Are there tools to simulate failures to trigger the Java driver retry policies?

Using Java Datastax Driver 3.x

We are planning to implement a customer retry policy and provide it when the Cluster is being configured i.e. #withRetryPolicy. Are there any tools / libs that we can use to test this by simulating the Cassandra failures?

The quick answer is no, there aren't.

Read and write timeouts are generally a result of the cluster being overloaded and replicas not able to respond to the coordinator within the timeout window. The only way to simulate your cluster being overloaded is by overloading it. :)

Or with onRequestAborted, it is triggered by network interruptions or outages so you can only trigger by simulating infrastructure outages. Cheers!
