                                 throws SQLException

Description copied from class: ConnectionFactory

Implementation of ConnectionFactory.openConnection(com.amazon.redshift.util.HostSpec[], java.lang.String, java.lang.String, java.util.Properties, com.amazon.redshift.logger.RedshiftLogger) for a particular protocol version. Implemented by subclasses of ConnectionFactory.

Specified by:

openConnectionImpl in class ConnectionFactory

Parameters:

hostSpecs - at least one host and port to connect to; multiple elements for round-robin failover

user - the username to authenticate with; may not be null.

database - the database on the server to connect to; may not be null.

info - extra properties controlling the connection; notably, "password" if present supplies the password to authenticate with.

logger - the logger to log the entry for debugging.

Returns:

the new, initialized, connection, or null if this protocol version is not supported by the server.

Throws:

SQLException - if the connection could not be established for a reason other than protocol version incompatibility.
