Subject Re: Second Cassandra users survey
Date Wed, 02 Nov 2011 04:16:04 GMT
Here is my wish list -

I would love Cassandra to

- provide a efficient method to retrieve the count of columns for a
given row without resorting to read all columns and calculate the
count for a given row key.

- support auto increment column names -  Column slice based query
doesn't  take advantage of  the Column Bloom Filter and it is not
always easy to enumerate the column names in a deterministic manner.

- provide JNA support for Key cache

- remove dependency on running node tool repair when any column is
deleted ( so tombstones doesn't get resurrected )

thanks
Ramesh
