In advance of quarterly planning, write a short report describing progress of the spike. Suggested contents:

• Performance evaluation.
  • Each evaluation has three numbers: baseline mongod perf, SBE command perf, and end-to-end perf with SBE engine enabled.
• Notes on progress of integration:
  • How to use SBE command.
  • How to turn on SBE engine.
  • Which operators / MQL constructs are currently supported in the prototype.
• Risks / complexity of integration.
  • Yielding.
  • Interruptibility.
  • Debuggability.
  • Multi-planning.
  • Change streams.
  • geoNear.
  • Legacy text search and new Atlas $search.
  • Can we actually complete the whole language in a year?
