Subject Re: Any improvements in Cassandra JDBC driver ?
Date Thu, 29 Mar 2012 17:19:30 GMT
What I want to tell was this driver does not use INSERT key word.  Since
CQL support for using INSERT keyword and it is more generic key word used
to add new records, it's more user friendly to  use INSERT key word  to add
new record set rather using UPDATE keyword.
