python
close_all_cached_connections() -> None

Close all cached Redis connections.

python
clear_cached_clients() -> None

Clear all cached Redis clients to force fresh connections.

This should be called when a connection error is detected to ensure subsequent calls to get_async_redis_client() return fresh clients rather than stale ones with broken connections.

python
get_async_redis_client(url: Union[str, None] = None, host: Union[str, None] = None, port: Union[int, None] = None, db: Union[int, None] = None, password: Union[str, None] = None, username: Union[str, None] = None, health_check_interval: Union[int, None] = None, decode_responses: bool = True, ssl: Union[bool, None] = None) -> Redis

Retrieves an async Redis client.

When url is provided (or configured via PREFECT_REDIS_MESSAGING_URL), Redis.from_url is used and the discrete host/port/… arguments are ignored.

Args:

  • url: Full Redis URL (e.g. redis\://localhost\:6379/0).
  • host: The host location.
  • port: The port to connect to the host with.
  • db: The Redis database to interact with.
  • password: The password for the redis host
  • username: Username for the redis instance
  • health_check_interval: Health check interval in seconds.
  • decode_responses: Whether to decode binary responses from Redis to unicode strings.
  • ssl: Whether to use SSL for the connection.

Returns:

  • a Redis client

Settings for connecting to Redis.

Connection can be configured either via a single url field (e.g. redis://user:pass@host:6379/0) or with the individual host/port/db/… fields. When url is set it takes precedence and the discrete fields are ignored.
