InputMetricsUpdater

sealed trait InputMetricsUpdater extends MetricsUpdater

A trait that provides a method to update read metrics which are collected for connector related tasks. The appropriate instance is created by the companion object.

Instances of this trait are not thread-safe. They do not need to because a single instance should be created for each Cassandra read task. This remains valid as long as Cassandra read tasks are single-threaded.
