New page:
== Data Structure Development ==

Any data structure development in Blur needs to have a manageable memory footprint.  The easiest
way achieve this behavior is to make the data structure file based (through the Lucene Directory
API).  Implementing a file based data structure will make use the BlockCacheDirectory which
will automatically cache block of the files in use.

If a data structure cannot be written to use the file API then a manageable memory model will
have to be implemented.

The reasoning for this is development strategy is three fold:

JVM Heap limitations
Data grow issues
User query requirements
