示例1: RequestHandlerRetryDecisionTest
public void RequestHandlerRetryDecisionTest()
{
var statement = new SimpleStatement("SELECT WILL FAIL");
var request = Session.GetRequest(statement);
var requestHandler = new RequestHandler<RowSet>(Session, request, statement);
//Using default retry policy the decision will always be to rethrow on read/write timeout
var expected = RetryDecision.RetryDecisionType.Rethrow;
var decision = requestHandler.GetRetryDecision(new ReadTimeoutException(ConsistencyLevel.Quorum, 1, 2, true));
Assert.AreEqual(expected, decision.DecisionType);
decision = requestHandler.GetRetryDecision(new WriteTimeoutException(ConsistencyLevel.Quorum, 1, 2, "SIMPLE"));
Assert.AreEqual(expected, decision.DecisionType);
decision = requestHandler.GetRetryDecision(new UnavailableException(ConsistencyLevel.Quorum, 2, 1));
Assert.AreEqual(expected, decision.DecisionType);
decision = requestHandler.GetRetryDecision(new Exception());
Assert.AreEqual(expected, decision.DecisionType);
//Expecting to retry when a Cassandra node is Bootstrapping/overloaded
expected = RetryDecision.RetryDecisionType.Retry;
decision = requestHandler.GetRetryDecision(new OverloadedException(null));

public void DowngradingConsistencyRetryTest()
{
var dummyStatement = new SimpleStatement().SetRetryPolicy(DowngradingConsistencyRetryPolicy.Instance);
var handler = new RequestHandler<RowSet>(null, null, dummyStatement);
//Retry if 1 of 2 replicas are alive
var decision = handler.GetRetryDecision(new UnavailableException(ConsistencyLevel.Two, 2, 1));
Assert.True(decision != null && decision.DecisionType == RetryDecision.RetryDecisionType.Retry);
//Retry if 2 of 3 replicas are alive
decision = handler.GetRetryDecision(new UnavailableException(ConsistencyLevel.Three, 3, 2));
