SQL

The SQL adapter allows interaction with a SQL database. This adapter can be configured for either direct SQL queries or in an object-relational mapping configuration. Reference the sample configurations for examples of each mode. Support for SSL/TLS encrypted connections will soon be available.

Properties

Property Name	Type	Description
`host`	String	Required. The IP or hostname of the SQL database.
`port`	Number	Required. The port of the SQL database.
`dbName`	String	The name of the SQL database.
`credentials.user`	String	The username to use when authenticating with the SQL database.
`credentials.passwd`	String	The password to use when authenticating with SQL database.
`direct`	Boolean	A boolean flag indicating whether a direct connection to the database will be established and exposed.
`orm`	Boolean	A boolean flag indicating the object-relational-mapping connection to the database will be established and exposed.
`min`	Number	The minimum number of concurrent connections to open. Only used for ORM connections.
`max`	Number	The maximum number of concurrent connections to open. Only used for ORM connections.
`acquireTimeout`	Number	The number of milliseconds to wait before declaring the attempt to acquire a database connection has failed. Only used for direct connections. Default is 10,000.
`waitForConnection`	Boolean	Determines the behavior of the adapter when no connections are available. Only used for direct connections. Default is `true`. If true, the request will be queued for response when a connection is available. If false, the request will error immediately.
`connectionLimit`	Number	The number of supported concurrent connections. Only used for direct connections. Default is 10.
`queueLimit`	Number	The maximum number of connection requests allowed in the connection queue. Only used for direct connections. Default is 10.

Direct Configuration

A sample configuration for direct SQL queries is provided. Be sure to configure the following properties.

host
port
dbName
credentials.user
credentials.passwd

{
  "id": "mysql",
  "type": "MySQLDriver",
  "properties": {
    "host": "localhost",
    "port": 8888,
    "dbName": "peering_insights",
    "credentials": {
      "user": "pronghorn",
      "passwd": "$ENC87eb897b507afc1796db49409dd026188a832188a7d7439b"
    },
    "direct": true,
    "orm": false,
    "acquireTimeout": 10000,
    "waitForConnection": true,
    "connectionLimit": 10,
    "queueLimit": 10
  }
}

ORM Configuration

A sample configuration for object-relational mapping is provided. Be sure to configure the following properties:.

host
port
dbName
credentials.user
credentials.passwd

{
  "id": "mysql",
  "type": "MySQLDriver",
  "properties": {
    "host": "localhost",
    "port": 8888,
    "dbName": "peering_insights",
    "credentials": {
      "user": "pronghorn",

    "direct": false,
    "orm": true,
    "min": 3,
    "max": 7
  }
}
