When opening a group chat we check if all participants are verified (which confers to the chat verified status and a "✓ Verified" label in the header) and we also check if any participants have the "no longer verified" status so we can warn you about potential misdeeds. Previously, this was done by performing a select statement for each participant twice (once for "are all verified" and again for "is any no-longer-verified"). This change uses a join in a select statement instead to reduce the number of queries performed. Given existing indexes in the DB this can be done efficiently. Adding additional indexes does not seem to help - or at least I wasn't able to get sqlite to use them. Since most chats are not verified, we use a LIMIT clause when possible to allow the DB to stop early, which should make queries even cheaper. |
