Gary Dusbabek commented on CASSANDRA-2124:
------------------------------------------
bq. Should we replace rowmetadata with ResultsetMetaData?
The problem with using ResultSetMetaData is that it is a bad interface for
Cassandra's sparse columns. A good example is that column 0 in one row might
map to a column named "foo", while column 0 in another row might map to a
column named "bar". The Wrappable interface exists so that JDBC driver
implementations can provide features beyond the JDBC API without the ugliness
of casting. I think it is better to make the programmer fully aware that he is
dealing with sparse columns and forcing him to use the RowMetaData API.
I'd like to hear your points on the benefits of using ResultSetMetaData though.
I admit that RowMetaData may not be the ideal way of accessing row-specific
meta information.
