…t is cancelled. There was a critical issue when the external code cancels a request, indeed the cached CompletableFuture will then always throw a CancellationException. This may happens, for example, when used by reactive like Mono.zip or Mono.firstWithValue.

I agree this is ultimately the right approach but I think I'd rather do more to completely decouple the futures returned to the user from the future that computes the PreparedStatement object. #2003 as an example. |

#2003 didn't work nearly as well as I'd hoped. Closing that out and going with this for now; we can always refactor things later if we feel we need to make the interacting components clearer. Thanks for the patch @lucboutier! |

It however doesn't check for cases where nothing has been bound yet on the statement. This causes more problems if the user decides to get a BoundStatementBuilder from the PreparedStatement, set some fields on it, and then copy it by constructing new BoundStatementBuilder objects with the BoundStatement as a parameter, since the empty ByteBuffer gets copied to all bound statements, resulting in all requests being targeted to the same Cassandra node in a token-aware load balancing policy. patch by Ammar Khaku; reviewed by Andy Tolbert, and Bret McGuire reference: apache#1620 * JAVA-3167: CompletableFutures.allSuccessful() may return never completed future patch by Lukasz Antoniak; reviewed by Andy Tolbert, and Bret McGuire for JAVA-3167 * ninja-fix Various test fixes * Run integration tests with DSE 6.9.0 patch by Lukasz Antoniak; reviewed by Bret McGuire reference: apache#1955 * JAVA-3117: Call CcmCustomRule#after if CcmCustomRule#before fails to allow subsequent tests to run patch by Henry Hughes; reviewed by Alexandre Dutra and Andy Tolbert for JAVA-3117 * JAVA-3149: Support request cancellation in request throttler patch by Lukasz Antoniak; reviewed by Andy Tolbert and Chris Lohfink for JAVA-3149 * Fix C* 3.0 tests failing on Jenkins patch by Lukasz Antoniak; reviewed by Bret McGuire reference: apache#1939 * Reduce lock held duration in ConcurrencyLimitingRequestThrottler It might take some (small) time for callback handling when the throttler request proceeds to submission. Before this change, the throttler proceed request will happen while holding the lock, preventing other tasks from proceeding when there is spare capacity and even preventing tasks from enqueuing until the callback completes. By tracking the expected outcome, we can perform the callback outside of the lock. This means that request registration and submission can proceed even when a long callback is being processed. patch by Jason Koch; Reviewed by Andy Tolbert and Chris Lohfink for CASSANDRA-19922 * Annotate BatchStatement, Statement, SimpleStatement methods with CheckReturnValue Since the driver's default implementation is for BatchStatement and SimpleStatement methods to be immutable, we should annotate those methods with @CheckReturnValue.

There was a critical issue in the driver that may occur when the external code cancels a request, indeed the CompletableFuture will then always throw a CancellationException.
This could occur for example when used in a reactive context with a Mono.zip failed.
