v0.60 : anyOf and EagerFutureStream operations on underlying Futures

New in SimpleReact v0.60

anyOf enhancement

anyOf progresses the flow with the first result received.

Example

 new SimpleReact().reactToCollection(urls)
                            .map(restAgent::call)
                            .anyOf(processor::transform)
                            .then(saver::save);

EagerFutureStream operations on underlying Futures

EagerFutureSteam operations typically operate on the result of an operation rather than the underlying Stream of CompletableFutures. For example limit works by accepting the first X results and rejecting all subsequent ones.

limitFutures on the other hand operates on the underlying Futures in much the same way as LazyFutureStream limit does. (LazyFutureStream typically operates on the underlying Futures as they can be infinite in size). e.g.

[Behaviour for LazyFutureStream limit and EagerFutureStream limitFutures]

The new Future operations are

limitFutures

skipFutures

zipFutures

zipFuturesWithIndex

duplicateFutures

splitAtFutures

sliceFutures

compared with standard slice

Bug fix for EagerFutureStream.slice

v0.5 : Hierarchical failure handling

New in SimpleReact v0.5

Error Handling (onFail) enhancements.

onFail calls can be chained to handle different exceptions for a stage.

Example

    new EagerReact().react(()->1,()->2)
        .then(this::makeRestRequests)
        .onFail(TimeoutException.class, e-> markHostUnreachable(e.getValue()) )
        .onFail(InvalidResponseException.class, e->  markHostCommunicationIssue(e.getValue())
        .onFail(Throwable.class, e-> handleUnexpectedException(e))
        .collect(Collectors.toList());

v0.41 : EagerReact and LazyReact API bug fix

Both EagerReact and LazyReact we're returning a sub-class type SimpleReactStream rather than EagerFutureStream or LazyFutureStream on the

EagerReact#react(Supplier... s) method.

This release fixes this issue.

v0.4

New in SimpleReact v0.4

API Simplification into 3 separate Streaming APIs

Implementing java.util.stream.Stream & org.jooq.lambda.Seq :

• EagerFutureStream : An easy to use JDK 8 Stream of CompletableFutures, with all of the SimpleReact API methods, and scala-like jOOλ Seq methods too. EagerFutureStream kicks of future tasks eagerly and can be run in either parallel or sequential (free-threaded) modes.
• LazyFutureStream : Provides a Lazy JDK 8 Stream of CompletableFutures (and Seq, and SimpleReact API methods). Can be used for constant proccessing (e.g. of data coming in off a SimpleReact asynchronous queue).

Smaller / focused Api

• SimpleReactStream : Provides a simple, focused API for Streaming Futures based on the Promises / A++ spec.

Other changes

onFail method can now capture input to the previous stage that failed.

Simple React v0.3

New in SimpleReact v0.3

SimpleReact Stage implements java.util.stream.Stream. This adds methods such as flatMap, reduce, max, min to SimpleReact.

SimpleReact Stage implements org.jooq.lambda.Seq - which extends Stream. This adds methods such as zip, concat, foldLeft, foldRight, unzip to SimpleReact.

SimpleReact introduces automatic configurable aysnchronous retry support.

Better support for Infinite Streaming.

More performant results capturing for lazy streams.

Better performance due to configurable capacity monitoring.

Static Factory methods moved to ReactStream class.
