Description

We have this unique requirement where some column families hold data that is indexed from other existing column families. The index data is very large, and we end up writing these inserts into the WAL and then into the store files. In addition to taking more iops, this also slows down splitting files for recovery, etc.

Creating this task to have an option to suppress WAL logging on a per CF basis.
