Finalize conversion to bigint for ci_build_trace_chunks (!66123) · Merge requests · GitLab.org / GitLab

Krasimir Angelov requested to merge 328443-finalize-ci-build-trace-chunks-bigint-conversion into master Jul 14, 2021

What does this MR do?

This MR finalize the conversion to bigint for ci_build_trace_chunks table.

At a high level, the operation takes the following steps:

Ensure the migration of build_id to bigint is completed.
Copy index and FK
Swap columns

Cleanup (removing the old int columns and the triggers) will be done in later MR.

Related to #328443 (closed).
