            How to use RXJS to share a pool of resources between multiple consumers
            Asked 2022-Mar-31 at 12:55

            How can we divide work of consumers over a limited set of resources in RXJS?

            I have a Pool class here (simplified):

            So the main thing is you need to share the actual part that does the work, not only the resources.

            How to implement the logic without state variables
            Asked 2022-Mar-23 at 18:10

            There are two observables: the first named activator emits booleans. The second named signaler emits void events. There's a function f() which must be called under the next conditions:

            If the last event from activator is true, and event from signaler comes, call f(). Otherwise (the last activator's event is false, or activator has not yet emitted anything), "remember" that signaler sent the event. As soon as activator emits true, call f() and clear "remembered" flag.




            Answered 2022-Mar-23 at 18:10

            You need a state machine, but you can contain the state so you aren't leaving the monad... Something like this:



            Caching parallel request in Spring Webflux Mono
            Asked 2022-Mar-10 at 21:09

            We are using spring webflux (project reactor), as part of the requirement we need to call one API from our server.

            For the API call, we need to cache the response. So we are using Mono.cache operator.

            It caches the response Mono and the next time the same API call happens, it will get it from the cache. Following is example implementation



            Answered 2022-Mar-03 at 14:54

            You can initialize the Mono in the constructor (assuming it doesn't depend on any request time parameter). Using cache operator will prevent multiple subscriptions to the source.



            Mirror at most 1 value from source, then temporarily drop values until another observable emits
            Asked 2022-Jan-20 at 13:05

            I would like to combine two observables in such a way that

            • I mirror at most 1 value from the source observable (same moment it arrives),
            • Then ignore its subsequent values until the notifier observable emits;
            • Then, I allow to mirror at most 1 more value from the source;
            • After which I again ignore elements until the notifier observable emits
            • etc.

            I believe this is a simple use case of the throttle() operator.

            UseCases or Interactors with Kt Flow and Retrofit
            Asked 2021-Dec-06 at 15:34


            I started working on a new project and I've decided to move from RxJava to Kotlin Coroutines. I'm using an MVVM clean architecture, meaning that my ViewModels communicate to UseCases classes, and these UseCases classes use one or many Repositories to fetch data from network.

            Let me give you an example. Let's say we have a screen that is supposed to show the user profile information. So we have the UserProfileViewModel:



            Answered 2021-Dec-06 at 14:53

            The most obvious problem I see here is that you're using Flow for single values instead of suspend functions.

            Coroutines makes the single-value use case much simpler by using suspend functions that return plain values or throw exceptions. You can of course also make them return Result-like classes to encapsulate errors instead of actually using exceptions, but the important part is that with suspend functions you are exposing a seemingly synchronous (thus convenient) API while still benefitting from asynchronous runtime.

            In the provided examples you're not subscribing for updates anywhere, all flows actually just give a single element and complete, so there is no real reason to use flows and it complicates the code. It also makes it harder to read for people used to coroutines because it looks like multiple values are coming, and potentially collect being infinite, but it's not the case.

            Each time you write flow { emit(x) } it should just be x.

            Following the above, you're sometimes using flatMapMerge and in the lambda you create flows with a single element. Unless you're looking for parallelization of the computation, you should simply go for .map { ... } instead. So replace this:



            DT: Dynamically change column values based on selectinput from another column in R shiny app
            Asked 2021-Nov-15 at 09:56

            I am trying to create a table (with DT, pls don't use rhandsontable) which has few existing columns, one selectinput column (where each row will have options to choose) and finally another column which will be populated based on what user select from selectinput dropdown for each row.

            in my example here, 'Feedback' column is the user dropdown selection column. I am not able to update the 'Score' column which will be based on the selection from 'Feedback' column dropdown.



            Answered 2021-Sep-30 at 14:31

            I'd suggest using dataTableProxy along with replaceData to realize the desired behaviour. This is faster than re-rendering the datatable.

            Furthermore, re-rendering the table seems to be messing around with the bindings of the selectInputs.

            Also please note: for this to work I needed to switch to server = TRUE

            Changing the target of a `whenever` block from the inside
            Asked 2021-Oct-07 at 10:20

            The following code attempts to react to one Supply and then, based on the content of some message, change its mind and react to messages from a different Supply. It's an attempt to provide similar behavior to Supply.migrate but with a bit more control.



            Answered 2021-Oct-07 at 10:20

            I tend to consider whenever as the reactive equivalent of for. (It even supports the LAST loop phaser for doing something when the tapped Supply is done, as well as supporting next, last, and redo like an ordinary for loop!) Consider this:

            The issue appears to be a Combine bug, as pointed out here. Using Publishers.Sequence causes the following operator to accumulate every value sent downstream before proceeding.

            A workaround is to type-erase the sequence publisher:
