From 3d9f82efcb9c337197c9f50a88ec3fb541ee08ff Mon Sep 17 00:00:00 2001 From: Patrick Cloke Date: Fri, 9 Sep 2022 07:08:41 -0400 Subject: [PATCH] Use an upsert for `receipts_graph`. (#13752) Instead of a delete, then insert. This was previously done for `receipts_linearized` in 2dc430d36ef793b38d6d79ec8db4ea60588df2ee (#7607). --- changelog.d/13752.misc | 1 + synapse/storage/databases/main/receipts.py | 12 ++++-------- 2 files changed, 5 insertions(+), 8 deletions(-) create mode 100644 changelog.d/13752.misc diff --git a/changelog.d/13752.misc b/changelog.d/13752.misc new file mode 100644 index 000000000..7624861b9 --- /dev/null +++ b/changelog.d/13752.misc @@ -0,0 +1 @@ +User an additional database query when persisting receipts. diff --git a/synapse/storage/databases/main/receipts.py b/synapse/storage/databases/main/receipts.py index 124c70ad3..383840951 100644 --- a/synapse/storage/databases/main/receipts.py +++ b/synapse/storage/databases/main/receipts.py @@ -812,7 +812,7 @@ class ReceiptsWorkerStore(SQLBaseStore): # FIXME: This shouldn't invalidate the whole cache txn.call_after(self._get_linearized_receipts_for_room.invalidate, (room_id,)) - self.db_pool.simple_delete_txn( + self.db_pool.simple_upsert_txn( txn, table="receipts_graph", keyvalues={ @@ -820,17 +820,13 @@ class ReceiptsWorkerStore(SQLBaseStore): "receipt_type": receipt_type, "user_id": user_id, }, - ) - self.db_pool.simple_insert_txn( - txn, - table="receipts_graph", values={ - "room_id": room_id, - "receipt_type": receipt_type, - "user_id": user_id, "event_ids": json_encoder.encode(event_ids), "data": json_encoder.encode(data), }, + # receipts_graph has a unique constraint on + # (user_id, room_id, receipt_type), so no need to lock + lock=False, )
