Migration Guide from 3.x to 4.x

Spring Data for Apache Cassandra 4.0 introduces a set of breaking changes when upgrading from earlier versions.

Asynchronous Template API

With the deprecation of ListenableFuture, AsyncCqlOperations and AsyncCassandraOperations and their dependant classes were migrated to CompletableFuture. If your application heavily depends on ListenableFuture and you cannot easily migrate to CompletableFuture then we suggest switching to the legacy Async…Operations types in the legacy subpackage. That is org.springframework.data.cassandra.core.cql.legacy for AsyncCqlOperations and org.springframework.data.cassandra.core.legacy for AsyncCassandraOperations.
