Bump reactor-core from 3.4.17 to 3.5.0 in /modules/r2dbc

[dependabot]

Bumps reactor-core from 3.4.17 to 3.5.0.

Release notes

Sourced from reactor-core's releases.

v3.5.0

Reactor-Core 3.5.0 is part of 2022.0.0 Release Train.

This is the first GA release of 2022.0.0 🎉

This note focuses on 3.5.0 proper, curating changes from across all milestones and also includes changes already released as part of 3.4.x line up to 3.4.25.

While there are plenty of improvements and bug fixes, it's worth to highlight the bigger themes first:

• The Mono stack is now more lazy and complies to the Reactive Streams specification by only evaluating the source Publisher after receiving appropriate demand. Previously this usually happened during subscription time.
• We reworked the metrics utilities. Please consult the reference documentation for more details.
• A new context-propagation library has become an important part of the Reactor and Micrometer backbone to allow bridging between reactive and ThreadLocal contextual metadata. Reactor supports this bridging as soon as context-propagation library is present at runtime. Read more in the reference documentation.

Please pay special attention to the following update considerations. More detailed listing of features, bug fixes, and improvements follow.

⚠️ Update considerations and deprecations

⚠️ 🗑️ Removals

• Remove Kotlin extensions by @​simonbasle in #2949
  • These now live in the reactor-kotlin-extensions library
• Remove deprecated Mono.doOn/AfterSuccessOrError by @​simonbasle in #2954
  • The doOn* recommended alternatives include doOnNext(Consumer), doOnError(Consumer), doOnTerminate(Runnable), and doOnSuccess(Consumer),
  • The doAfter* recommended alternatives are doAfterTerminate(Runnable) and doFinally(Consumer).
• Remove deprecated context-related operators by @​simonbasle in #2953
  • deferWithContext(Function) -> use deferContextual(Function) instead,
  • subscriberContext(Context) and subscriberContext(Function) -> use contextWrite(ContextView) and contextWrite(Function) instead,
  • Signal::getContext() -> use Signal::getContextView() instead,
  • Context::putAll(Context) -> use Context::putAll(ContextView) instead.
• Remove deprecated ElasticScheduler by @​simonbasle in #2955
  • Use BoundedElasticScheduler (Schedulers.boundedElastic()) instead.

⚠️ ⌛ Deprecations

• Introduce new module reactor-core-micrometer by @​simonbasle in #3015
  • We introduced a new module, reactor-core-micrometer, and added operators and features supporting the new Observation API of Micrometer 1.10.0, read more about it the release notes.
  • The class reactor.util.Metrics, Flux::metrics() and Mono::metrics() operators have been deprecated.
• Deprecate [Flux|Mono|Synchronous]Sink currentContext by @​simonbasle in #2974, #3021
  • contextView() should be used instead.
• Deprecate scheduler start by @​chemicL in #3236
  • Scheduler#init() method should be used instead. Restart capability is discouraged and the new method is allowed to throw in case of initializing a disposed instance. Please create a new Scheduler instance when necessary.
  • Implementors of Scheduler should also implement the init() method, which currently delegates to start() in the default implementation.

⚠️ ♻️ Behavior Changes

• Make some Mono sources and aggregators lazier by @​OlegDokuka in #3081
• Change behavior of switchOnNext/switchMap default 0 prefetch by @​simonbasle in #2956
• Have concatMap default to 0 prefetch behavior by @​simonbasle in #2967
• take(n) now behaves as take(n,true)/limitRequest by @​simonbasle in #2969
• SourceException wrapper for main stream errors delivered to windows by @​chemicL in #3167
• Scheduler.isDisposed() only true for disposed instances by @​chemicL in #3243
• adds cancellation of the source future support by @​OlegDokuka in #3146
• Scannable.tags() rework, add tagsDeduplicated() by @​simonbasle in #3037
• Disable fusion in MonoSubscriber by @​UgiR in #3245
  • A number of Mono operators derived from the Operators.MonoSubscriber have stopped negotiating fusion (even though their Publisher still implements Fuseable)
  • The highest impact is likely to be on tests that validate the fusion negotiation (eg. StepVerifier's expectFusion(...))
