We are also gradually adding changes introduced in later versions. Most of the unsupported items are in our roadmap. If you need a feature that we do not support, please drop a note to [support@upstash.com](mailto:support@upstash.com). So we can inform you when we are planning to support it. *** ## Supported Commands Count set bits in a string Perform arbitrary bitfield operations Read-only bitfield operations Perform bitwise operations between strings Find first bit set or clear in a string Get the bit value at offset Set or clear the bit at offset Authenticate to the server Get the current connection name Get the current client ID Get info about current connection List all client connections Set client connection attributes Set the connection name Echo the given string Handshake with Redis protocol Ping the server

the following Redis clients after each code change and also periodically: * **[Node-Redis](https://github.com/redis/node-redis)** * **[Jedis](https://github.com/redis/jedis)** * **[Lettuce](https://github.com/lettuce-io/lettuce-core)** * **[Go-Redis](https://github.com/go-redis/redis)** * **[Redis-py](https://github.com/redis/redis-py)**
