A timestamp generator that never sends a timestamp with any query, therefore letting Cassandra
assign a server-side timestamp.
To activate this generator, modify the advanced.timestamp-generator
section in the driver configuration, for example:
datastax-java-driver {
advanced.timestamp-generator {
class = ServerSideTimestampGenerator
}
}
See reference.conf
(in the manual or core driver JAR) for more details. /**
