What Redis data types does the NoClick node support?

The node covers strings, hashes, lists, sets, sorted sets, and streams, plus key-level operations like expiration, renaming, scanning, and existence checks. It also supports pub/sub publishing, HyperLogLog, geospatial commands, and bit operations. Each data type has its own group of operations, so you pick the structure that fits your use case.

Can I set keys to expire automatically?

Yes. You can attach a TTL when writing a key using the set-with-expiration operations, or apply expiration to an existing key in seconds or milliseconds. There are also operations to read a key's remaining time-to-live and to fetch its expiry as a Unix timestamp, which makes Redis a natural fit for caches and short-lived session data.

How do I use Redis for caching in a workflow?

A common pattern is to check for a cached value with a GET operation at the start of a workflow; if the key exists, use it and skip the expensive work. If it does not, run the work and write the result with a SET-with-expiration operation so subsequent runs hit the cache. This reduces repeated API calls and database load across workflow executions.

Does the Redis node support transactions and atomic operations?

It does. The node exposes the start-transaction, execute-transaction, and discard operations along with WATCH and UNWATCH for optimistic locking. You can also run Lua scripts and pipeline multiple commands in a single request. Counter operations like increment and decrement are atomic on their own.

Can a workflow read from and write to Redis streams?

Yes. The node can append entries to a stream, read ranges of entries, and work with consumer groups by creating a group, reading from it, and acknowledging processed messages. This supports event-log and message-queue patterns where multiple consumers process a stream cooperatively.

237 operations availableDatabases & Storage

Redis is an in-memory data store used for caching, session storage, rate limiting, queues, leaderboards, and real-time messaging. The NoClick Redis node gives a workflow direct access to that store, covering plain string keys, hashes, lists, sets, sorted sets, streams, pub/sub channels, and key expiration. It supports the data structures Redis is known for, so you can use it as fast shared state between workflow runs rather than reaching for a heavier database. Operations range from a simple GET and SET to sorted-set ranking and stream consumer groups.
