Steven Lowenthal created CASSANDRA-5336: -------------------------------------------
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. -- This message is automatically generated by JIRA.
