Now generating rdb and then full sync is slow for huge data, may cost a long time. So we may think a better way to do this.

Maybe we can use our own file format, only saving the raw backend leveldb/rocksdb data, like below:

generates a snapshot
scans the snapshot from first to last, gets all k-v and saves to a file
transfers this file to slave
slave reads the file and reset
