…ty_id Index UPPER(vulnerability_id), finding_id on dojo_vulnerability_id so CVE-keyed lookups (enrichment, exploit/threat-intel matching, dedupe helpers) stop sequentially scanning the table; scanner-supplied ids are not case-normalized, so the index and any query both fold with UPPER(). finding_id is included so changed-CVE -> finding fan-out is an index-only scan. Built CONCURRENTLY IF NOT EXISTS (non-atomic migration) via SeparateDatabaseAndState so it does not lock the table on large instances and is idempotent.

Add a case-insensitive expression index on
Vulnerability_Id.vulnerability_idAdds an index on
UPPER(vulnerability_id), finding_idtodojo_vulnerability_id.Why
Vulnerability-id → finding lookups (CVE-keyed enrichment, exploit/threat-intel matching, dedupe helpers) currently sequentially scan
dojo_vulnerability_id— the string column has no index today, and scanner-supplied ids aren't case-normalized, so any correct lookup must fold withUPPER(). This adds the matching functional index; includingfinding_idmakes the changed-CVE → finding fan-out an index-only scan.What
Vulnerability_Id.Meta.indexesgainsIndex(Upper("vulnerability_id"), "finding", name="dojo_vulnid_upper_idx").0278builds itCREATE INDEX CONCURRENTLY IF NOT EXISTS(non-atomic) so it doesn't lock the table on large instances, withSeparateDatabaseAndStatekeeping Django's model state in sync.IF NOT EXISTSmakes it idempotent and safe to co-exist with any downstream migration that created the same-named index first.Notes
