MongoDB Clustering or sharding

Hi there,
How to configure clustering in Percona server for MongoDB…?

Hi,
Can you elaborate on what kind of clustering do you mean?
In terms of setting up replica sets or sharding, it’s exactly the same as the regular MongoDB community edition.
A good introduction can be found here: The Anatomy of a MongoDB Replica Set - Percona Database Performance Blog

Hi @przemek
I mean clustering without shards.

Then I suggest starting with What Is Replication In MongoDB? | MongoDB
