> [LOCAL_]SERIAL does not support writes, but the errors can be very confusing
> if you don't know this:
> {noformat}
> cqlsh:foo> INSERT INTO bar (foo ) VALUES ( 'foo' ) ;
> InvalidRequest: code=2200 [Invalid query] message="You must use conditional
> updates for serializable writes"
> cqlsh:foo> INSERT INTO bar (foo ) VALUES ( 'foo' ) if NOT EXISTS ;
> InvalidRequest: code=2200 [Invalid query] message="SERIAL is not supported as
> conditional update commit consistency. Use ANY if you mean "make sure it is
> accepted but I don't care how many replicas commit it for non-SERIAL reads""
> {noformat}
