I dont know how the Pharo Mongo Driver works but if connecting to Mongo Atlas
would require a lot of exploring then could using the mongo C drivers thru
uFFI or some other way be an alternative method to connect to Mongo Atlas
https://docs.mongodb.com/drivers/c/

Hi
can anyone pls help me with an example of connecting to a MongoDB Atlas
cluster (their cloud service).
My Atlas cluster replica set is at the urls
-shard-00-00.x.mongodb.net:27017
-shard-00-01.x.mongodb.net:27017
-shard-00-02.x.mongodb.net:27017
The MongoDB Atlas website specifies the application connectstring as
'mongodb+srv://

I saw the doc / example on pharo-nosql/mongotalk but could not figure
out
in
MongoClient -
1. how to get embed the username:password in the connectstring which i
feel
would be needed,
2. how to specify the default database
3. is it required to specify all three members while Mongo suggests a
single
part connect string which probably must be covering the cluster
thanks

cheers,
Sanjay
