On this page you recommend three member replica sets. However earlier on you recommend:
See https://docs.mongodb.com/manual/core/replica-set-architectures/ for the earlier recommendation. |

Like it. |

joe.drumgoole I've rephrased the paragraph in question to lead with the better option and emphasize that three data-bearing members is the way to go. If you'd like to have a look at the code review, I'd be most obliged! Here's the link: https://mongodbcr.appspot.com/99750001/ |

A 2+1 replica set (2 data nodes, on arbiter). A 2+1 arbiter configuration is less safe than a three node config. We need to decide what we recommend, low cost but unsafe or higher cost but keeps the data safe. We are recommending two different things on two different pages but the worst option is the first one customers come across. |

joe.drumgoole Thanks for your ticket! At the bottom of the Replica Set Architectures page, we link to the Three Member Replica Sets page with a caption that reads "Three-member replica sets provide the minimum recommended architecture for a replica set." The 3-member rs page then describes two deployments: two data-bearing members and an arbiter, and three data-bearing members. This is consistent with the sentence you quoted from the Replica Set Members page As such, I don't think we're being contradictory. However, it's very possible I've missed something, so please let me know if that's the case! |
