What is the most common practice in retrieving large amounts of data such as usernames, from firebase to parse to check for availability?

Question

Currently I am pulling them all into an array to parse, but I do not feel that will be as advisable when the user count starts exceeding a certain threshold.

Rather than retrieving the data and downloading it to the client, I recommend using Cloud Functions for Firebase. That way, the data remains private and can be processed quickly. See an answer I gave to this question before here.

Also check out these resources to get started with Cloud Functions for Firebase:
