In case of hardware failure or maintenance, replica sets allow MongoDB to provide automatic failover and data redundancy. For scalability, MongoDB supports horizontal scaling through sharding, which is a way to distribute data across multiple databases on multiple machines. A sharded cluster can ...
What is MongoDB? MongoDB is a non-relational document database that provides support for JSON-like storage. AWS enables you to run MongoDB-compatible workloads with Amazon DocumentDB (with MongoDB compatibility), a fast, scalable, and fully managed non-r
MongoDB uses a Transaction log internally just like many other databases. This is known as an Oplog in MongoDB. This serves as an internal log of every internal operation used for replication in a MongoDB Cluster. Each Replica Set, in a Sharded Cluster, has its own Oplog. ...
Replica set deployment Scalability¶ Ensure your database handles the load as your data set grows without performance degradation. Theshardingmethod in MongoDB is the distribution of data across multiple servers where each server handles a subset of data. This is the horizontal scaling mechanism whe...

MongoDB is asingle-mastersystem—each replica set can have only one primary node that receives all the write operations. All other nodes in the same replica set are secondary nodes that replicate the primary node's operation log and apply it to their own data set. By default, clients also...
