Do I need to lock before setting some bucket in redisson?

Question

If I want to set a bucket in Redisson, do I need to prevent race condition by incorporating Redisson.getLock()? Or RBucket.set() does that internally?

In general, other than application requirements, is there any scenario that I need to surround a block by locks before setting / getting something to / from Redisson?

Actually you don't need to use Lock with Bucket object, because all redis/redisson operations are atomic.

Could you please provide some reference too? – Mehran Dec 20 '16 at 18:20
@Mehran https://redis.io/commands/eval `Atomicity of scripts` section. Redisson uses lot of lua scripts. Redis is single-threaded process. Thus, only one command could be executed concurrently. – Nikita Koksharov Dec 20 '16 at 20:07
