golang - How to make reads evenly distributed to each secondary when go connects to mongo replica set?

Question

replicaset has two secondary, Eventual mode, but when using labix/mgo.v2 to connect to mongo, it is found that all reads are only concentrated on one secondary, and only a small amount accesses the other secondary.

// Read preference modes are specific to mgo:
Eventual  Mode = 0 // Same as Nearest, but may change servers between reads.
Monotonic Mode = 1 // Same as SecondaryPreferred before first write. Same as Primary after first write.
Strong    Mode = 2 // Same as Primary.

Answer 1

1. Check the connect URL settings;

2. If the Load Balance read is different from the expectations of the parameters you set, you can consider setting the Tag to further configure which member to read from.

For reference.
