queryShapeHash
What changes in queryShapeHash compared with MongoDB and what your application has to do.
This difference is of the Different kind.
What MongoDB does
It computes queryShapeHash from its own shape of each query.
What TeselaDB does
It matches on most aggregations; on find, count and distinct the shape matches but the hash does not.
What your application has to do
Do not compare queryShapeHash between MongoDB and TeselaDB; compare it within the same cluster.
