  == What To Cache ==
  
- The TableDescriptor in the Thrift API contains 2 properties, `blockCaching` (boolean) and
`blockCachingFileTypes` (Set<String>).  You may disable block caching for a given table
by setting blockCaching = false, by deafult it's set to true.  To control the blockCachingFileTypes
create a set with the given Lucene file type extensions that you wish to cache.  If you leave
this null the default is to cache ALL Lucene file types except for the FDT and FDX file types
which are used for data retrieval only and are not accessed during the search itself.  This
has proven to provide excellent search performance while balancing memory constraints.
