             Summary: Add a new read mode to perform bounded staleness snapshot 
reads
                 Key: KUDU-1704
                 URL: https://issues.apache.org/jira/browse/KUDU-1704
             Project: Kudu
          Issue Type: Improvement
    Affects Versions: 1.1.0
            Reporter: David Alves
            Assignee: David Alves


It would be useful to be able to perform snapshot reads at a timestamp that is 
higher than a client provided timestamp, thus improving recency, but lower that 
the server's oldest inflight transaction, thus minimizing the scan's chance to 
block.

Such a mode would not guarantee linearizability, but would still allow for 
client-local read-your-writes, which seems to be one of the properties users 
care about the most.

This should likely be the new default read mode for scanners.
