Hi, I'm Frank from ArangoDB. You should create a number of shards that is much higher than your initial number of servers. ArangoDB can cope with multiple shards per server. This way, you can easily redistribute shards when adding new servers.

Thank you for the answer. I'm currently dealing with an inflow of about one million documents a day; it's an ever growing collection (grows by a few TB each year). Should I just configure it with 1000 shards? Or would it perform bettet with fewer shards?

yes, using 1000 shards would work. Eventually, we will also support splitting shards.

Thank you, that was the answer I was hoping for.
