My application is read as well as write-heavy, and I can not figure out how many members my MongoDB replica set must have. What I thought of having was a 5 member replica set, with the following architecture: 1 primary 2 secondary 1 hidden (for backups) 1 arbiter
I think this should be sufficient to handle the load, however, I still don't have a concrete idea on how to go about designing a replica set. I haven't found anything useful online, and could use some help. Thank you!
