Hi @kwx4957 can you perform a benchmarking test to check how these changes have affected the API latency? You can use a mongo compass to run the mongo pipelines and check the latencie==y.

Otherwise the changes look good to me! 🚀

@Saranya-jena Thank you for informing me about the tool I wasn't aware of. yes I will run a benchmarking test.
