How do I use a Transaction in a Reactive Flow in Spring Integration?

Asked 2021-Jun-15 at 18:32

I am querying a database for an item using R2DBC and Spring Integration. I want to extend the transaction boundary a bit to include a handler - if the handler fails I want to roll back the database operation. But I'm having difficulty even establishing transactionality explicitly in my integration flow. The flow is defined as

Well, it's indeed not possible that declarative way since we don't have hook for injecting to the reactive type in the middle on that level.

QUESTION

Java RX's Flux.merge and switchIfEmpty

Asked 2021-Jun-15 at 08:37

I am trying to understand how JavaRx's Flux.merge and switchIfEmpty work together in regards to the below code as I am a bit confused on results I am seeing which is no doubt the result of my not fully grasping Java RX.

My question is ... If the call to wOneRepository... returns an empty list or the call to wTwoRepository... returns an empty list, will the switchIfEmpty code get executed? Or will it only get executed if both calls return an empty list?

...

ANSWER

Answered 2021-Jun-14 at 14:30

switchIfEmpty() will only be called if the upstream Flux completes without emitting anything, and that will only happen if both f1 and f2 complete without emitting anything. So, if both findWidget calls fail, or both return empty Flux instances, or some combination of those, then switchIfEmpty will be called. If either f1 or f2 emits a Widget, then that Widget will be emitted from the merge operator, which means switchIfEmpty will not be called.

Use org.springframework.core.io.buffer.DataBufferUtils to join the DataBuffers from the Flux into a single DataBuffer, and then read that buffer into a byte array.

If you have the option to change the return type of controller's method saveOrUpdateUser to Mono, you can use mono's flatMap method tô return the redirect String like:

I'm beginner in Project Reactor and think it's pretty easy, but I can't find the solution. I have N expensive tasks to do, and I want to implement something like Bounded Semaphore in Java (do not request next element until current count of running task less than K).

MapStruct + Kotlin/JVM(v1.5.10) Error: The return type Flow is an abstract class or interface

Asked 2021-Jun-12 at 07:19

My project uses MapStruct successfully when it does not include Flux or Flow streams. When I try to generate a mapper with a Flow or Flux, I receive an error: "error: The return type Flow is an abstract class or interface." Since Flow and Flux are interfaces, is there a way to still use MapStruct or do I have to roll my own mapper in this use-case?

Thank you for your comments and time

I don't know from what you want to create the Kotlin Flow or Reactor Flux. If it is from other Flow or Flux then you will have to do that partially manual

Evaluate simple RNN in Julia Flux

Asked 2021-Jun-11 at 12:27

I'm trying to learn Recurrent Neural Networks (RNN) with Flux.jl in Julia by following along some tutorials, like Char RNN from the FluxML/model-zoo.

I managed to build and train a model containing some RNN cells, but am failing to evaluate the model after training.

Can someone point out what I'm missing for this code to evaluate a simple (untrained) RNN?

Reactor's Flux Fan out and Zip it?

Asked 2021-Jun-09 at 13:30

I am trying to do following operations on Flux/Publisher which can only be read once ( think database results which can be read once). But, this question is generic enough that it can be answered in functional programming context without reactor knowledge.

count unique item
check if an element exists
Don't call the publisher/flux generator multiple times.

ANSWER

Answered 2021-Jun-09 at 11:57

What you're attempting to do is a reduction of your dataset. It means that you attempt to create a single result by merging your initial elements.

Note that count can be considered as a kind of reduction, and in your case, you want an advanced kind of count operation, that also check if at least one of the input elements is equal to a given value.

With reactor (and many other stream framework), you can use the reduce operator.

Let's try your first example with it :

Throw an exception if a Reactor Flux doesn't complete in a set time

I have a potentially long-running Flux that I'd like to stop after a certain duration has passed. I've found several methods of doing this, however what I'm struggling with is how to be able to tell that the Flux timed out rather than just completed naturally.

Sample (very simple) code:

ANSWER

Answered 2021-Jun-05 at 21:35

Instead of using take(), you can use .mergeWith(Flux.never().timeout(Duration.ofMillis(500))) to merge your flux with another that will always throw a timeout exception after a certain timeframe.

To take your example, you'd do something like:
