{quote}Tables with compact storage can only have a single column, so you 
shouldn’t be able to create a compact storage table with 2 columns.
{quote}
According to [http://cassandra.apache.org/doc/latest/cql/ddl.html] that 
restriction is only for tables with clustering columns:
{quote}if a compact table has at least one clustering column, then it must have 
exactly one column outside of the primary key ones.
{quote}
We have a lot of tables created from thrift (compact storage) that do not have 
clustering columns and have > 1 column in the CQL schema.

> Hello
> During an upgrade from 2.1.17 to 3.11.4, our application starting getting 
> back incomplete results for range queries. When all nodes were upgraded 
> (before upgrading sstables), we stopped getting incomplete results. I was 
> able to reproduce it and listed steps below. It seems to require the random 
> partitioner and compact storage to reproduce reliably. It also reproduces 
> coming from 2.1.21 and 2.2.14. You seem to get the bad behavior when an old 
> node is your coordinator and it has to talk to an upgraded replica.

[jira] [Commented] (CASSANDRA-2500) Ruby dbi client (for CQL) that conforms to AR:ConnectionAdapter

Currently all of the tests run against mock objects (no round trip tests 
against C*). It seems like the tests that Jonathan mentioned would benefit from 
actually hitting a C* instance. Any thoughts on this?

 Key: CASSANDRA-2500
 URL: https://issues.apache.org/jira/browse/CASSANDRA-2500
 Project: Cassandra
  Issue Type: Task
  Components: API
Reporter: Jon Hermes
Assignee: Kelley Reynolds
  Labels: cql
 Fix For: 0.8.6

 Attachments: 2500.txt, genthriftrb.txt, rbcql-0.0.0.tgz


 Create a ruby driver for CQL.
 Lacking something standard (such as py-dbapi), going with something common 
 instead -- RoR ActiveRecord Connection Adapter 
 (http://api.rubyonrails.org/classes/ActiveRecord/ConnectionAdapters/AbstractAdapter.html).
