Subject Columnar Search Support
Date Tue, 07 Jun 2011 04:21:59 GMT

Does Derby support the Columnar method for querying? If not, is this a
possible thing to implement in Derby, to compare the performance with regard
to row oriented approach? (For some queries only, as an example when
an aggregate
needs to be computed over many rows but only for a smaller subset of all
columns of data)

Thanks and Regards,
