Subject [jira] [Created] (ACCUMULO-2008) Block cache reserves section for in-memory blocks
Date Thu, 12 Dec 2013 19:32:08 GMT
Billie Rinaldi created ACCUMULO-2008:

             Summary: Block cache reserves section for in-memory blocks
                 Key: ACCUMULO-2008
             Project: Accumulo
          Issue Type: Bug
          Components: tserver
    Affects Versions: 1.5.0, 1.4.4, 1.6.0
            Reporter: Billie Rinaldi
             Fix For: 1.7.0

The block cache reserves a quarter of its size for in-memory blocks, but Accumulo doesn't
have any in-memory blocks.  This makes the cache size parameters misleading, because the cache
will effectively end up using 75% of its specified size.  This could be fixed by changing
the default percentages in LruBlockCache, or by using the constructor takes the percentages
as parameters.
