    Description

      http://docs.mongodb.org/manual/core/sharding-chunk-splitting/

      This page states: "When a chunk grows beyond the specified chunk size, a mongos instance will split the chunk in half."

      This is not always strictly true. The mongo s will try to split it in half, but supposing you've chosen a shard key with insufficient cardinality, and all data on the chunk has the same shard value, it will never split even though it outgrows 64MB.
