Android Firebase multiple sort

Question

I have a question about firebase sorting.

I have the next database:

{
    \"-Ka8xxTgyFB8yYKH50j_addclose\" : {
        \"number\" : 0,
        \"point\"          


        

Answer 1

You'll need to sort all your data client side as there can only be one orderBy column per query.

If you need to double sort server side you'll have to update your database to have a combined key that would hold both timestamp and point.
