For it both of them are `HostDistance.REMOTE` (will be after https://github.com/scylladb/java-driver/issues/369 is fixed). We need to have another `HostDistance` to make it work.

When session manager prepares query on other hosts it borrows connection with 0 `timeout` and `maxQueueSize`: https://github.com/scylladb/java-driver/blob/cd0b08e8bba2758edd957ee5c62cd7988327c12b/driver-core/src/main/java/com/datastax/driver/core/SessionManager.java#L747-L757 Both these parameters can endup at `HostConnectionPool.enqueue` under certain conditions, which will make...

3.x: PoolingOptions.maxQueueSize is too small

Currently it is 256, which means that driver allows only 256 pending requests. Given the fact that there are nodes in the wild with 128 shards it is too low....

4.x: investigate and fix why DefaultLoadBalancingPolicyIT.should_apply_node_filter is failing

It randomly fails: ``` Error: Tests run: 5, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 15.755 s

Scylla supports `USING TTL` we need to remove safeguard and make it work.

Both `CassandraRequirement` and `DseRequirement` are going to be depricated and to be removed on next minor update. We need to do the same for `ScyllaRequirement`.

It fails to start scylla cluster. Let's investigate and fix it.

It fails with: ``` com.datastax.oss.driver.api.core.servererrors.ProtocolError: truncated frame: expected 65540 bytes, length is 72 at com.datastax.oss.driver.api.core.servererrors.ProtocolError.copy(ProtocolError.java:54) at com.datastax.oss.driver.internal.core.util.concurrent.CompletableFutures.getUninterruptibly(CompletableFutures.java:154) at com.datastax.oss.driver.internal.core.cql.CqlPrepareSyncProcessor.process(CqlPrepareSyncProcessor.java:61) at com.datastax.oss.driver.internal.core.cql.CqlPrepareSyncProcessor.process(CqlPrepareSyncProcessor.java:33) at com.datastax.oss.driver.internal.core.session.DefaultSession.execute(DefaultSession.java:241) at com.datastax.oss.driver.api.core.cql.SyncCqlSession.prepare(SyncCqlSession.java:208) at com.datastax.oss.driver.core.cql.BoundStatementCcmIT.should_propagate_attributes_when_preparing_a_simple_statement(BoundStatementCcmIT.java:351) ```

There are problems with `DescribeIT` suite, all of them we can solve and enable it.
