Hi, I have been playing a bit with indexing on top of HBase in a similar manner as Google datastore does with Bigtable.
You can find the results here: http://lilycms.org/lily/index/sketchbook/hbaseindexes.html In short, it is similar to tableindexed in that it uses tables as indexes, but it is focused on the construction of the row keys from various data types (numbers, strings, dates) rather than maintaining the index. It is also possible to merge-join results from multiple indexes. -- Bruno Dumon Outerthought http://outerthought.org/
