Sprint: 0.13.0 Final Sprint 2, 0.13.0 Final Sprint 3 (was: 0.13.0 Final
Sprint 2)
> Optimize Bloom Index lookup DAG
> -------------------------------
>
> Key: HUDI-5534
> URL: https://issues.apache.org/jira/browse/HUDI-5534
> Project: Apache Hudi
> Issue Type: Improvement
> Components: writer-core
> Reporter: Alexey Kudinkin
> Assignee: Alexey Kudinkin
> Priority: Critical
> Labels: pull-request-available
> Fix For: 0.13.0
>
>
> There are some low-hanging performance optimizations that could considerably
> improve performance of the Bloom Index lookup seq:
> # Map file-comparison pairs to PairRDD (where key is file-name, and value is
> record-key) instead of RDD, this would allow us to
> ## Do sorting by filename (to make sure we check all records w/in the file
> all at once) w/in a single Spark partition instead of global one (reducing
> shuffling as well)
> ## Avoid re-shuffling (by re-mapping from RDD to PairRDD later)
