com.hazelcast.spi.impl.sequence.FailFastCallIdSequence

All Implemented Interfaces:

CallIdSequence

public class FailFastCallIdSequence
extends AbstractCallIdSequence

A CallIdSequence that provides backpressure by taking the number of in-flight operations into account when before creating a new call-id.

It is possible to temporarily create more concurrent invocations than the declared capacity due to:

• system operations
• the racy nature of checking if space is available and getting the next sequence.

The latter cause is not a problem since the capacity is exceeded temporarily and it isn't sustainable. So perhaps there are a few threads that at the same time see that the there is space and do a next.
