-------------------------------------------

             Summary: C* crashes with an OOM error when using the Simba Driver 
on a very wide table
                 Key: CASSANDRA-5336
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5336
             Project: Cassandra
          Issue Type: Bug
          Components: API
    Affects Versions: 1.1.6
         Environment: C* on a Mac with 1GB VM.  Simba ODBC driver
            Reporter: Steven Lowenthal


The Simba driver executes a version of a count(*) query:

SELECT SUM(1) from nhanes3 having sum(1) > 0.   It uses this format so ODBC 
returns a no rows found error if the table is empty.   It translates into a 
series of get_range_slice calls which bring back all of the rows, and for every 
row, it brings back every single column name.   C* crashes with an OOM in the 
thrift code.  The table has almost 600 columns of mixed text and numeric data 
with many empty values.
