MariaDB Connector/J 3.4.1 is a Stable (GA) release.

Notable Changes

Implementation of pinGlobalTxToPhysicalConnection for XA Connection

For

The new boolean option pinGlobalTxToPhysicalConnection, when enabled, ensures that an operation for a specific XID is routed to the same connection, to permit supporting XA START <xid> when XA END has been called. This prevent errors like

Enhanced host description

For /

The host description for connecting to the server has been changed from either <host>[:<portnumber>] or address=(host=<host>)[(port=<portnumber>)][(type=(master|slave))] to a more detaild host description, permitting to set localsocket or pipe, and to define a specific ssl mode depending on the host. New format:

Example:

This connection string now permits to use a local unix socket if available, and host 10.0.0.1 with ssl if the unix socket is not available. A detailed host description option supersedes a global option description. The previous example can also be written in the following way, defining different ssl modes for both host options:

Adding databaseTerm alias

For

Option useCatalogTerm has an alias databaseTerm for MySQL connector compatibility.

Bugs Fixed

• The validation of a statement of the cache for prepared statements is not taking the use of different schemas into account, which can result in unexpected behavior when the same statement is executed on different schemas.

• DatabaseMetaData.getImportedKeys returns a different PK_NAME value than DatabaseMetaData.getExportedKeys when using a NON UNIQUE constraint.

• Slow performance of function DatabaseMeta.getExportedKeys()
