  == Can I Store BLOBs in Cassandra? ==
  Currently Cassandra isn't optimized specifically for large file or BLOB storage.   However,
files of  around  64Mb and smaller can be easily stored in the database without splitting
them into smaller chunks.  This is primarily due to the fact that Cassandra's public API is
based on Thrift, which offers no streaming abilities;  any value written or fetched has to
fit in to memory.  Other non Thrift  interfaces may solve this problem in the future, but
there are currently no plans to change Thrift's behavior.  When planning  applications that
require storing BLOBS, you should also consider these attributes of Cassandra as well:
   * The main limitation on a column and super column size is that all the data for a single
key and column must fit (on disk) on a single machine(node) in the cluster.  Because keys
alone are used to determine the nodes responsible for replicating their data, the amount of
data associated with a single key has this upper bound. This is an inherent limitation of
the distribution model.

  == Is there a GUI admin tool for Cassandra? ==
  The closest is [[|chiton]], a GTK data browser.
+ Another java UI [[]], a Swing data browser.
