Support EOL for MySQL Connector/J 5.1

Per Oracle’s Lifetime Support policy, as of Feb 9th, 2021, MySQL Connector/J 5.1 series is covered under Oracle Sustaining Support. Downloadable binaries can be found in the MySQL Products Archives and in the Maven Central Repository.

MySQL Connector/J 5.1.49 has been the last release of Connector/J 5.1 series.

It is time to move on. Users are encouraged to upgrade to MySQL Connector/J 8.0 series which provides the same features as Connector/J 5.1 and a lot more, including a brand new date/time handling support, introduced in version 8.0.23, and the X DevAPI that empowers the MySQL Document Store.

We like to hear from you. Please join …

Support for Date-Time Types in Connector/J 8.0

Connector/J version 8.0.23 came out with several bug fixes related to date-time types support. They provide more flexibility for configuring time zone handling and allow migration from Connector/J 5.1 with much less effort.

Problems with migration from Connector/J 5.1 to Connector/J 8.0 were caused by the early decision that Connector/J 8.0 should always try to preserve an instant point on the time-line while Connector/J 5.1 does it optionally and, by default, preserves the original visual representation.

For example, the following code will store different results with Connector/J 5.1 and Connector/J 8.0 in case the client and server time zones are different:

Statement st = conn.createStatement();
st.executeUpdate("CREATE TABLE t1 (ts TIMESTAMP)");

PreparedStatement ps = conn.prepareStatement("INSERT INTO t1 VALUES (?)");
ps.setTimestamp(1, Timestamp.valueOf("2020-01-01 12:00:00"));
ps.executeUpdate();

X DevAPI Traffic Compression With Connector/J

X Protocol traffic compression is available on MySQL Server since version 8.0.19. A connector that also supports compression on its end can leverage this feature and reduce the byte streams that are exchanged with the Server.

By default, connections to a MySQL server are uncompressed, thus permitting exchanging data with a client or connector that doesn’t support compression. However, given a client or connector that also supports compression, it is recommended that client and server negotiate the connection compression by default. If this negotiation concludes successfully, both ends can then compress the data they send.

Compression at this level allows reducing the amount of bytes exchanged over the network, but at the cost of additional CPU resources required to run data inflate and deflate operations. The benefits of compression, therefore, occur primarily on low network bandwidth. One can assess the gain or loss due to the …
