|
|
This path configures the standard connection string (URI) used to connect to MongoDB.
|
|
|
|
A MongoDB URI looks like:
|
|
"mongodb://[username:password@]host1[:port1][,host2[:port2],...[,hostN[:portN]]][/[database][?options]]"
|
|
|
|
See https://docs.mongodb.org/manual/reference/connection-string/ for detailed documentation of the URI format.
|
|
|
|
When configuring the connection string, the backend will verify its validity.
