How do you handle millions of requests?
Today, I want to talk about how to handle millions of requests during different promotions, rush hours, and just unexpected users flow.
Simple Backend optimizations
- Make sure you are using database connection pooling.
- Inspect your SQL queries and add caching for them.
- Add caching for whole responses.
What is a good requests per second? Average 200-300 connections per second.
How many requests can a load balancer handle? That will run 3000000 get requests processing up to 20000 requests concurrently per each individual server against the Network Load Balancer URL address. Once all the requests are sent the test is completed.
How do you handle a large API call?
Delivering Large API Responses As Efficiently As Possible
- Reduce Size Pagination.
- Organizing Using Hypermedia.
- Exactly What They Need With Schema Filtering.
- Defining Specific Responses Using The Prefer Header.
- Using Caching To Make Response More Efficient.
- More Efficiency Through Compression.
How do you handle millions of requests? – Additional Questions
How can I speed up API requests?
Caching is one of the best ways to improve API performance. If you have requests that frequently produce the same response, a cached version of the response avoids excessive database queries. The easiest way to cache responses is to periodically expire it, or force it to expire when certain data updates happen.
How fast should an API be?
Generally, response time should be fast as possible in the interval of 0.1 – 1 second. However, people can adapt a slower response times, but they will never be happy with a response time greater than 2 seconds. Lesser the response times, better is client satisfaction, lesser costs, higher customer satisfaction.
How do you avoid API rate limits?
Reducing the number of API requests
- Optimize your code to eliminate any unnecessary API calls.
- Cache frequently used data.
- Sideload related data.
- Use bulk and batch endpoints such as Update Many Tickets, which lets you update up to 100 tickets with a single API request.
How do I test API throttling?
1 Answer
- Make a burst of X requests, timing each request (I would use time. time() ). There should be no evidence of throttling in the timing results.
- Make another request and time it. It should be throttled, and that should be evident in the time taken.
What is the difference between rate limiting and throttling?
Rate Limiting and Throttling policies are designed to limit API access, but have different intentions: Rate limiting protects an API by applying a hard limit on its access. Throttling shapes API access by smoothing spikes in traffic.
How do you handle throttling?
To handle throttling at this level, you have these options:
- Set up multiple connections for a single action so that the logic app partitions the data for processing.
- Set up a different connection for each action.
- Change the concurrency or parallelism on a “For each” loop.
Why is throttling important?
The essential benefit of the Throttling pattern is that it allows a system to control both internal and external traffic that might compromise a system’s ability to operate in a safe and predictable manner. Unanticipated bursts in call activity do happen; sometimes by accident; something by nefarious intention.
Why is throttling useful?
What is API Throttling? API throttling allows you to control the way an API is used. Throttling allows you to set permissions as to whether certain API calls are valid or not. Throttles indicate a temporary state, and are used to control the data that clients can access through an API.
What is the API gateway?
An API gateway is an API management tool that sits between a client and a collection of backend services. An API gateway acts as a reverse proxy to accept all application programming interface (API) calls, aggregate the various services required to fulfill them, and return the appropriate result.
What is difference between API and API gateway?
While API Gateways and API management can be used interchangeably, strictly speaking an API gateway refers to the individual proxy server, while API management refers to the overall solution of managing APIs in production which includes a set of API gateways acting in a cluster, an administrative UI, and may even
Is Amazon API free?
With Amazon API Gateway, you only pay when your APIs are in use. There are no minimum fees or upfront commitments. For HTTP APIs and REST APIs, you pay only for the API calls you receive and the amount of data transferred out. There are no data transfer out charges for Private APIs.
What is HTTP API vs REST API?
REST APIs support more features than HTTP APIs, while HTTP APIs are designed with minimal features so that they can be offered at a lower price. Choose REST APIs if you need features such as API keys, per-client throttling, request validation, AWS WAF integration, or private API endpoints.
Is AWS an API?
What is Amazon API Gateway? Amazon API Gateway is an AWS service for creating, publishing, maintaining, monitoring, and securing REST, HTTP, and WebSocket APIs at any scale. API developers can create APIs that access AWS or other web services, as well as data stored in the AWS Cloud .
Why REST is not a protocol?
REST is an architectural style because it relies on simple URLs. It is not a protocol because the protocol is HTTP.
Why is REST API called REST?
A REST API (also known as RESTful API) is an application programming interface (API or web API) that conforms to the constraints of REST architectural style and allows for interaction with RESTful web services. REST stands for representational state transfer and was created by computer scientist Roy Fielding.
Is REST always JSON?
For some, REST means a server that exchanges JSON documents with a client over HTTP. Not only is that not a complete definition, but it’s also not always true. The REST specification doesn’t require HTTP or JSON.
How many types of API are there?
There are four principal types of API commonly used in web-based applications: public, partner, private and composite. In this context, the API “type” indicates the intended scope of use.
