> `ClusteringCommitSink` could strengthen commit and rollback strategy from two
> solutions:
> * Commit: Introduces `clusteringPlanCache` that caches to store clustering
> plan for each instant. `clusteringPlanCache` stores the mapping of
> instant_time -> clusteringPlan.
> * Rolback: Updates `commitBuffer` that stores the mapping of instant_time ->
> file_ids -> event. Use a map to collect the events because the rolling back
> of intermediate clustering tasks generates corrupt events.
