kandi X-RAY | flux Summary

flux is a Go library. flux has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

On Flux v2 In an announcement in August 2019, the expectation was set that the Flux project would integrate the GitOps Engine, then being factored out of ArgoCD. Since the result would be backward-incompatible, it would require a major version bump: Flux v2. After experimentation and considerable thought, we (the maintainers) have found a path to Flux v2 that we think better serves our vision of GitOps: the GitOps Toolkit. In consequence, we do not now plan to integrate GitOps Engine into Flux. :warning: This also means that Flux v1 is in maintenance mode.

            Asked 2022-Mar-25 at 06:14

            I'm trying to initiate a Springboot project using Open Jdk 15, Springboot 2.6.0, Springfox 3. We are working on a project that replaced Netty as the webserver and used Jetty instead because we do not need a non-blocking environment.

            In the code we depend primarily on Reactor API (Flux, Mono), so we can not remove org.springframework.boot:spring-boot-starter-webflux dependencies.

            I replicated the problem that we have in a new project.: https://github.com/jvacaq/spring-fox.

            This problem's caused by a bug in Springfox. It's making an assumption about how Spring MVC is set up that doesn't always hold true. Specifically, it's assuming that MVC's path matching will use the Ant-based path matcher and not the PathPattern-based matcher. PathPattern-based matching has been an option for some time now and is the default as of Spring Boot 2.6.

            As described in Spring Boot 2.6's release notes, you can restore the configuration that Springfox assumes will be used by setting spring.mvc.pathmatch.matching-strategy to ant-path-matcher in your application.properties file. Note that this will only work if you are not using Spring Boot's Actuator. The Actuator always uses PathPattern-based parsing, irrespective of the configured matching-strategy. A change to Springfox will be required if you want to use it with the Actuator in Spring Boot 2.6 and later.

            Manage access to shared resource with Project Reactor
            Asked 2022-Feb-23 at 10:26

            How to manage access to shared resources using Project Reactor?

            Given an imaginary critical component that can execute only operation at the time (file store, expensive remote service, etc), how could one orchestrate in reactive manner access to this component if there are multiple points of access to this component (multiple API methods, subscribers...)? If the resource is free to execute the operation it should execute it right away, if some other operation is already in progress, add my operation to the queue and complete my Mono once my operation is completed.

            My idea is to add tasks to the flux queue which executes tasks one by one and return a Mono which will be complete once the task in the queue is completed, without blocking.

            this looks like a simplified version of what the reactor-pool does, in essence. have you considered using that with eg. a maximum size of 1?

            https://github.com/reactor/reactor-pool/

            https://projectreactor.io/docs/pool/0.2.7/api/reactor/pool/Pool.html

            The pool is probably overkill, because it has the overhead of having to deal with multiple resources on top of multiple competing borrowers like in your case, but maybe it could provide some inspiration for you to go further.

            How to limit concurrent http requests with Mono & Flux
            Asked 2022-Feb-08 at 01:37

            I want to handle Flux to limit concurrent HTTP requests made by List of Mono.

            When some requests are done (received responses), then service requests another until the total count of waiting requests is 15.

            A single request returns a list and triggers another request depending on the result.

            At this point, I want to send requests with limited concurrency. Because consumer side, too many HTTP requests make an opposite server in trouble.

            I am afraid Project Reactor doesn't provide any implementation of either rate or time limit.

            However, you can find a bunch of 3rd party libraries that provide such functionality and are compatible with Project Reactor. As far as I know, resilience4-reactor supports that and is also compatible with Spring and Spring Boot frameworks.

            The RateLimiterOperator checks if a downstream subscriber/observer can acquire a permission to subscribe to an upstream Publisher. If the rate limit would be exceeded, the RateLimiterOperator could either delay requesting data from the upstream or it can emit a RequestNotPermitted error to the downstream subscriber.

            Based on the paper you shared, it looks like you need to change the weight arrays per each output neuron per each layer. Unfortunately, this means that the implementation of your optimization routine is going to depend on the layer type, since an "output neuron" for a convolution layer is quite different than a fully-connected layer. In other words, just looping over Flux.params(model) is not going to be sufficient, since this is just a set of all the weight arrays in the model and each weight array is treated differently depending on which layer it comes from.

            Fortunately, Julia's multiple dispatch does make this easier to write if you use separate functions instead of a giant loop. I'll summarize the algorithm using the pseudo-code below:

            I'm not terribly familiar with your stack, so this is a high-level answer to hit on your "Why". There WILL be a more specific answer for you, somewhere down the pipe (e.g. someone that can confirm whether this thread is relevant).

            While I'm no Spring Daisy (or Spring dev), you bind an expression to filmMono that resolves as the query select film.* from film..... You reference that expression four times, and it's resolved four times, in separate contexts. The ordering of the statements is likely a partially-successful attempt by the lib author to lazily evaluate the expression that you bound locally, such that it's able to batch the four accidentally identical queries. You most likely resolved this by collecting into an actual container, and then mapping on that container instead of the expression bound to filmMono.

            In general, this situation is because the options available to library authors aren't good when the language doesn't natively support lazy evaluation. Because any operation might alter the dataset, the library author has to choose between:

            • A, construct just enough scaffolding to fully record all resources needed, copy the dataset for any operations that need to mutate records in some way, and hope that they can detect any edge-cases that might leak the scaffolding when the resolved dataset was expected (getting this right is...hard).
            • B, resolve each level of mapping as a query, for each context it appears in, lest any operations mutate the dataset in ways that might surprise the integrator (e.g. you).
            • C, as above, except instead of duplicating the original request, just duplicate the data...at every step. Pass-by-copy gets real painful real fast on the JVM, and languages like Clojure and Scala handle this by just making the dev be very specific about whether they want to mutate in-place, or copy then mutate.

            In your case, B made the most sense to the folks that wrote that lib. In fact, they apparently got close enough to A that they were able to batch all the queries that were produced by resolving the expression bound to filmMono (which are only accidentally identical), so color me a bit impressed.

            Many access patterns can be rewritten to optimize for the resulting queries instead. Your milage may vary...wildly. Getting familiar with raw SQL, or else a special-purpose language like GraphQL, can give much more consistent results than relational mappers, but I'm ever more appreciative of good IDE support, and mixing domains like that often means giving up auto-complete, context highlighting, lang-server solution-proofs and linting.

            Given that the scope of the question was "why did this happen?", even noting my lack of familiarity with your stack, the answer is "lazy evaluation in a language that doesn't natively support it is really hard."

            Webflux, with Websocket how to prevent subscribing twice of reactive redis messaging operation
            Asked 2021-Nov-29 at 18:46

            I have a websocket implementation using redis messaging operation on webflux. And what it does is it listens to topic and returns the values via websocket endpoint.

            The problem I have is each time a user sends a message via websocket to the endpoint it seems a brand new redis subscription is made, resulting in the accumulation of subscribers on the redis message topic and the websocket responses are increased with the number of redis topic message subscribtions as well (example user sends 3 messages, redis topic subscriptions are increased to three, websocket connection responses three times).

            Would like to know if there is a way to reuse the same subscription to the messaging topic so it would prevent multiple redis topic subscriptions.
