Prior to this commit we would essentially update all rows in a table, even those where the source column (e.g. `issues.closed_at`) was NULL. This in turn could lead to statement timeouts when using the default batch size of 10 000 rows per job. To work around this we don't schedule jobs for rows where the source value is NULL. We also don't update rows where the source column is NULL (as an extra precaution) or the target column already has a non-NULL value. Using this approach it should be possible to update 10 000 rows in the "issues" table in about 7.5 - 8 seconds. Fixes https://gitlab.com/gitlab-org/gitlab-ce/issues/42158 |
