> We can use [RocksDB](https://github.com/facebook/rocksdb) to save delayed messages. @cserwen we have done this in https://github.com/didi/DDMQ/tree/master/carrera-chronos. One of the problems in this way is that Rocksdb needs heavy maintenance when instance get large. Compaction will consume quite a mount of IO and interfere with message writing. So we have to make it an external service, and causing more maintenance work. -- This is an automated message from the Apache Git Service.
