bitblender commented on issue #1335: DRILL-6529: Project Batch Sizing causes
two LargeFileCompilation tests to timeout
URL: https://github.com/apache/drill/pull/1335#issuecomment-400823880
@vvysotskyi @ilooner NUM_PROJECT_COLUMNS controls 3 other tests besides
testTopN and testExternalSort - testPARQUET_WRITER(), testTEXT_Writer and
TestProject. How about we set NUM_PROJECT_COLUMNS=2500 and then introduce a
new constant NUM_PROJECT_TEST_COLUMNS=10000 for testProject? Basically, reduce
the stress on SORTers and WRITERs but bump up the column count on testProject
to a number which will push the code generated for Project over the constant
pool limit. testProject takes about 130s on my Mac with 10000 columns.

> Timeout failures are seen in TestLargeFileCompilation testExternal_Sort and
> testTop_N_Sort. These tests are stress tests for compilation where the
> queries cover projections over 5000 columns and sort over 500 columns. These
> tests pass if they are run stand-alone. Something triggers the timeouts when
> the tests are run in parallel as part of a unit test run.
