Peter Lin commented on CASSANDRA-4964:
--------------------------------------

I am using CQL2. If I understand it correctly, CQL3 already handles the case 
where insert/queries use a mix of thrift and CQL.

thanks.

> Currently, org.apache.cassandra.thrift.CqlMetadata doesn't return the column 
> name and value metadata for dynamic columns. If I execute a query against a 
> dynamic column that was inserted through thrift or hector, the name and/or 
> value type may not be the same as the default types declared in the column 
> family definition.
> If the dynamic column was inserted through CQL, it will conform to the 
> defined default types for column name and value. Even in that case, it is 
> still nice to have the metadata returned. That will facilitate developing 
> tools for CQL and make it easier on people writing drivers for Cassandra.
> I'm willing to contribute to this, if someone points me to the right place. 
> I've read a lot of the core cassandra code, but I haven't gone through all of 
> CQL yet.
