FIFO | Queueing library in Ruby | AWS library

There 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:

1. Script starts executing.

MacrotaskQueue: [], MicrotaskQueue: [].

1. setTimeout(() => console.log("hello"), 0); is encountered which leads to pushing a new item in the macrotask queue.

MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [].

1. Promise.resolve('Success!').then(console.log) is read. Promise resolves to Success! immediately and console.log callback gets enqueued to the microtask queue.

MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [console.log('Success!')].

1. 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.
2. console.log('Success!') is pulled from the microtask queue and executed.

MacrotaskQueue: [console.log("hello")], MicrotaskQueue: [].

1. 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: [].

1. 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.

IMPORTANT UPDATE: re: 2000+ rows, see link in my last comment (for OneDrive template, s.t. expiry, and bottom of this proposal for screenshot of error "too large to import")

fyi: (Office 365 - Excel - fns. such as 'filter' etc., so #Name! will be ubiquitous upon opening this link; however, sharing this should serve as a convenient means to replicate above screenshot in the correct version of Excel)

1. Office 365
2. Adequate space to the right or ability to utilise extra sheet for calcs as req.

High-level | Take-aways

• Relies on 2 additional tables: Qty 'depletion' table (here - G:P) and corresp. Profit Vectors (here - R:Z)

• Compressed representations (2x2 tables, per Summary Tables, here: rows 19:32) could be explored to simplify matters (albeit these are still Work in Progress ['WiP'])

• VB could be attractive alternative too

Low-level | Procedural

1. Single-cell function could not be found without exceptional complication (however, suspect it could be possible e.g. using FilterXML?)
2. Qty label transposes filtered negative quantities (grey shaded, G3: J3)
3. These values are depleted in turn (from left to right, i.e. dependency on having data sorted in ascending order by date (in this depiction, data first sorted by 'fruit' as these are assumed to be independent in the context of the profit calc.)
4. For example, -5 quantity (G3) offset by +10 (B3) to yield +5 which, in turn contributes towards the -35 qty (H3) to yield -30. No further contribution can be made (left to right); next row (5): +20 avail (given), no offset against -5 (G3, already 'reimbursed', so 20 offset against -30 (H4) to yield -10, and so forth.
5. Worksheet set up to accommodate longer list of fruit / profits
6. Result table of residual 'quantities' (~ G:J) applied to price differential to yield 'profit vectors' (R:U) which are summed against corresponding negative quantities to produce Profit score (yellow shaded cells)

I'm not so familiar with Erlang, but, based on how you described your needs, I think you might be able to take the approach of using multiprocessing.Queue and sorting your messages before reading them.

The idea is to have a multiprocessing.Queue (FIFO message queue) for each process. When process A sends a message to process B, process A puts its message along with the message's priority into process B's message queue. When a process reads its messages, it transfers the messages from the FIFO queue into a list and then sorts the list before handling the messages. Messages are sorted first by their priority followed by the time at which they arrived in the message queue.

Here's an example that has been tested with Python 3.6 on Windows.

@Cheatah's sugestion of using poll() worked perfectly. This is the code now with the changes suggested:

containerConcurrency is an argument to the Knative infrastructure indicating how many requests your container can handle at once.

In AWS Lambda and some other Function-as-a-Service offerings, each instance will only ever process a single request. This can be simpler to manage, but some languages (Java and Golang, for example) easily support multiple requests concurrently using threaded request models. Platforms like Cloud Foundry and App Engine support this larger concurrency, but not the "function" model of code transformation.

Knative is somewhere between these two; since you can bring your own container, you can build an application container which is single-threaded like Lambda expects and set containerConcurrency to 1, or you can create a multi-threaded container and set containerConcurrency higher.

A bit messy, but works.

Each release will start from stage 1. Thus we can add a PowerShell task as the first task for stage 1 to check if there are previous in-progress deployments.

In this PowerShell task, we can call this Rest API to check release stage status.

Is there a way to pass different structs to a single class constructor

No, it isn't possible to pass a type as a function argument (and constructors are (special member-) functions).

However, it is possible to pass types as template arguments, and a constructor can be an instance of a function template... Or the class itself can be instance of a class template. For example:

This is just an answer based on what I am able to understand from your question. Please specify and elaborate if this isn't what you want.

You can sort the list and see if the list is the same afterwards:
