The first lossy technique to deal with backpressure is the throttle() operator. This operator lets you propagate the elements emitted by the observable at a certain interval.
This operator is perfect for implementing rate limiting, such as the problem of showing tweets as fast as a human can read.
The throttle() operator has the following signature:
The first parameter is mandatory and the second is optional:
- interval: This is the time interval, in milliseconds, between the emission of data
- scheduler: This is used to propagate the data
The easiest way to show the usage of this operator is to apply it on an observable that already emits elements at a certain rate. We can ...
