A comma-delimited list of user-defined key:value pairs (in addition to standard MySQL-defined key:value pairs) to be passed to MySQL Server for display as connection attributes in the PERFORMANCE_SCHEMA.SESSION_CONNECT_ATTRS table. Example usage: connectionAttributes=key1:value1,key2:value2 This functionality is available for use with MySQL Server version 5.6 or later only. Earlier versions of MySQL Server do not support connection attributes, causing this configuration option to be ignored. Setting connectionAttributes=none will cause connection attribute processing to be bypassed, for situations where Connection creation/initialization speed is critical.
Since Version 5.1.25
A comma-delimited list of classes that implement "com.mysql.cj.jdbc.interceptors.ConnectionLifecycleInterceptor" that should notified of connection lifecycle events (creation, destruction, commit, rollback, setting the current database and changing the autocommit mode) and potentially alter the execution of these commands. ConnectionLifecycleInterceptors are "stackable", more than one interceptor may be specified via the configuration property as a comma-delimited list, with the interceptors executed in order from left to right.
Since Version 5.1.4
Load the comma-delimited list of configuration properties before parsing the URL or applying user-specified properties. These configurations are explained in the 'Configurations' of the documentation.
Since Version 3.1.5
Comma-delimited list of classes that implement com.mysql.cj.protocol.AuthenticationPlugin and which will be used for authentication unless disabled by "disabledAuthenticationPlugins" property.
Since Version 5.1.19
The name of a class that implements the com.mysql.cj.jdbc.ClientInfoProvider interface in order to support JDBC-4.0's Connection.get/setClientInfo() methods
Default Value com.mysql.cj.jdbc.CommentClientInfoProvider Since Version 5.1.0
Creates the database given in the URL if it doesn't yet exist. Assumes the configured user has permissions to create databases.
Default Value false Since Version 3.1.9
MySQL uses the term "schema" as a synonym of the term "database," while Connector/J historically takes the JDBC term "catalog" as synonymous to "database". This property sets for Connector/J which of the JDBC terms "catalog" and "schema" is used in an application to refer to a database. The property takes one of the two values CATALOG or SCHEMA and uses it to determine (1) which Connection methods can be used to set/get the current database (e.g. setCatalog() or setSchema()?), (2) which arguments can be used within the various DatabaseMetaData methods to filter results (e.g. the catalog or schemaPattern argument of getColumns()?), and (3) which fields in the ResultSet returned by DatabaseMetaData methods contain the database identification information (i.e., the TABLE_CAT or TABLE_SCHEM field in the ResultSet returned by getTables()?).
If databaseTerm=CATALOG, schemaPattern for searches are ignored and calls of schema methods (like setSchema() or get Schema()) become no-ops, and vice versa.
Default Value CATALOG Since Version 8.0.17
Name of a class implementing com.mysql.cj.protocol.AuthenticationPlugin which will be used as the default authentication plugin (see below). It is an error to use a class which is not listed in "authenticationPlugins" nor it is one of the built-in plugins. It is an error to set as default a plugin which was disabled with "disabledAuthenticationPlugins" property. It is an error to set this value to null or the empty string (i.e. there must be at least a valid default authentication plugin specified for the connection, meeting all constraints listed above).
Default Value com.mysql.cj.protocol.a.authentication.MysqlNativePasswordPlugin Since Version 5.1.19
Should the driver detect custom charsets/collations installed on server (true/false, defaults to 'false'). If this option set to 'true' driver gets actual charsets/collations from server each time connection establishes. This could slow down connection initialization significantly.
Default Value false Since Version 5.1.29
Comma-delimited list of classes implementing com.mysql.cj.protocol.AuthenticationPlugin or mechanisms, i.e. "mysql_native_password". The authentication plugins or mechanisms listed will not be used for authentication which will fail if it requires one of them. It is an error to disable the default authentication plugin (either the one named by "defaultAuthenticationPlugin" property or the hard-coded one if "defaultAuthenticationPlugin" property is not set).
Since Version 5.1.19
If "disconnectOnExpiredPasswords" is set to "false" and password is expired then server enters "sandbox" mode and sends ERR(08001, ER_MUST_CHANGE_PASSWORD) for all commands that are not needed to set a new password until a new password is set.
Default Value true Since Version 5.1.23
Set the CLIENT_INTERACTIVE flag, which tells MySQL to timeout connections based on INTERACTIVE_TIMEOUT instead of WAIT_TIMEOUT
Default Value false Since Version 3.1.0
What character encoding is used for passwords? Leaving this set to the default value (null), uses the value set in "characterEncoding" if there is one, otherwise uses UTF-8 as default encoding. If the password contains non-ASCII characters, the password encoding must match what server encoding was set to when the password was created. For passwords in other character encodings, the encoding will have to be specified with this property (or with "characterEncoding"), as it's not possible for the driver to auto-detect this.
Since Version 5.1.7
An implementation of com.mysql.cj.conf.ConnectionPropertiesTransform that the driver will use to modify URL properties passed to the driver before attempting a connection
Since Version 3.1.4
Should the driver issue a rollback() when the logical connection in a pool is closed?
Default Value true Since Version 3.0.15
Don't set the CLIENT_FOUND_ROWS flag when connecting to the server (not JDBC-compliant, will break most applications that rely on "found" rows vs. "affected rows" for DML statements), but does cause "correct" update counts from "INSERT ... ON DUPLICATE KEY UPDATE" statements to be returned by the server.
Default Value false Since Version 5.1.7
