[Cassandra-user] Working with legacy data via CQL
Nov 12, 2014 at 8:09 am
: What version of cassandra did you originally create the column family in? Have you made any schema changes to it through cql or cassandra-cli, or has it always been exactly the same? -- Tyler Hobbs DataStax
: Oh that's a tough question given that the cluster has been around since 2011. So CF was probably created in Cassandra 0.7 or 0.8 via thrift calls from pycassa, and I don't think there has been any schema changes to it since. Thanks, \EF
: Actually, I don't think it matters. I created a minimal repeatable set of python code (see below). Running that against a 2.0.11 server, creating fresh keyspace and CF, then insert some data with thrift/pycassa, then trying to extract the data that has a different validation class, the python-driver and cqlsh bails out. cqlsh example after running the below script: cqlsh:badcql> select * from "Users" where column1 = 'default_account_id' ALLOW FILTERING; value
insert data in cassandra from .net..
