Preserve Order While Batching Requests

MediumPython

Problem

Given this specific constraint, how would you rewrite this module to handle increased throughput?

Implement batch_requests(requests, batch_size) so each request is processed at most once, first-seen order is preserved, and every output batch contains no more than batch_size requests. Return an array of batches containing the unique requests. The input is an array of integers and a positive integer batch size.

Constraints

  • 1 <= requests.length <= 100000
  • 1 <= batch_size <= 100000
  • Each request is an integer
  • The output must preserve the first occurrence order
  • Duplicate requests must appear at most once in the output

Function Signature
