra)
> Flushes and compactions can remove committed data
> -------------------------------------------------
>
> Key: TEPHRA-235
> URL: https://issues.apache.org/jira/browse/TEPHRA-235
> Project: Tephra
> Issue Type: Bug
> Components: core
> Affects Versions: 0.11.0-incubating, 0.12.0-incubating
> Reporter: Poorna Chandra
> Assignee: Ali Anwar
> Priority: Blocker
> Fix For: 0.13.0-incubating
>
>
> Transaction co-processor uses the transaction snapshot generated by the
> Transaction Manager to remove deleted and invalid cells during HBase
> compactions and flushes. The co-processor expects the invalid list in the
> transaction snapshot to be sorted. However, the invalid list is not sorted
> during a snapshot creation in the Transaction Manager. This leads to invalid
> transactions becoming visible during compactions, and thus committed
> transactions with write pointers smaller than the invalid transaction will
> get removed.
> We missed this piece when fixing TEPHRA-223.
