Interface RequestTracker

All Superinterfaces:

AutoCloseable

public interface RequestTracker
extends AutoCloseable

Tracks request execution for a session.

There is exactly one tracker per Session. It can be provided either via the configuration (see reference.conf in the manual or core driver JAR), or programmatically via SessionBuilder.withRequestTracker(RequestTracker).
