> Support updates during clustering
> ---------------------------------

> Key: HUDI-1045
> URL: https://issues.apache.org/jira/browse/HUDI-1045
> Project: Apache Hudi
> Issue Type: Task
> Components: clustering, table-service
> Reporter: leesf
> Assignee: Vinoth Chandar
> Priority: Blocker
> Fix For: 1.0.0

>
> h4. We need to allow a writer w writing to file groups f1, f2, f3,
> concurrently while a clustering service C reclusters them into f4, f5.
> Goals
> * Writes can be either updates, deletes or inserts.
> * Either clustering C or the writer W can finish first
> * Both W and C need to be able to complete their actions without much
> redoing of work.
> * The number of output file groups for C can be higher or lower than input
> file groups.
> * Need to work across and be oblivious to whether the writers are operating
> in OCC or NBCC modes
> * Needs to interplay well with cleaning and compaction services.
> h4. Non-goals
> * Strictly the sort order achieved by clustering, in face of updates (e.g
> updates change clustering field values, causing output clustering file groups
> to be not fully sorted by those fields)
