How do you deal with slow external APIs?

How do you deal with slow external APIs?

Rather than waiting for a third party service to respond, dispatch a job to fetch the data. You can then respond with stale data from your cache. If there is no data in the cache you can either render a loading message to the user or you can dispatch the job synchronously, which will increase load time.

How do you handle a slow API?

using HTTP cache headers (depending on the API) as application cache. with a distributed memory service like Redis and Memcached….Cache

1. lower latency.
2. less IO calls in background.
3. faster response.
4. less load on the backend.
5. sometimes can also “cover” outage of the servers or the network.

How you would reduce the latency of APIs?

Reducing request latency

1. Sending requests to the closest regional location. To get the best RTT and server throughput performance, send requests from the client to the closest Cloud Healthcare API regional location.
2. Compressing the response body.
3. Sending warmup requests.
4. Sending requests concurrently with HTTP/1.

How much time should an API call take?

A response time of about 0.1 seconds offers users an “instant” response, with no interruption. A one-second response time is generally the maximum acceptable limit, as users still likely won’t notice a delay.

Is REST API expensive?

Here are those prices: REST API: $3.50 monthly per additional million (up to 333 million calls) HTTP API: $1.00 to $1.17 monthly per additional million (up to 300 millions calls, regional) WebSockets API: $1.00 to $1.24 monthly (up to one billion initial requests, regional).

What are tips and tricks to improve web API performance?

In this article, you will learn the tips and tricks of improving the performance of a Web API. Web API is a technology from Microsoft as a part of .NET framework, that enables users to communicate with heterogeneous platforms including website, mobiles, and desktop applications etc.

How does caching improve performance of web API?

So, next time, when the client requests the same information, instead of retrieving the information from the database, it will give the information from the local memory. The main advantage of caching is that it improves performance by reducing the processing burden. We have several ways to implement Caching in web api.

How does web API handle more concurrent requests?

So, to handle more numbers of concurrent HTTP requests, we have to use Async Programming. Asynchronous request handlers operate somewhat differently. When a request comes to the Web API Controller it takes one of its thread pool threads and assigns it to that request.

When does a request come to the web API controller?

When a request comes to the Web API Controller it takes one of its thread pool threads and assigns it to that request. While the process will start executing, the thread will be returned to the thread pool.
