will my topic be stored in one broker if I let the partitioner always return 0?

Hello,

I want to keep the order of record in my topic so I created the producer
with a partitioner that always returns 0. I have the following questions


   - will my topic be stored in 1 broker only?
   - If so, which broker does my topic go to?
   - what happens if I change the partitioner later to e.g. random
   partitoner?


Thanks,
