Subject Composite Column Types Storage
Date Wed, 12 Sep 2012 11:39:27 GMT
We have a requirement, where storage format will need to use a composite
column, that has 2 parts. A string and an integer

Ex:

<Some-String> [column-name]
                     <id1>,<id2>,<id3>..... [composite column]

I did not choose super-column because the number of sub-columns could
quickly get bigger. However, i am not able to find info on how composite
columns are persisted to disk

Is every <string>/<id> combination stored separately in disk or is there
some form of composite-column-name sharing implemented to reduce disk space.

Regards,
Ravi
