Redis

Schlüssel-Wert-Operationen mit Redis

Redis is an open-source, in-memory data structure store, used as a distributed key-value database, cache, and message broker. Redis supports a variety of data structures including strings, hashes, lists, sets, and more, making it highly flexible for different application scenarios.

With Redis, you can:

Store and retrieve key-value data instantly: Use Redis as a fast database, cache, or session store for high performance.
Work with multiple data structures: Manage not just strings, but also lists, hashes, sets, sorted sets, streams, and bitmaps.
Perform atomic operations: Safely manipulate data using atomic commands and transactions.
Support pub/sub messaging: Use Redis’s publisher/subscriber features for real-time event handling and messaging.
Set automatic expiration policies: Assign TTLs to keys for caching and time-sensitive data.
Scale horizontally: Use Redis Cluster for sharding, high availability, and scalable workloads.

In AACFlow, the Redis integration lets your agents connect to any Redis-compatible instance to perform key-value, hash, list, and utility operations. You can build workflows that involve storing, retrieving, or manipulating data in Redis, or manage your app’s cache, sessions, or real-time messaging, directly within your AACFlow workspace.
