Upgrade to Cassandra Driver 4.3 [DATACASS-656]

[spring-projects-issues]

Mark Paluch opened DATACASS-656 and commented

We should consider upgrading to Cassandra Driver 4.0. The new driver entirely changes how we integrate with Cassandra as concepts like the Cluster abstraction are no longer present.

Part of this ticket is to investigate whether we are able to migrate to the new driver at all. The OSS driver does not support reactive execution and it comes with a new package structure that requires rebasing of the whole Spring Data Cassandra project onto the new driver structure

Upgrading to the Cassandra 4 driver comes with several breaking changes:

1. New package structure
2. Removal of the intermediate Cluster object
3. Query builder uses immutable objects

Areas of work

1. Major version bump to Spring Data for Apache Cassandra 3
2. Removal of CassandraCqlClusterFactoryBean and CassandraClusterFactoryBean.
3. Extend CassandraCqlSessionFactoryBean with properties from CassandraClusterFactoryBean and CassandraSessionFactoryBean.
4. Deprecate CassandraSessionFactoryBean in favor of CassandraCqlSessionFactoryBean.
5. Keyspace creation and removal will be migrated into CassandraCqlSessionFactoryBean.
6. Migration of connection-related properties to CassandraCqlSessionFactoryBean (was: CassandraClusterFactoryBean)
7. QueryBuilder API must work with immutable query objects

Going forward it would make sense to extract general script handling into ScriptUtils, DatabasePopulator and CqlSessionInitializer utilities.

 

The following unknowns need to be addressed:

• Will reactive support get merged into the OSS driver? If not, then it doesn't make so much sense to have the breaking upgrade as we don't benefit from the driver right now

The code for this ticket resides on the following branch:

https://github.com/spring-projects/spring-data-cassandra/tree/3.0.x

Cassandra driver 4.4 will ship with built-in reactive support so we can remove our bridged reactive session
