Thanks for the input! I'll mark this as required. |

I think SDAM might be out of scope for the architecture guide. I imagine if we were to add something about the TopologyVersion, it would be in the "Replication and Topology Coordinators" section. For example (additions in bold), It is non-blocking and does a large amount of a node's decision making surrounding replication. Most replication command requests and responses are filled in here." Note, I left featureCompatibilityVersion changes out of this explanation because it also is not covered in the guide yet. |

I think the changes around ToplogyVersion would be helpful to have in the architecture guide and would fit the level of detail that we already have. |

I'm unsure whether to close this ticket. The architecture guide does not currently cover isMaster or SDAM. However, this project does change the TopologyCoordinator to store a TopologyVersion. The TopologyVersion is updated on significant topology changes, e.g. state change, reconfig, featureCompatibilityVersion change. The TopologyVersion is used by isMaster commands to await a significant topology change before returning. pavithra.vetriselvan, samy.lanka@mongodb.com, does this level of detail belong in the architecture guide? |
