My sql table structure is "create table emp (empid int primary key, emp\_first varchar, emp\_last varchar, emp\_dept varchar);"  
and my logstash.conf file  
input {  
jdbc{  
jdbc\_connection\_string =\> "jdbc:cassandra://localhost:9042/dev"  
jdbc\_user =\> "cassandra"  
jdbc\_password =\> "cassandra"  
jdbc\_validate\_connection =\> true  
jdbc\_driver\_library =\> "/Users/nfrteam/.DbSchema/drivers/Cassandra/cassandrajdbc1.1.jar"  
jdbc\_driver\_class =\> "com.dbschema.CassandraJdbcDriver"  
statement =\> "SELECT \* from dev.test\_payload where TIME\_STAMP \> : sql\_last\_value AND BUCKET \> :sql\_last\_value"  
use\_column\_value =\> true  
tracking\_column =\> "TIME\_STAMP"  
tracking\_column\_type =\> "numeric"  
schedule =\> "\* \* \* \* \*"  
tags =\> ["jdbc1"]  
}  
}

output{  
if "jdbc1" in [tags]{  
stdout {  
codec =\> "rubydebug"  
}  
}  
}

I'm getting this error" [logstash.inputs.jdbc] Exception when executing JDBC query {:exception=\>#\<Sequel::DatabaseError: Java::ComDatastaxDriverCoreExceptions::InvalidQueryException: Only EQ and IN relation are supported on the partition key (unless you use the token() function)\>}"

Looks like a Cassandra question to me.
