John Blum opened DATACASS-320 and commented

Update CassandraCqlClusterFactoryBean to include a setSpeculativeExecutionPolicy(:SpeculativeExecutionPolicy) method and update the afterPropertiesSet() method to set on the Cluster.Builder.

Example SpeculativeExecutionPolicy usage:

PerHostPercentileTracker tracker = PerHostPercentileTracker
    .builderWithHighestTrackableLatencyMillis(15000)
    .build();

PercentileSpeculativeExecutionPolicy policy = new PercentileSpeculativeExecutionPolicy(tracker, 99.0, 2);

Cluster.builder().addContactPoint("127.0.0.1")
    .withSpeculativeExecutionPolicy(policy)
    .build();

Affects: 1.4.2 (Hopper SR2)
