I need to pass a very large object to my component from service. Since the object is very large i am intending to divide the object into chunks. How can i send the service 'getData()' request at intervals to get the data chunk by chunk? Basically i don't want the data to come from service at once, but in chunks. For instance if data is like this - {'x':'1','y':2,'z':3}, then data to to come for x first, then y and so on. Thanks in advance for any heads up.
In this case RxJs partition operator might help. Assuming 'large object' is nested object with keys you can implement some logic to return in a sequence you want.
const obj = {fist: {name: 'joe', age: 30}, second: {name: 'doe', age: 40}};
//Turn it into iterable
const array = Object.entries(obj);
// make an observable
const source = from(array);
// Logic for how to split, depends on your obj structure
const [under, over] = source.pipe(partition(val => val[1].age < 40));
// result
under.subscribe(a => console.log("Under 30: " + a));
over.subscribe(a => console.log("Over 30: " + a));
