What are the alternative Java driver 3.6.0 APIs for migrating to 4.x?

Hi Team, We are migrating the project from IBMJDK1.8 to OpenJDK11 with Karaf 4.2.10 and Datastax from 3.6.0 to 4.0.0 or above.

my question is :

what are the alternatives for the below mentioned APIs which are from 3.6.0 to 4.0.0 or to 4.2.1(com.datastax.oss.driver). We are struggling to find the the alternatives for below mentioned APIs:

import com.datastax.driver.core.Session;
import com.datastax.driver.core.UserType;
import com.datastax.driver.core.Cluster;
import com.datastax.driver.core.HostDistance;
import com.datastax.driver.core.JdkSSLOptions;
import com.datastax.driver.core.KeyspaceMetadata;
import com.datastax.driver.core.PoolingOptions;
import com.datastax.driver.core.ProtocolVersion;
import com.datastax.driver.core.SSLOptions;
import com.datastax.driver.core.Session;
import com.datastax.driver.core.UserType;
import com.datastax.driver.core.policies.DCAwareRoundRobinPolicy;
import com.datastax.driver.core.RegularStatement;
import com.datastax.driver.core.querybuilder.QueryBuilder;

Could you please help on this?

The Java driver was redesigned in version 4 so it is not binary-compatible with older versions. You will need to rewrite your application to use the new APIs.

For example, Cluster does not exist anymore and was replaced with CqlSession. See the Java driver Upgrade Guide for details.

In addition, we advise against upgrading to old versions of the driver. Instead, we recommend you upgrade to the latest version which at the time of writing is Java driver v4.9. Cheers!
