No. As the term says, readPreference
only sets the preferred server to read from in the cluster. You can only write to primary servers in a replica set.
Is write operations go to secondary when i set readpreference as secondary in mongodb?

I have replication set up (localhost:27017(primary),localhost:27018(secondary),localhost:27019(arb))
I have set the readPrefrence as secondary in connection lever like below mongoInstance.setReadPreference(ReadPreference.secondary());
When i save some data through this connection will request rout to primary?
how do i confirm this?
I have seen DBCollection coll = getCollection();
coll.getStats();
enter code here
In this "serverUsed":"localhost:27018" has shown.

It doesn't read from a primary, read preference secondary means exactly this, it doesn't disturb primary ever.
