Hi, Imagine a (common) situation where you use document routing and you end up with 1 large shards (e.g. 1 large user with lots of docs). Shard splitting will help here, because we can break up that 1 shard in 2 smaller shards (and maybe do that "recursively" to make shards sufficiently small).
But what happens with document routing after a big shard is split? I assume new docs keep going to just one of the 2 new shards, right? If so, does that mean that after a while one of the new shards will balloon again and the above procedure will need to be repeated?
