## TL;DR

Use the collection query() method with an expression that matches everything. Note this loads all ids into memory, so for very large collections page through with offset and limit instead of one giant query.

## Steps

1. Use the collection query() method with an expression that matches everything. For a collection named 'aaa' with an int64 'id' field: collection = Collection('aaa'); result = collection.query(expr='id >= 0'). That returns every entity, and you can pull just the ids out of the result list. Note this loads all ids into memory, so for very large collections page through with offset and limit instead of one giant query.
