> Key: OMID-146
> URL: https://issues.apache.org/jira/browse/OMID-146
> Project: Apache Omid
> Issue Type: Bug
> Reporter: Ohad Shacham
> Assignee: Yonatan Gottesman
> Priority: Minor
> Fix For: 1.0.1
>
>
> When a transaction t updates the conflict table at the TSO, it mights remove
> entries of transactions that committed after t started, or even entries of t.
> Therefore, in order to make sure that the garbage collector does not removes
> entries of t from the data tables, thinking accidentally that t was not
> committed yet. We should first persist t's commit in the commit table and
> only then update the low watermark. This also applies to the low latency
> which persists the commit by the clients.
