                 Key: DL-159
                 URL: https://issues.apache.org/jira/browse/DL-159
             Project: DistributedLog
          Issue Type: Improvement
          Components: distributedlog-core
            Reporter: Sijie Guo
            Assignee: Sijie Guo
             Fix For: 0.4.0


Current readahead is a batch-read based sequential reads. It doesn't handle 
slow bookies very well. This change is to improve the readahead behavior to use 
a more streaming solution to read ahead.
