abstract class JdbcConnectionProvider extends AnyRef
::DeveloperApi:: Connection provider which opens connection toward various databases (database specific instance needed). If any authentication required then it's the provider's responsibility to set all the parameters. Important to mention connection providers within a JVM used from multiple threads so adding internal state is not advised. If any state added then it must be synchronized properly.

Abstract Value Members
- abstract def canHandle(driver: Driver, options: Map[String, String]): Boolean
Checks if this connection provider instance can handle the connection initiated by the driver.
Checks if this connection provider instance can handle the connection initiated by the driver. There must be exactly one active connection provider which can handle the connection for a specific driver. If this requirement doesn't met then
IllegalArgumentExceptionwill be thrown by the provider framework.- driver
Java driver which initiates the connection
- options
Driver options which initiates the connection
- returns
True if the connection provider can handle the driver with the given options.
- abstract def getConnection(driver: Driver, options: Map[String, String]): Connection
Opens connection toward the database.
Opens connection toward the database. Since global JVM security configuration change may needed this API is called synchronized by
SecurityConfigurationLockto avoid race.- driver
Java driver which initiates the connection
- options
Driver options which initiates the connection
- returns
a
Connectionobject that represents a connection to the URL
- abstract val name: String
Name of the service to provide JDBC connections.
Name of the service to provide JDBC connections. This name should be unique. Spark will internally use this name to differentiate JDBC connection providers.
