QUESTION
We are working with AWS Glue as a pipeline tool for ETL at my company. So far, the pipelines were created manually via the console and I am now moving to Terraform for future pipelines as I believe IaC is the way to go.
I have been trying to work on a module (or modules) that I can reuse as I know that we will be making several more pipelines for various projects. The difficulty I am having is in creating a good level of abstraction with the module. AWS Glue has several components/resources to it, including a Glue connection, databases, crawlers, jobs, job triggers and workflows. The problem is that the number of databases, jobs, crawlers and/or triggers and their interractions (i.e. some triggers might be conditional while others might simply be scheduled) can vary depending on the project, and I am having a hard time abstracting this complexity via modules.
I am having to create a lot of for_each
"loops" and dynamic blocks within resources to try to render the module as generic as possible (e.g. so that I can create N number of jobs and/or triggers from the root module and define their interractions).
I understand that modules should actually be quite opinionated and specific, and be good at one task so to speak, which means my problem might simply be conceptual. The fact that these pipelines vary significantly from project to project make them a poor use case for modules.
On a side note, I have not been able to find any robust examples of modules online for AWS Glue so this might be another indicator that it is indeed not the best use case.
Any thoughts here would be greatly appreciated.
EDIT: As requested, here is some of my code from my root module:
...ANSWER
Answered 2021-May-24 at 12:52I think I found a good solution to the problem, though it happened "by accident". We decided to divide the pipelines into two distinct projects:
- ETL on source data
- BI jobs to compute various KPIs
I then noticed that I could group resources together for both projects and standardize the way we have them interact (e.g. one connection, n tables, n crawlers, n etl jobs, one trigger). I was then able to create a module for the ETL process and a module for the BI/KPIs process which provided enough abstraction to actually be useful.
QUESTION
I have a Vue/Vuefify project and I'm using the vkbeutify lib to format XML and then display it in the Ace Editor. The Editor opens in a modal dialog (full screen mode) and all works fairly well when the amount of XML is small.
I have to parse about 2.5MB+ of it (about 2,500,000 characters when formatted in Notepad++) and then Ace becomes unusable (it eventually displays the XML, but it takes a very long time).
I created a simple test page with a textarea and the Editor and the formatting and display goes extremely fast. The page does exactly the same thing as this: https://www.webtoolkitonline.com/xml-formatter.html (this uses Ace and vkbeautify to format xml)
I tried pre-formatting the XML in an text area before passing it to the child dialog, tried subverting Vue and populating the editor container in the mounted() function by getting the DOM contents directly.
Standalone test page:
...ANSWER
Answered 2021-Apr-30 at 09:28This happens because you are setting maxLines
to Infinity
, by that disabling virtual screen optimization of the editor. maxLines
is intended for small snippets, less than window height.
QUESTION
Does destructuring assignment (in my case with Vue composables) has any performance gain/tradeoff?
For example I have component that displays current language choosed in vue-i18n.
I can do this with destructuring:
...ANSWER
Answered 2021-Apr-28 at 01:45No, there is no significant performance implication of destructuring. It's really just syntactic sugar that makes code more concise and readable.
EDIT: I'm going to add the remark that you should not in general be worrying about the performance of core language features like this. Worry about which data structure is best for a particular use case, don't worry about what syntax performs best. If you are coding more or less competently, then performance optimization should be a fairly uncommon exercise and not your first consideration. Code for readability and maintainability and only worry about performance when you notice it's a problem or happen to know that it's critical.
QUESTION
I need to sync a moderate amount of data regularly from a service into a local database in Azure.
I could write the code for that and I would have been done with this 10 times over if I did, but where's the fun in that, right?
I thought, let's use some fancy Azure services and see how that goes. It may lead to some better maintainability if I have something workflow and node-based.
So I made an ADF pipeline and a copy job to an Azure Table, which works fine. The json from the service is parsed correctly and I could insert the json fields as table columns.
In a next step I want to copy the data further to a Azure SQL Database and convert some types properly:
- One field is either missing or has one of two fixed string (not "true" or "false" though), and it should be a bit in the database.
- Another field has a very opinionated date format and needs to be parsed properly.
I don't think this works in the copy job. The mapping tab seems to be limited and the dynamic thingie ("add dynamic content" in that tab) appears to not be able to refer to the fields I need to transform.
Am I correct in assuming that I now need to use either a data flow (executed on some Java cluster I believe) or an SSIS package?
I tried creating a data flow, but it appears it can't use Azure Tables as a source - at least that source isn't offered in the respective selector.
Since I'm not even sure that a data flow is necessary, I'm asking for help at this point.
...ANSWER
Answered 2021-Apr-20 at 08:54Yes, as you said, copy activity can't do this and data flow doesn't support Azure table storage. As a workaround, you can copy data from Azure table storage to those supported connector in data flow(such as Azure blob storage), and then use that as source in data flow. Finally do some transformation and sink to Azure SQL Database. Or you can use SSIS package.
QUESTION
It may be opinionated and not belong here, but I don't seem to find any info about this.
I have a 'sales' resource so I can GET, POST, PUT, DELETE sales of my store.
I want to do a dashboard with information about those sales: e.g the average sales per day of the last month.
Since REST is resource-oriented, that means I have to manually retrieve all sales of the last month and calculate the average per day on client using GET /sales?sale_date>=...? That doesn't seem optimal, since I could have thousands of sales in that period of time.
Also, I don't think REST can allow a URL like GET /sales/average-per-day-last-month. What is the alternative of doing this?
