RedisDb

Store AgentOS sessions, memory, knowledge, evals, and traces in Redis.

RedisDb implements the Db interface with Redis key-value storage for Agent, Team, and Workflow sessions, memories, knowledge, metrics, evals, traces, and spans. Records are stored as JSON strings under a configurable key prefix, with optional TTL expiry.

ParameterTypeDefaultDescription
idOptional[str]-Database ID. Derived deterministically from the URL (or client representation) and key prefix when omitted.
redis_clientOptional[Union[Redis, RedisCluster]]-Redis client instance to use. If not provided a new client will be created from db_url. Required for Redis Cluster connections.
db_urlOptional[str]-Redis connection URL (e.g., "redis://localhost:6379/0" or "rediss://user:pass@host:port/db"). Supports single-node Redis only.
db_prefixstr"agno"Prefix for all Redis keys.
expireOptional[int]-TTL for Redis keys in seconds.
session_tableOptional[str]-Name of the table to store sessions.
runs_tableOptional[str]-Name of the table to store runs.
memory_tableOptional[str]-Name of the table to store memories.
metrics_tableOptional[str]-Name of the table to store metrics.
eval_tableOptional[str]-Name of the table to store evaluation runs.
knowledge_tableOptional[str]-Name of the table to store knowledge documents.
traces_tableOptional[str]-Name of the table to store traces.
spans_tableOptional[str]-Name of the table to store spans.

Methods

upsert_sessions

Upsert multiple sessions in one method call.

Parameters:

  • sessions (List[Session]): List of sessions to upsert
  • deserialize (Optional[bool]): Whether to deserialize the sessions. Defaults to True
  • preserve_updated_at (bool): Request preservation of the sessions' existing updated_at timestamps; see adapter limitations below. Defaults to False

Returns: List[Union[Session, Dict[str, Any]]]

upsert_memories

Upsert multiple memories in one method call.

Parameters:

  • memories (List[UserMemory]): List of memories to upsert
  • deserialize (Optional[bool]): Whether to deserialize the memories. Defaults to True
  • preserve_updated_at (bool): Request preservation of the memories' existing updated_at timestamps; see adapter limitations below. Defaults to False

Returns: List[Union[UserMemory, Dict[str, Any]]]

Timestamp preservation by adapter

JsonDb, GcsJsonDb, FirestoreDb, RedisDb, DynamoDb, and InMemoryDb accept preserve_updated_at but do not forward it to their individual upserts. Their bulk methods replace timestamps even when it is True.

PostgresDb, SingleStoreDb, and ValkeyDb honor the flag. MySQLDb, SqliteDb, and MongoDb honor it on their optimized bulk path; their per-record fallback paths do not forward it. Verify timestamps when a migration depends on preserving them.
