Dan Smith updated GEODE-6148:
-----------------------------
Sprint: Current Iteration 5
> Improve the efficiency of PrePopulateRegion and increase the key range
> ----------------------------------------------------------------------
>
> Key: GEODE-6148
> URL: https://issues.apache.org/jira/browse/GEODE-6148
> Project: Geode
> Issue Type: Improvement
> Components: benchmarks
> Reporter: Dan Smith
> Assignee: Helena Bales
> Priority: Major
> Labels: pull-request-available
>
> We are currently running with a keyRange of 1000, which may be skewing our
> results. We want to run with a much larger key range, which means
> prepopulating more data.
> The PrePopulateRegion task could be much faster if we take some of these
> steps:
> * Stop duplicating work - right now each server will put the entire key
> range, resulting in duplicate puts of the same keys
> * use multiple threads - each server populating the region could be using
> multiple threads to populate it faster. One option would be to use a
> parallelStream, there may be better choicse.
> * Use putAlls - putAlls in batches require fewer round trips than puts.
> Acceptance:
> * All benchmarks can finish their prepopulation step in 30 seconds or less on
> reasonable hardware.
> * We set a fixed key range that is somewhere between 100 thousand and 100
> million, whatever is most reasonable.
