Work Description: echauchot commented on issue #11055: [BEAM-9436]
Improve GBK in spark structured streaming runner

> Once again, I saw your results (and even mentioned them in my previous
comment) but I asked for more details since it was not clear what kind of tests
have been running and, before, we usually provided Nexmark results in such kind
of optimisations.
My bad, the results comment was not clear enough: when the PR contained the
jenkins scripts of the load tests it was clear but now that I have separated
them in a different PR, it is no more clear: the test that I ran was
`GroupByKeyLoadTest` and the CL:
`-Xms12g -Xmx20g -Prunner=":runners:spark"
-PloadTest.mainClass="org.apache.beam.sdk.loadtests.GroupByKeyLoadTest"
-PloadTest.args="--fanout=1 --iterations=1 --streaming=false
--runner=SparkStructuredStreamingRunner
--sourceOptions={\"numRecords\":200000,\"keySizeBytes\":100000,\"valueSizeBytes\":100000}"`
