compound primary key not supported #55

Open kylehr opened 11 years ago

kylehr commented 11 years ago

Hi guys,

The traceback at the end of this post shows the datastax example failing to load. This works from cqlsh ...

cqlsh:k1> CREATE TABLE timeline ( user_id varchar, tweet_id uuid, author varchar, body varchar, PRIMARY KEY (user_id, tweet_id)) ; cqlsh:k1>

I was expecting the string to be passed straight through so apologies if I am missing something.

Cheers, Kyle

Hi there,

You are most likely connecting to Cassandra using CQL2, and compound keys are a CQL3 feature. Pass the correct cql_version in the client options and it should work fine.

db = CassandraCQL::Database.new('127.0.0.1:9160', {:cql_version => "3.0.0"'})

Same error here. After adding cql_version error changes to

cassandra-cql 1.2.1 thrift 0.8.0 thrift-client 0.8.4

What cassandra version are you using?

vitaliy commented 11 years ago

1.2.6

from what I see it's an issue with thrift client. in cassandra-cql:

def use_cql3? (@cql_version.nil? || @cql_version.split('.').first.to_i >= 3) && CassandraCQL::Thrift::Client.method_defined?(:execute_cql3_query) end

for me CassandraCQL::Thrift::Client.method_defined?(:execute_cql3_query) is false.
