simplebroker-redis

Valkey/Redis backend extension for SimpleBroker.

This package exposes the public SimpleBroker backend name redis. It targets Valkey 7.x and Redis 7.x and the test suite runs against Valkey.

Requirements

  • Python 3.11+
  • Valkey 7.x or Redis 7.x

Durability depends on the server configuration. A Valkey or Redis deployment without AOF/RDB persistence can lose messages on restart. Use SQLite or Postgres when you need storage durability from the broker stack by default.

Regular broker commands use a redis-py BlockingConnectionPool owned by the process-local Redis runner. Pub/Sub wake hints use a separate dedicated connection because subscribed Redis connections cannot serve normal commands.

Pool defaults:

  • max_connections = 50
  • pool_timeout = BROKER_BUSY_TIMEOUT / 1000

The defaults can be overridden in project backend options:

[backend_options]
namespace = "simplebroker_redis_v1"
max_connections = 50
pool_timeout = 5.0

Pool exhaustion is bounded by pool_timeout and surfaces as an operational error from broker operations.

Concurrency semantics

Queue deletion is atomic per queue. delete() first snapshots the queue registry, then one Lua invocation per selected queue rechecks active at-least-once reservations and removes that queue's pending, claimed, body, and global-ID state together. A queue created after the registry snapshot is outside the operation and is not deleted. If a reservation starts between per-queue invocations, deletion stops with an error; queues already processed remain deleted, while that reserved queue and later queues remain intact.

Patternless broadcast() selects the current queue registry and inserts every copy in one Lua invocation. A queue cannot be missed or resurrected by a concurrent write or deletion that commits before that invocation. Activity notifications and maintenance accounting run after the atomic insert commits.

Exact-target broadcast(..., queue_names=...) also intersects the requested literal names with the registry and inserts all copies in one Lua invocation. Missing names are ignored and not created. A requested queue deleted before the script selects targets is not resurrected; an all-missing request returns zero without advancing persisted last_ts, publishing wakeups, or scheduling maintenance.

Patterned broadcasts deliberately keep a client-side queue snapshot so their matching stays exactly Python fnmatchcase syntax. A queue created after the snapshot can miss that broadcast; a queue deleted after the snapshot can be recreated by it. Use a patternless or exact-target broadcast when atomic registry selection is required.

Exact-target broadcast requires backend API v4: SimpleBroker 5.6.0 or newer and simplebroker-redis 3.3.0 or newer.
