Return large volumes of data in REST API

Question

I am developing REST APIs for mobile apps; we have a web app, which doesn't filter large volumes of meta data. Apps are taking more time to parse these high volume of (2k records with 5 columns) metadata. What are the best ways to handle this scenario from both API & App perspective. API options are preferred..

App devs are asking to return database (sql lite, etc) by combining all the metadata routes and initial sync into a single route.. I am not finding much pointer around this.. is this a practice in industry?

Answer 1

You can think of using asynchronous streaming to send large data to front end and change the client to consume the stream
