Subject [Hadoop Wiki] Update of "Hbase/SecondaryIndexing" by jgray
Date Mon, 28 Feb 2011 20:03:08 GMT
Dear Wiki user,

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

The "Hbase/SecondaryIndexing" page has been changed by jgray.
http://wiki.apache.org/hadoop/Hbase/SecondaryIndexing?action=diff&rev1=3&rev2=4

--------------------------------------------------

  Other open questions:
  
  * Creation of secondary tables (auto-bootstrapped?  part of coprocessor init?  manual?)
- 
+ * Read API
  
  Future work:
  
  * Declaration of indexes via API or shell syntax rather than programatically with a coprocessor-per-index
  * Creation of indexes on existing tables (build of indexes based on current data and kept
up to date)
  * Option to apply secondary update in a synchronous fashion (if you want to take performance
hit and have stronger consistency of the index)
- 
+ * Storing of primary table data in secondary table to provide single-lookup denormalized
join
