[jira] [Created] (HBASE-13215) A limit on the raw key values is needed for each next call of a scanner

He Liangliang created HBASE-13215:
-------------------------------------

             Summary: A limit on the raw key values is needed for each next call of a scanner
                 Key: HBASE-13215
                 URL: https://issues.apache.org/jira/browse/HBASE-13215
             Project: HBase
          Issue Type: Improvement
          Components: Scanners
            Reporter: He Liangliang
            Assignee: He Liangliang


In the current scanner next, there are several limits: caching, batch and size. But there is no limit on raw data scanned, so the time consumed by a next call is unbounded. For example, many consecutive deleted or filtered out cells will leads to a socket timeout. This can make user code get stuck.
