------------------------------------

             Summary: MultiTableBatchScanner
                 Key: ACCUMULO-1737
                 URL: https://issues.apache.org/jira/browse/ACCUMULO-1737
             Project: Accumulo
          Issue Type: Improvement
          Components: client
            Reporter: John Vines


We currently have the BatchScanner, which does not guarantee in order results with the benefit
of higher parallellization. Unfortunately, if you want to query multiple tables, the only
option is to chain BatchScanner's together, but you lose something of the optimizations under
the hood for both using system resources well as well as getting data back in order. We have
another ticket for multi-table accumulo input format for mapreduce, but I would like to see
a multi table version of a batch scanner for regular client use.
