Database Reference
In-Depth Information
Summary
In this chapter, you learned the basic configuration and concepts of the replication process
and the replica set network. We talked about the basic type of members, including the
primary, secondary, and arbiter members. Then, we learned about the
oplog
collection,
which holds the database changes.
Then, we went through the different kinds of secondary members. Primary 0, hidden, and
delayed members are different types of secondary members. Also, you can find a detailed
description explaining each one with illustrated charts and diagrams.
Moreover, you learned about the
arbiter
nodes that don't store any data but vote in the
election process for a new primary member.
In the next chapter, we will deploy a replica set network from scratch to provide a readily
available MongoDB server.
