Number of open connections

[vella-nicholas]

Am I right to understand that the number of open simultaneous connections is set only from the connection string?

If I load hundreds of grains at once, will every initialization try and open a connection per initialization unless I set up a connection limit in the connection string?

No, there is a default value: https://docs.mongodb.com/v3.6/reference/connection-string/#connection-pool-options
