> Key: HUDI-845
> URL: https://issues.apache.org/jira/browse/HUDI-845
> Project: Apache Hudi
> Issue Type: Improvement
> Components: Writer Core
> Reporter: Vinoth Chandar
> Assignee: Nishith Agarwal
> Priority: Blocker
> Labels: help-requested
> Fix For: 0.7.0
>
>
> Things to think about
> * Commit time has to be unique across writers
> * Parallel writers can finish commits out of order i.e c2 commits before c1.
> * MOR log blocks fence uncommited data..
> * Cleaner should loudly complain if it cannot finish cleaning up partial
> writes.
> * Move the pending rollback work into cleaner
>
> P.S: think about what is left for the general thing : log files may have
> different order, inserts may violate uniqueness constraint
