When using redis in dump. RDB with temp directory generated + pid. The RDB file, don't know how to, nor colleagues created in the code, I asked him what is generated when he don't know, because can't test restart will be generated, so more troublesome, the younger brother is also use redis soon, don't understand the question is how to return a responsibility, hope to help solve, Daniel

Is useless, but I don't know why have this file, the Internet can't find similar problems, a long time but you know, the programmer is not what they expected in all feel uncomfortable!

what do you mean this is the mechanism of redis itself?

Hello, I have seen this situation, my guess is that: when the trigger RDB redis persistence, if redis data in the memory is too big, can temporarily stored in the temp - pid. RDB file, and then from the temp - pid. RDB file copy to your RDB redis persistence file;
