Subject Re: Is SuperColumn necessary?
Date Wed, 28 Apr 2010 10:44:08 GMT
I don't think secondary index is necessary for cassandra core, at least it
is not urgent.
I think currently, the first urgent improvements of cassandra are:
1. re-clarify the data-model.
2. re-implement the storage and index, especially the current SSTable
implement is not good.

In fact, the current storage/index implement is the most poor point.
