I have a list that currently has around 18,000 items. will my rest query continue to work once it breaks the 20,000 mark?
I found this similar question for when the limit was 5k: Approaches for using REST API on list with more than 5K items
it has a comment on the answer : For example, you may have a list of 5k+ items and caml filter query on a none-indexed column. This filter query returns only one single item from the 5k+ list. And you will be throttled by SharePoint and will get a throttle exception. Correct statement - if your operation involves more than 5k items you will be throttled
can I infer from that if all columns that the REST query uses have indexed it will be OK? If any of the columns do not have indexes it will not work?
