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

             Summary: Add an option to skip adding bytes to block-cache in CacheIndexInput
                 Key: BLUR-481
                 URL: https://issues.apache.org/jira/browse/BLUR-481
             Project: Apache Blur
          Issue Type: Improvement
          Components: Blur
    Affects Versions: 0.2.4
            Reporter: Ravikumar
            Priority: Minor


We are working on a specific use-case where we attempt to utilize OS buffer-cache instead
of block-cache for local reads. We have extended CacheIndexInput but found that data is duplicated
in both OS as well block-cache. Wanted to by-pass block-cache & hence the patch


Ultimately we should also expose controls to partially add chosen blocks of a file into block-cache
