In datastax driver we have api like
withTimestampGenerator(new AtomicMonotonicTimestampGenerator())
to enable the feature to setting timestamp per query at client side. How can we achieve same with spring data canssandra.
I am aware that i can use "USING TIMESTAMP value" in cql but is there something which spring data cassandra provide ? I dont find such api in CassandraClusterFactoryBean .
You are correct!
Unfortunately, it appears SD Cassandra is missing a configuration option on the CassandraCqlClusterFactoryBean class supporting the withTimestampGenerator(:TimestampGenerator) configuration setting with the DataStax Java driver Cluster.Builder API.
Equally unfortunate is there is no workaround (other than the USING TIMESTAMP in CQL) at the moment either.
It also appears the CassandraCqlClusterFactoryBean is missing configuration options for:
Though, beware, the withTimestampGenerator(..) is only supported in version 3 of the DataStax Java Driver, which the next version (i.e. 1.5.0) of SD Cassandra will support...
This feature is only available with version V3 or above of the native protocol. With earlier versions, timestamps are always generated server-side, and setting a generator through this method will have no effect.
CassandraCqlClusterFactoryBean) does not support these configuration options, neither will the SD Cassandra XML namespace configuration meta-data (obviously).
The timestamp capability is available in SD 1.5.x,
public void setTimestampGenerator(TimestampGenerator timestampGenerator) {
this.timestampGenerator = timestampGenerator;
}
