Subject [Blur Wiki] Update of "DataStructure" by AaronMcCurry
Date Tue, 06 Nov 2012 03:07:08 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Blur Wiki" for change notification.

The "DataStructure" page has been changed by AaronMcCurry:
http://wiki.apache.org/blur/DataStructure?action=diff&rev1=2&rev2=3

  
  While the documents are being added or updated within a single call (Thrift or MapReduce),
they will be guaranteed to exist within the same Lucene segment.  This will be used during
some specialized queries.  See the Lucene IndexWriter for more details.
  
- In the MapReduce framework, the ability to group several Documents together for a single
add or update call will be implemented through the use of common key output in the Mappers.
 The key type will likely need to be defined by the end user based on their needs.  The key
itself won't need to be used.

 The key type will likely need to be defined by the end user based on their needs.  The key
itself won't need to be used for indexing.  If the end user wishes to use the information,
they will need to add the key data to the Document itself.
  
  Analyzers will allow for more customized indexes to be created.  Currently this functionality
is wrapped up in the TableDescriptor, this will need to change.
