Question

sh.splitFind () Splits the chunk that contains the shard key value specified by the query at the chunk’s ______ point.

(a) smean

(b) stdev

(c) median

(d) all of the mentioned

This question was posed to me during an internship interview.

The origin of the question is Sharded Cluster Maintenance in section Sharding Concepts, Mechanics and Sharded Cluster of MongoDB

Answer 1

Correct option is (c) median

To explain I would say: It may be beneficial to pre-split manually an empty collection using methods such as sh.splitFind().
