Method Details

throwIfPropertiesAreNotAllowed

public static void throwIfPropertiesAreNotAllowed(Set<String> actualProperties,
 Set<String> systemPropertyPrefixes,
 Set<String> allowedProperties)

This method checks against if they are not system properties. A property is regarded as a system property if its name starts with a prefix in . See org.apache.druid.server.initialization.JDBCAccessSecurityConfig for more details.

If a non-system property that is not allowed is found, this method throws an IllegalArgumentException.

tryParseJdbcUriParameters

public static Set<String> tryParseJdbcUriParameters(String connectionUri,
 boolean allowUnknown)

This method tries to determine the correct type of database for a given JDBC connection string URI, then load the driver using reflection to parse the uri parameters, returning the set of keys which can be used for JDBC parameter whitelist validation.

uris starting with MYSQL_PREFIX will first try to use the MySQL Connector/J driver (5.x), then fallback to MariaDB Connector/J (version 2.x) which also accepts jdbc:mysql uris. This method does not attempt to use MariaDB Connector/J 3.x alpha driver (at the time of these javadocs, it only handles the jdbc:mariadb prefix)

uris starting with POSTGRES_PREFIX will use the postgresql driver to parse the uri

uris starting with MARIADB_PREFIX will first try to use MariaDB Connector/J driver (2.x) then fallback to MariaDB Connector/J 3.x driver.

If the uri does not match any of these schemes, this method will return an empty set if unknown uris are allowed, or throw an exception if not.
