[Reading from secondaries] - Doubt

MongoDB University M201: MongoDB Performance

Hi,

If I have a sharded cluster, but I want to do Analytics on data, is it recommended to read from secondaries or not?

Thank you!

No not advisable


Also please read mongo doumentation and our forums on read/update concerns

Certainly would not be recommended on a sharded system for (I hope) obvious reasons.
