This version is a bugfix / performance improvement release.

Notable changes and additions

Complete implementation of fetch size

JDBC allows specifying the number of rows fetched for a query, and this number is referred to as the fetch size. Before version 1.4.0, queries were loading all results or row by row using Statement.setFetchSize(Integer.MIN_VALUE). Now it's possible to set the fetch size according to your needs. Loading all results for large result sets uses a lot of memory. This functionality permits saving memory without a performance decrease.

Memory footprint improvement

- Buffers have been optimized to reduced memory footprint

CallableStatement performance improvement

- Calling function / procedure performance is now optimized according to the query. Depending on the queries, the difference can be up to 300%.

Authentication evolution

Permit new authentication possibilities : , and GSSAPI/SSPI authentication.

The GSSAPI/SSPI authentication plugin for MariaDB permits passwordless login.

On Unix systems, GSSAPI is usually synonymous with Kerberos authentication. Windows has a slightly different but very similar API called SSPI that, along with Kerberos, also supports NTLM authentication.

See more details at:

Connection attributes

- Driver information is now sent to (performance_schema must be activated). A new option "connectionAttributes" permits adding client-specific data.

For example when connecting with the following connection string "jdbc:mysql://localhost:3306/testj?user=root&connectionAttributes=myOption:1,mySecondOption:'jj'", if performance_schema is activated, information about this connection will be available during the time this connection is active :

Minor evolution

• : adding a "jdbcCompliantTruncation" option to force truncation warning as an SQLException.

• : when in master/slave configuration, option "assureReadOnly" will ensure that slaves are in read-only mode ( forcing transaction by a query "SET SESSION TRANSACTION READ ONLY").

• : new option "continueBatchOnError". Permit to continue batch when an exception occur : When executing a batch and an error occur, must the batch stop immediatly (default) or finish remaining batch before throwing exception.

Bugfix

• : Using a parametrized query with a smallint -1 does return the unsigned value

• : Tomcat doesn't stop when using Aurora failover configuration

• : handle server configuration autocommit=0

• : ResultSet.first() may throw SQLDataException: Current position is before the first row
