Use Case

As a... Driver Engineer
I want... to add support for CSOT in CSFLE 
So that... the driver will be compliant with the CSOT spec

User Impact

• N/A: New Feature

Dependencies

• Required CSOT feature

Unknowns

• questions that need to be answered to determine implementation

Acceptance Criteria

Implementation Requirements

• Ensure that remaining timeoutMS is used for timeout in following scenarios
  • executing listCollections command to retrieve collection schemas
  • executing find commands to get data from key vault
  • executing commands against mongocryptd
  • to timeout HTTP requests against KMS server to decrypt data keys
• Ensure that maxTimeMS is not appended to any command when executing against mongocryptd
• Add support for timeoutMS to ClientEncryption
  • Note that the option should not be supported on the individual encryption/decryption apis on ClientEncryption objects, but to be configured once on its construction and have the option be applied to all calls on this object

Testing Requirements

• Implement prose test #2 from CSOT spec
• Implement prose test #3 from CSOT spec
• Implement the following spec unit tests
  • The remaining timeoutMS value should apply to HTTP requests against KMS servers for CSFLE. 
  • The remaining timeoutMS value should apply to commands sent to mongocryptd as part of automatic encryption.
• Add integration tests that verify that the timeoutMS option configured on the ClientEncryption object applies to all APIs listed here

Documentation Requirements

• Document behaviour in NODE-5688
