MongoDB load balancing

Question

I was looking at best load balancing option for concurrent users with Mongo DB. I have looked at Master Slave replication but don't think this will load balance. Are there any open source DB load balancers for Mongo DB?

I have looked at Sequoia but looks like that project is no longer actively supported.

Please note: The data is not very huge & also not use case for sharding.

Answer 1

both Master Slave and Replica Sets will load balance in MongoDB, if you set slaveOK in your driver.

When slaveOK is enabled MongoDB drivers direct all reads to secondaries/slaves.

This provides relatively effective read balancing; for write balancing your only option.would be sharding.
