jobs: enable jobs.avoid_full_scans.enabled by default

mgartner · mgartner · commit f5c864b95927 · 2025-04-14T08:15:42.000-06:00
Release note (performance improvement): Some internal queries executed
by the jobs system are now less likely to perform full table scans of
the `system.jobs` table, making them more efficient. This change can be
reverted by disabling the
`jobs.avoid_full_scans_in_find_running_jobs.enabled` cluster setting.
