   Hi @segment11,
   
   Thanks for your feedback, Kvrocks currently supports the scan command to iterate keys with prefix. Could you help to add more context if it's NOT exactly what you want?
   
   Reference: https://redis.io/commands/scan/

   I actually want a time series database on rocksdb, and it has replica that can failover.
   Take HBase as example, query n rows scan by rowkey，it is just read some hfiles(sstable) because the rowkeys are ordered.

   Currently, the scan keys in Kvrocks are also ordered indeed, so it should be the same with HBase rows scan.
