Sending out push to a user's device; and + 2. Tracking per-room per-user notification counts (used in sync requests). + +For the former we simply use the `event_push_actions` table, which contains all +the calculated actions for a given user (which were calculated by the +`BulkPushRuleEvaluator`). + +For the latter we could simply count the number of rows in `event_push_actions` +table for a given room/user, but in practice this is *very* heavyweight when +there were a large number of notifications (due to e.g. the user never reading a +room). Plus, keeping all push actions indefinitely uses a lot of disk space. + +To fix these issues, we add a new table `event_push_summary` that tracks +per-user per-room counts of all notifications that happened before a stream +ordering S. Thus, to get the notification count for a user / room we can simply +query a single row in `event_push_summary` and count the number of rows in +`event_push_actions` with a stream ordering larger than S (and as long as S is +"recent", the number of rows needing to be scanned will be small). + +The `event_push_summary` table is updated via a background job that periodically +chooses a new stream ordering S' (usually the latest stream ordering), counts +all notifications in `event_push_actions` between the existing S and S', and +adds them to the existing counts in `event_push_summary`. + +This allows us to delete old rows from `event_push_actions` once those rows have +been counted and added to `event_push_summary` (we call this process +"rotation"). + + +We need to handle when a user sends a read receipt to the room. Again this is +done as a background process. For each receipt we clear the row in +`event_push_summary` and count the number of notifications in +`event_push_actions` that happened after the receipt but before S, and insert +that count into `event_push_summary` (If the receipt happened *after* S then we +simply clear the `event_push_summary`.) + +Note that its possible that if the read receipt is for an old event the relevant +`event_push_actions` rows will have been rotated and we get the wrong count +(it'll be too low). We accept this as a rare edge case that is unlikely to +impact the user much (since the vast majority of read receipts will be for the +latest event). + +The last complication is to handle the race where we request the notifications +counts after a user sends a read receipt into the room, but *before* the +background update handles the receipt (without any special handling the counts +would be outdated). We fix this by including in `event_push_summary` the read +receipt we used when updating `event_push_summary`, and every time we query the +table we check if that matches the most recent read receipt in the room. If yes, +continue as above, if not we simply query the `event_push_actions` table +directly. + +Since read receipts are almost always for recent events, scanning the +`event_push_actions` table in this case is unlikely to be a problem.
