Add a data migration to remove existing duplicates of DastSiteTokens
What does this MR do?
This merge request adds a data migration to remove the existing duplicates of DastSiteToken with the same URL and project.
The data migration is a regular migration because:
- this is a low traffic feature with 371 rows in the
dast_site_tokens
table ongitlab.com
. - it should be fast. It currently runs in 1.4s
- To make sure that
RemoveDuplicateDastSiteTokens
has run before before we run the follow-up MR. The follow-up merge request to this one will be one that adds a unique index.
This MR is responsible for the following tasks required for issue #338188 (closed).
add a data migration to remove existing duplicates
add a migration that adds a composite index (project_id, url)
Raw SQL to find the DastSiteToken with duplications:
SELECT DISTINCT
array_agg(id) AS ids
FROM
"dast_site_tokens"
GROUP BY
"dast_site_tokens"."project_id",
"dast_site_tokens"."url"
HAVING (count(*) > 1)
Time: 0.624 ms
Migration execution time = 1.4s
