Asynchronous function queue with adjustable concurrency. This module exports a class Queue that implements most of the Array API. Pass async functions (ones that accept a callback or return a promise) to an instance's additive array methods. Processing begins when you call q.start().

QUESTION
How to publish two messages of the same type to different worker instances based on the message content without using Send and RequestAddress?
My scenario is:
I am using Azure ServiceBus and Azure StorageTables.
I am running two different instances of the same worker service workera and workerb. I need workera and workerb to both consume messages of type Command based on the value of Command.WorkerPrefix.
the Command type looks like:
...ANSWER
Answered 2021-Jun-15 at 23:37Using MassTransit with Azure Service Bus, I would suggest taking the message routing burden away from the publisher, and moving it to the consumer. By configuring the receive endpoint and using a subscription filter each instance would add its own subscription and use a message header to filter published messages.
On the publisher, a message header would be added:

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

Answered 2021-Jun-15 at 18:32Well, 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.
Try to look into a TransactionalOperator and its usage from the Java DSL's fluxTransform():

pushsharp has it on the roadmap to support the new interface but not completed yet.
Found this library which seems easy enough to use as a solution. hope this helps.
QUESTION
I wrote a discord bot. "o" is first letter of play. "atla" is skip. When I wrote -o MUSIC_NAME, music is adding queue and starting to play. And when I write again, just adding queue. Everything is okay still here. When I wrote -atla. It's also working perfectly. But when I allow to changing auto music itself, it's changing music automatically. But problem is here. The end of the last music not working else if (list.length === 0) block in endHandler function. How can I fix that? Thanks for your attention.
...ANSWER
Answered 2021-Jun-15 at 15:41I'm not familiar with Discord bots but I don't think your endHandler will ever run the else if part the way it is because your code is always creating a new dispatcher when it plays the next song, but never sets up a finish handler for it.
QUESTION
In the following code:
...ANSWER
Answered 2021-Feb-27 at 09:23There are 2 separate queues for handling of the callbacks. A macro and a micro queue. setTimeout enqueues an item in the macro queue, while promise resolution - to the micro queue. The currently executing macro task(the main script itself in this case) is executed synchronously, line by line until it is finished. The moment it is finished, the loop executes everything queued in the microtask queue before continuing with the next item from the macro queue(which in your case is the console.log("hello") queued from the setTimeout).
Basically, the flow looks like this:
- Script starts executing.
MacrotaskQueue: [], MicrotaskQueue: [].
setTimeout(() => console.log("hello"), 0);is encountered which leads to pushing a new item in the macrotask queue.
MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [].
Promise.resolve('Success!').then(console.log)is read. Promise resolves toSuccess!immediately andconsole.logcallback gets enqueued to the microtask queue.
MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [console.log('Success!')].
- The script finishes executing so it checks if there is something in the microtask queue before proceeding with the next task from the macro queue.
console.log('Success!')is pulled from the microtask queue and executed.
MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [].
- Script checks again if there is something else in the microtask queue. There is none, so it fetches the first available task from the macrotask queue and executes it, namely -
console.log("hello").
MacrotaskQueue: [], MicrotaskQueue: [].
- After the script finishes executing the
console.log("hello"), it once again checks if there is anything in the microtask queue. It is empty, so it checks the macrotask queue. It is empty as well so everything queued is executed and the script finishes.
This is a simplified explanation, though, as it can get trickier. The microtask queue normally handles mainly promise callbacks, but you can enqueue code on it yourself. The newly added items in the microtask queue will still be executed before the next macrotask item. Also, microtasks can enqueue other microtasks, which can lead to an endless loop of processing microtasks.

I am trying to receive and send simple messages from two web APIs using RabbitMQ. It is a pretty simple code for now, and I am trying to see if both the APIs are properly able to communicate with each other. The issue is that I am not receiving all the messages and unable to establish a pattern between those that I am losing and those I am receiving. Below is the sample code.

I'm implementing a simple task queue using redis in Rust, but am struggling to deserialize the returned values from redis into my custom types.
In total I thought of 3 approches:
- Deserializing using serde-redis
- Manually implementing the
FromRedisValuetrait - Serializing to String using serde-json > sending as string > then deserializing from string
The 3rd approach worked but feels artificial. I'd like to figure out either 1 or 2, both of which I'm failing at.
Approach 1 - serde-redisI have a simple Task definition:
...ANSWER
Answered 2021-Jun-15 at 09:55Redis doesn't define structured serialization formats. It mostly store strings and integers. So you have to choose or define your format for your struct.
A popular one is JSON, as you noticed, but if you just want to (de)serialize simple pairs of (id, description), it's not very readable nor convenient.
In such a case, you can define your own format, for example the id and the description with a dash in between:
