Would it make sense to add the cache_name as a label?
There was a problem hiding this comment.
I don't think so, the times shouldn't depend on what we're caching (and I'm a bit cautious about the fact it adds a bunch of extra metrics). Broadly these should be super quick, and if they're not then something is wrong/congested.

Synapse 1.34.0 (2021-05-17) =========================== This release deprecates the `room_invite_state_types` configuration setting. See the [upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.34.0/UPGRADE.rst#upgrading-to-v1340) for instructions on updating your configuration file to use the new `room_prejoin_state` setting. This release also deprecates the `POST /_synapse/admin/v1/rooms/<room_id>/delete` admin API route. Server administrators are encouraged to update their scripts to use the new `DELETE /_synapse/admin/v1/rooms/<room_id>` route instead. No significant changes since v1.34.0rc1. Synapse 1.34.0rc1 (2021-05-12) ============================== Features -------- - Add experimental option to track memory usage of the caches. ([\matrix-org#9881](matrix-org#9881)) - Add support for `DELETE /_synapse/admin/v1/rooms/<room_id>`. ([\matrix-org#9889](matrix-org#9889)) - Add limits to how often Synapse will GC, ensuring that large servers do not end up GC thrashing if `gc_thresholds` has not been correctly set. ([\matrix-org#9902](matrix-org#9902)) - Improve performance of sending events for worker-based deployments using Redis. ([\matrix-org#9905](matrix-org#9905), [\matrix-org#9950](matrix-org#9950), [\matrix-org#9951](matrix-org#9951)) - Improve performance after joining a large room when presence is enabled. ([\matrix-org#9910](matrix-org#9910), [\matrix-org#9916](matrix-org#9916)) - Support stable identifiers for [MSC1772](matrix-org/matrix-spec-proposals#1772) Spaces. `m.space.child` events will now be taken into account when populating the experimental spaces summary response. Please see [the upgrade notes](https://github.com/matrix-org/synapse/blob/release-v1.34.0/UPGRADE.rst#upgrading-to-v1340) if you have customised `room_invite_state_types` in your configuration. ([\matrix-org#9915](matrix-org#9915), [\matrix-org#9966](matrix-org#9966)) - Improve performance of backfilling in large rooms. ([\matrix-org#9935](matrix-org#9935)) - Add a config option to allow you to prevent device display names from being shared over federation. Contributed by @aaronraimist. ([\matrix-org#9945](matrix-org#9945)) - Update support for [MSC2946](matrix-org/matrix-spec-proposals#2946): Spaces Summary. ([\matrix-org#9947](matrix-org#9947), [\matrix-org#9954](matrix-org#9954)) Bugfixes -------- - Fix a bug introduced in v1.32.0 where the associated connection was improperly logged for SQL logging statements. ([\matrix-org#9895](matrix-org#9895)) - Correct the type hint for the `user_may_create_room_alias` method of spam checkers. It is provided a `RoomAlias`, not a `str`. ([\matrix-org#9896](matrix-org#9896)) - Fix bug where user directory could get out of sync if room visibility and membership changed in quick succession. ([\matrix-org#9910](matrix-org#9910)) - Include the `origin_server_ts` property in the experimental [MSC2946](matrix-org/matrix-spec-proposals#2946) support to allow clients to properly sort rooms. ([\matrix-org#9928](matrix-org#9928)) - Fix bugs introduced in v1.23.0 which made the PostgreSQL port script fail when run with a newly-created SQLite database. ([\matrix-org#9930](matrix-org#9930)) - Fix a bug introduced in Synapse 1.29.0 which caused `m.room_key_request` to-device messages sent from one user to another to be dropped. ([\matrix-org#9961](matrix-org#9961), [\matrix-org#9965](matrix-org#9965)) - Fix a bug introduced in v1.27.0 preventing users and appservices exempt from ratelimiting from creating rooms with many invitees. ([\matrix-org#9968](matrix-org#9968)) Updates to the Docker image --------------------------- - Add `startup_delay` to docker healthcheck to reduce waiting time for coming online and update the documentation with extra options. Contributed by @maquis196. ([\matrix-org#9913](matrix-org#9913)) Improved Documentation ---------------------- - Add `port` argument to the Postgres database sample config section. ([\matrix-org#9911](matrix-org#9911)) Deprecations and Removals ------------------------- - Mark as deprecated `POST /_synapse/admin/v1/rooms/<room_id>/delete`. ([\matrix-org#9889](matrix-org#9889)) Internal Changes ---------------- - Reduce the length of Synapse's access tokens. ([\matrix-org#5588](matrix-org#5588)) - Export jemalloc stats to Prometheus if it is being used. ([\matrix-org#9882](matrix-org#9882)) - Add type hints to presence handler. ([\matrix-org#9885](matrix-org#9885)) - Reduce memory usage of the LRU caches. ([\matrix-org#9886](matrix-org#9886)) - Add type hints to the `synapse.handlers` module. ([\matrix-org#9896](matrix-org#9896)) - Time response time for external cache requests. ([\matrix-org#9904](matrix-org#9904)) - Minor fixes to the `make_full_schema.sh` script. ([\matrix-org#9931](matrix-org#9931)) - Move database schema files into a common directory. ([\matrix-org#9932](matrix-org#9932)) - Add debug logging for lost/delayed to-device messages. ([\matrix-org#9959](matrix-org#9959))
