      Description

      Currently MongoS unconditionally retries find commands on network and replica set errors. While this behaviour helps increase availability, there is risk where a storm of poorly constructed and heavy to execute find commands, which get retried could bring down a node of a replica set.

      This ticket is to consider adding a MongoS boolean parameter, which allows customers to opt out of the retry behaviour.
