Documents distributions across shards

Elastic Stack Elasticsearch
1

say there are 99 documents and we have 3 shards for an index.

is it sure that all the 3 shards are going to have 33 documents each?

thanks in advance?

Hey,

no, there is no perfect balancing, so you will have a slight deviation from that perfect case. The idea is, that this will be roughly the case due to the use of using a Murmur3 hash on the id.