...ANSWER
Answered 2021-Mar-28 at 15:58I don't think REST can allow a URL like GET /sales/average-per-day-last-month
Change your thinking - that's a perfectly satisfactory URL for a perfectly satisfactory resource.
Any information that can be named can be a resource -- Fielding, 2000
"Any information that can be named" of course includes "any sales report that you can imagine".
QUESTION
I'm building a site using Laravel 8 and Jetstream. Jetstream is opinionated about the javascript / css framework, which is great, but I'm needing to add an external javascript library to one of my components, and I don't see anywhere to add them in the default app
layout. So I added a stack for the css /js like this in the default app layout:
ANSWER
Answered 2021-Feb-27 at 03:13For anyone banging their head against a similar wall-- the problem with my code is that the push
needs to be inside the layout tag. Once I moved that up, it worked (and I had been using public_path
wrong):
QUESTION
Please do correct me if I'm wrong about anything:
The JS runtime engine agents are driven by an event loop, which collects any user and other events, enqueuing tasks to handle each callback.
The event loop runs continuously and has the following thought process:
- Is the execution context stack (commonly referred to as the call stack) empty?
- If it is, then insert any microtasks in the microtask queue (or job queue) into the call stack. Keep doing this until the microtask queue is empty.
- If microtask queue is empty, then insert the oldest task from the task queue (or callback queue) into the call stack
So there are two key differences b/w how tasks and microtasks are handled:
- Microtasks (e.g. promises use microtask queue to run their callbacks) are prioritised over tasks (e.g. callbacks from othe web APIs such as setTimeout)
- Additionally, all microtasks are completed before any other event handling or rendering or any other task takes place. Thus, the application environment is basically the same between microtasks.
Promises were introduced in ES6 2015. I assume the microtask queue was also introduced in ES6.
My questionWhat was the motivation for introducing the microtask queue? Why not just keep using the task queue for promises as well?
Update #1 - I'm looking for a definite historical reason(s) for this change to the spec - i.e. what was the problem it was designed to solve, rather than an opinionated answer about the benefits of the microtask queue.

ANSWER
Answered 2021-Feb-13 at 22:49One advantage is fewer possible differences in observable behavior between implementations.
If these queues weren't categorized, then there would be undefined behavior when determining how to order a setTimeout(..., 0)
callback vs. a promise.then(...)
callback strictly according to the specification.
I would argue that the choice of categorizing these queues into microtasks and "macro" tasks decreases the kinds of bugs possible due to race conditions in asynchronicity.
This benefit appeals particularly to JavaScript library developers, whose goal is generally to produce highly optimized code while maintaining consistent observable behavior across engines.
QUESTION
I'm doing leetcode questions to get better at solving problems and expressing those solutions in rust, and I've come across a case where it feels like the most natural way of expressing my answer includes unsafe code. Here's what I wrote:
...ANSWER
Answered 2021-Jan-27 at 09:25You should avoid unsafe unless there are 2 situations:
- You are doing something which impossible to do in safe code e.g. FFI-calls. It is a main reason why unsafe ever exists.
- You proved using benchmarks that unsafe provide big speed-up and this code is bottleneck.
Your arguing
I know I could easily do a checked cast and unwrap it, but that feels a bit silly because of how certain I am that the check can never fail.
is valid about current version of your code but you would need to keep this unsafe in mind during all further development.
Unsafe greatly increase cognitive complexity of code. You cannot change any place in your function without keeping unsafe in mind, for example.
I doubt that utf8 validation adds more overhead than possible reallocation in result.insert(0, _1);
in your code.
Other nitpicks:
- You should add a comment in unsafe section which explains why it is safe. It would make easier to read a code for a other people (or other you after a year of don't touching it).
- You could define your constants as
const _0: u8 = b'0';
QUESTION
What is the correct way to require a node module? Is it more accurate/understandable to declare the module in the global scope, or is it more accurate/understandable to declare the module in the local scope?
For example, which of these makes the most sense:
Global:
...ANSWER
Answered 2021-Jan-27 at 02:43First, a minor correction. Your first example is not global scope. That's module scope. Module scope with the declaration located at the beginning of your module file is the preferred implementation for the following reasons:
- It loads at startup (see text below for why that's good).
- Locating all these at the beginning of your module file clearly states in the code what external module dependencies you have in a nice easy to see way which is useful for anyone coming back to this code in the future to do maintenance (including you).
- You only ever
require()
this module once in this module. While modules are cached, it's better to not be callingrequire()
every time you want to reference it. Load it once and use that saved module reference.
About point 1 above, require()
is blocking and synchronous and involves accessing the file system (the first time that file is loaded). You generally want to get all your require()
operations done at server-startup so no blocking operations are happening while you are processing requests. And, if you get any errors from require()
(such as a module install missing or version conflict or bad configuration or missing dependency or something like that), you also want those to happen at startup time, not later where they are quicker to see and easier to diagnose.
QUESTION
I am building a Go service that communicates with multiple third-party providers. This go-service acts as an interface between these multiple providers and my internal applications consume just one API from this Go service.
My application has the below structure now
...ANSWER
Answered 2021-Jan-22 at 10:07First of all, note that this question is opinionated to an extent, and there is no right answer for this.
Personally I like having an cmd/app
, config
sub-directories as they contain the logic of starting/running the app and I feel lie nicely when bundled like that.
For the rest of the app I like having a flat structure, going into sub-directories only if there's heavy coupling. It's important to have a separation of the layer between the handler, database (if there is one), and external APIs (if there are some).
