reivilibre	66a5f6c400	Add a unique index to state_group_edges to prevent duplicates being accidentally introduced and the consequential impact to performance. (#12687)	2022-05-19 14:16:49 +01:00
Erik Johnston	3acf85c85f	Reduce likelihood of Postgres table scanning state_groups_state. (#10359) ... The postgres statistics collector sometimes massively underestimates the number of distinct state groups are in the `state_groups_state`, which can cause postgres to use table scans for queries for multiple state groups. We fix this by manually setting `n_distinct` on the column.	2021-07-15 16:02:12 +01:00
Richard van der Hoff	25f43faa70	Reorganise the database schema directories (#9932) ... The hope here is that by moving all the schema files into synapse/storage/schema, it gets a bit easier for newcomers to navigate. It certainly got easier for me to write a helpful README. There's more to do on that front, but I'll follow up with other PRs for that.	2021-05-07 10:22:05 +01:00
