|

|
|
This path configures the connection string used to connect to MySQL.
|
||
|
|
The value of the string is a Data Source Name (DSN). An example is
|
||
|
|
using "username:password@protocol(address)/dbname?param=value"
|
||
|
|
|
||
|
|
For example, RDS may look like: "id:password@tcp(your-amazonaws-uri.com:3306)/dbname"
|
||
|
|
|
||
|
|
When configuring the connection string, the backend will verify its validity.
