- 4. © SpringPeople Software Private Limited, All Rights Reserved. MongoDB Concepts Database • A single MongoDB server can have many databases Collections • Collections are a group of Documents (sort of like RDBMS tables) Documents • A record in a MongoDB collection with a maximum size of 16MB Fields • One name-value pair in a document & is analogous to columns in a relational database

- 10. © SpringPeople Software Private Limited, All Rights Reserved. Replication – Oplogs and Heartbeat • Oplog – Capped Collections that is present in a database called local on every replicating node – Location: Database: local, Collection: oplog.rs – Changing the oplog size (via mongod config) • Heartbeat – A 2-second ping with other members that helps the replica set determine if a node has gone down
- 11. © SpringPeople Software Private Limited, All Rights Reserved. Authentication • Adding the admin user • Adding individual users • Starting the server with auth enabled • Using authentication • Replica sets and authentication
- 12. © SpringPeople Software Private Limited, All Rights Reserved. Sharding • Idea of sharding • How is sharding different from replication? • The different servers involved – Shards – Routers – Config Servers • Sharding without replication • Sharding with replication • Sharding with security enabled • Bad shard keys • Choosing ideal shard keys
- 13. © SpringPeople Software Private Limited, All Rights Reserved. Backup, Repair, Import, Export • Backing up the data directory • Issue with backing up the data directory • Using fsync and lock • mongodump • mongorestore • Bsondump • mongoimport • mongoexport
