feat(cells): add db migration for synapse#109615
Merged
Conversation
this migration replaces the single-column db_index=True on OrganizationMapping.date_updated with a composite expression index on (TruncSecond(date_updated), id), which matches the synapse paginator's order by and where clause. this avoids expensive sequential scans or any additional sorting steps.
