Research direction
Review issue #3777 and the linked pull-request comment first, then inspect the repository's existing test and CI layout to find the timing-test location. Done means adding a CI timing regression test for many .SD columns, keeping the CRAN correctness suite quick, and documenting a reproducible example for r-devel if the root cause is followed up.
Written by the indexing model from the issue text.
Description
-
Follow up to #3777. Add a test in CI somewhere to ensure it doesn't come back. I almost added it to the main test suite but didn't since we need a timing test suite anyway, and the main test suite running on CRAN should be correctness only and quick.
-
also follow up on the root cause and make a reproducible example for r-devel. See "Next step would be ..." at the bottom of this comment : https://github.com/Rdatatable/data.table/pull/3777#issuecomment-525965669
