The Future Of Data Engineering In A Post Ai World

The Future Of Data Engineering Services Saxon The class template std::future provides a mechanism to access the result of asynchronous operations: an asynchronous operation (created via std::async, std::packaged task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. the creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std. Blocks until the result becomes available. valid() == true after the call. the behavior is undefined if valid() == false before the call to this function.

The Future Of Data Engineering A New Dawn With Generative Ai The function template std::async runs the function f asynchronously (potentially in a separate thread which might be a part of a thread pool) and returns a std::future that will eventually hold the result of that function call. The get member function waits (by calling wait ()) until the shared state is ready, then retrieves the value stored in the shared state (if any). right after calling this function, valid () is false. if valid () is false before the call to this function, the behavior is undefined. If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. this function may block for longer than timeout duration due to scheduling or resource contention delays. the standard recommends that a steady clock is used to measure the duration. I'm confusing myself with difference between a std::future and a std::promise. obviously, they have different methods and stuff, but what is the actual use case? is it?: when i'm managing some async.

I'm confusing myself with difference between a std::future and a std::promise. obviously, they have different methods and stuff, but what is the actual use case? is it?: when i'm managing some async. A future represents the result of an asynchronous operation, and can have two states: uncompleted or completed. most likely, as you aren't doing this just for fun, you actually need the results of that future to progress in your application. you need to display the number from the database or the list of movies found. The promise is the "push" end of the promise future communication channel: the operation that stores a value in the shared state synchronizes with (as defined in std::memory order) the successful return from any function that is waiting on the shared state (such as std::future::get). Unlike std::future, which is only moveable (so only one instance can refer to any particular asynchronous result), std::shared future is copyable and multiple shared future objects may refer to the same shared state. access to the same shared state from multiple threads is safe if each thread does it through its own copy of a shared future object. The class thread represents a single thread of execution. threads allow multiple functions to execute concurrently. threads begin execution immediately upon construction of the associated thread object (pending any os scheduling delays), starting at the top level function provided as a constructor argument. the return value of the top level function is ignored and if it terminates by throwing.
