----------------------------------
Assignee: Sam Whittle
> Reduce latency by parallelizing BQ inserts when flushing due to row limit
> -------------------------------------------------------------------------
>
> Key: BEAM-13268
> URL: https://issues.apache.org/jira/browse/BEAM-13268
> Project: Beam
> Issue Type: Improvement
> Components: io-java-gcp
> Reporter: Sam Whittle
> Assignee: Sam Whittle
> Priority: P2
>
> InsertBatchedElements consumes the output of GroupIntoBatches which flushes
> after default 500 elements to respect the max items per streaming insert
> request to BQ.
> However InsertBatchedElements flushes rows synchrounously meaning that
> latencies of writes accumulates. It could instead initiate writes in
> ProcessElement and block on write completion in FinishBundle. There could be
> some limited configurable parallelism if desired to limit memory usage.
