Next Up walked every series in an unpaginated loop and read user data one
episode at a time, so the Home screen row cost two queries per series once the
cache was gone.
- read the played state of every candidate episode in one query
- read the versions the resume check and the last played date need in one query each
- default PrefetchedUserData on IUserBaseItemComparer so plugin comparers still compile
- cover the bounded query count and the plugin comparer with tests
- share one database across the replica tests
The user data cache and the item's in-memory rows were both filled once per
replica and never invalidated, so a pod serving a playback tick read its own
stale resume position and wrote it back over the position another pod had just
saved, silently losing resume points, played state, favourites and ratings.
- drop the user item data cache
- read single and batched user data from the database on every query
- prefetch user data for in-memory sorts and filters so each stays one query
- cover the lost update against real PostgreSQL with two manager instances
The startup configuration only reads JELLYFIN_ prefixed environment
variables, so the bare Jellyfin__TranscodeStore__* form used by the chart,
the manifests and the README is dropped and the Redis store is never
registered. Nothing logs the selected store, so the fallback is invisible.
- Read bare Jellyfin__* variables into the Jellyfin:* configuration root
- Keep an explicit JELLYFIN_ variable winning over the bare form
- Log the selected transcode session store at startup
- Ping Redis once at startup and log an unreachable store at Error
- Log endpoints only, never the connection string
The device cache was filled once at construction, so a token minted by one
replica was unknown to every other replica already running and a token revoked
on one replica stayed valid on the others until they restarted.
- drop the eager device and device options dictionaries
- read devices and device options from the database on every query
- push the device query filters and ordering into SQL
- open the request's database context only for the api key fallback
- cover both directions against real PostgreSQL with two manager instances
Cleanup never matched a live session because the controller registered empty
manifest and segment paths, renewal was a read-modify-write that could revert a
takeover, and the takeover script compared an ISO date to a number, so it errored.
- populate the session record's manifest and segment paths from the playlist path
- renew the lease via a Lua compare-and-set on the owning pod
- store the lease expiry as unix milliseconds so the scripts can compare it
- retain the session record past its lease so an orphan can still be taken over
- test the Redis store against a real Redis, including the renew-vs-takeover race
- drop the live stream record nothing ever read back
Timer-driven library tasks fire on every replica, so a library refresh or a
database optimise runs once per pod against the same shared library.
- add IScanLeaderLease with a Redis TTL implementation and a no-op default
- skip timer-driven runs of the gated tasks on instances without the lease
- treat an unreachable Redis as holding the lease so tasks never stop running
- leave manual and API-triggered runs ungated
Live stream ownership is only tracked in process memory, so no replica can tell
which pod holds a stream open once that pod is gone.
- persist a LiveStreamSession record when the live stream mappings change
- delete the record when the stream is closed
- keep closing the stream when the store is unreachable
Every replica runs the transcode cleanup task against the same shared transcode
directory, so one pod deletes segments another pod is still streaming.
- read the active sessions from ITranscodeSessionStore before deleting
- keep files matching an active session manifest path or segment prefix
- abort the sweep when the store cannot be reached
Transcode state lives only in the process that started ffmpeg, so a pod restart
drops every in-flight HLS stream with no way for a peer to pick it up.
- add ITranscodeSessionStore plus the TranscodeSession and LiveStreamSession records
- add RedisTranscodeSessionStore with TTL leases and an atomic Lua takeover script
- add NullTranscodeSessionStore for single-instance deployments
- pick the store from Jellyfin:TranscodeStore:RedisConnectionString at startup
