fetches | Rails plugin to simplify the fetching and memoization | Object-Relational Mapping library

I have having 3 error about the object cant be assigned to parameter including int, string and double . I'm trying to fetch data to create a chart-bar to display and process the data.it fetches from another widget called Transaction.

I'm trying to apply some SQL optimization for GraphQL queries containing relations. I use Prisma (v. 2.24.1), Nexus (v. 1.0.0), nexus-plugin-prisma (v. 0.35.0) and graphql (v. 15.5.0).

Hey, I am working on putting up a rocket rest api with a mongodb database.

I have been able to create a successful connection to the MongoDB Atlas and put the resulting client into the state management of rocket via the manage builder function like this:

Assume we have a redis set with hundreds thousands elements in it. As smember command does eager-loading, it fetches all of the elements just by this one command and consequently it consumes too much time. I want to know is there a way to read redis data as bulks or maybe as a stream?

It excites me to see rxjs observables in action and it confuses every single time, but each time I fell more in love with them.

Well, I have three observables -

1. an observable that refreshed based on timer this.autoRefreshView$
2. a default observable that fetches based on today date this.intraDayView
3. an observable that fetches based on yesterday's date (let's say) this.priorDayView$

There is a BehaviourSubject<> that emits if default observable view is to be fetched (based on current date) or yesterday's view based on a view property - today or yesterday.

I want to execute this.autoRefreshView$ only when emitted value is today. But, below it's executed if value is yesterday as well. Is my merge here incorrect? Following is what I tried -

Hello All! I am trying to implement a cart for a simple website that fetches from an API. So my render method looks something like this...

I'm trying to fetch data from my Strapi GraphQl api and paginate them. For that I need to pass down variables. I'm using react-query and fetch api.

Here I declare my variables and query.

I'm running a hour long computation that fetches an external API, process it and save to a dataframe. The API is using Python's request library.

By tweaking the request lib, I managed to fend off problems related to retries and reading errors, but not all possible problems are handled, of course.

Everytime the API fails, my computation just stops, and I lose one hour worth of work.

I'm calling dask like this:

According to the libevent book:

Deferred callbacks

By default, a bufferevent callbacks are executed immediately when the corresponding condition happens. (This is true of evbuffer callbacks too; we’ll get to those later.) This immediate invocation can make trouble when dependencies get complex. For example, suppose that there is a callback that moves data into evbuffer A when it grows empty, and another callback that processes data out of evbuffer A when it grows full. Since these calls are all happening on the stack, you might risk a stack overflow if the dependency grows nasty enough.

To solve this, you can tell a bufferevent (or an evbuffer) that its callbacks should be deferred. When the conditions are met for a deferred callback, rather than invoking it immediately, it is queued as part of the event_loop() call, and invoked after the regular events' callbacks.

As described above:

1. The event loop fetches a batch of events, and processes them one by one immediately.
2. Before the fetched events are processed, any new event won't be fetched and processed.
3. If an event was marked as BEV_OPT_DEFER_CALLBACKS, then it will be processed after all other events in the same batch are processed.

Provided two callbacks ca and cb. First, ca is called, ca finds evbuffer_A is empty, then writes a message into it.

Then, cb is called, and cb finds evbuffer_A contains a message, then fetch and send it out.

When cb is called, ca's stack has been released. I think there won't be a stack overflow in such a scenario.

So, my question is:

What's the purpose of deferred callbacks in libevent?
