      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      Use Case

      As a Node.js Driver engineer
      I want to spread CPU intensive work across event loop ticks
      So that Node.js applications remain as responsive as possible

      User Impact

      • Currently the driver parses all BSON at once. The goal is to experiment with parsing only the BSON needed for driver functionality (ok:1/0, errmsg, cursor.id) and parse the rest (firstBatch, nextBatch) as a cursor is iterated.

      Acceptance Criteria

      Implementation Requirements

      • PoC parsing partial cursor results and parsing the user data as we iterate
      • Measure the performance effects of this change
      • Answer the following:
        • What are the performance gains?
        • How much BSON "parsing" logic belongs in the driver vs in BSON?

      Testing Requirements

      • Existing tests to ensure no regressions
      • Unit test conditions that enable partial parsing (only occurs for specific cursor commands)

      Documentation Requirements

      • None
