The number we get is in 'partition info ', it's copy of leader replica. And the numbers of followers are in 'partition_meta', we don't count them

TODO: clarify it in doc

  • for memory table: its table data + index
  • rows count may not accurate from different indexes
  • multiple by replica_num for actual mem size, regardless it happens or not
