Data Types Agile Development
• Unstructured data • Iterative
• Semi-structured data • Short development cycles
• Polymorphic data • New workloads
Volume of Data New Architectures
• Petabytes of data • Horizontal scaling
• Trillions of records • Commodity servers
• Tens of millions of queries per second • Cloud computing

17. Replication - Summary
• Automatic Failover
• Automatic Recovery
• All writes to primary node
• Rolling Outages are possible, zero downtime

18. Sharding
Scaling

19. Why Shard Data?
Some common reasons:
• Scales Read/Write capacity
• Increases total RAM, to keep the working dataset in physical
memory, for maximum performance
• Shards can be located in specific geographies, for
compliance and/or performance
19

20. How Sharding Works
mongoS: A software switch that routes application
requests to the data. Typically, this will be installed
with the App Server(s).
Config server: Stores metadata on data location.
Sharded deployments should deploy at least 3 config
servers (for redundancy).
20

21. Adding a Shard
To add a shard, spin-up more
mongoDB instances and tell the
mongoS that they are there with a
simple command.
When first moving from a single replica
set to a sharded environment, 50% of
the data moves from Shard 1 to Shard
2.
This puts load on to the system.

“Relational databases have a sound approach, but that doesn’t necessarily match the way we see our data.
mongoDB gave us the flexibility to store data in the way that we understand it as opposed to somebody’s
theoretical view.”
