Vivek Mishra commented on CASSANDRA-2124:
-----------------------------------------
Hi Eric,
Looked into python decoder as a newbie to python.
But it looks to me as :
1) Decode column value using column family validator and comparator.
Same is with java decoder
Logic is :
1) On invocation of CassandraStatement execution, make static call to
ColumnDecoder with query and keyspace.
2) Implicitly retrieve column family using pattern matching.
3) CassandraResultSet.next() method is changed to pick columnValue from
ColumnDecoder.getColumnValue(col.getValue()).
This automatically decodes(cast) object into required format.
I can see that it looks to me both (py and java) more or less on same path.
Having something like describe_column_family later can be a big thing.

> replacement for) would also be interesting.
