Kreds is a thread-safe, idiomatic, coroutine based Redis client written in 100% Kotlin.
## Why Kreds?
* Kreds is designed to be EASY to use.
* Kreds has clean API, clear return types, **avoid the dreaded null pointer exception at compile time!**
* Kreds is built around coroutines, providing you an **imperative paradigm of programming without blocking threads, futures or callback hell**, thanks to Kotlin Coroutines!
* Run blocking commands **without blocking** Java threads. (Only the inexpensive coroutines are blocked)
* Kreds uses Netty under the hood and is **truly asynchronous**.
* High throughput.
## Use cases
* Web app cache client: Don't open multiple connections to redis, for each http request, use single connection in a thread-safe manner.
* Pub/Sub: Subscribe to multiple channels from one or multiple Redis, without being limited by java threads.
## Compatibility
* Java 11 and above
* Compatible with Redis: 6 and above.
* Tested against Redis: 6.2.7, 7.0
## Documentation

newClient(Endpoint.from("127.0.0.1:6379")).use { client ->
client.set("foo","100")
println("incremented value of foo ${client.incr("foo")}") // prints 101
client.expire("foo",3u) // set expiration to 3 seconds
delay(3000)
assert(client.get("foo") == null)
}
}
```
