Continuent is pleased to announce that the following new software releases are now available:

• Tungsten Clustering version 6.1.0
• Tungsten Replicator version 6.1.0

Release 6.1.0 is significant in that it introduces MySQL 8 support, along with many new features, stability improvements and bug fixes.

Highlights common to both products:

Improvements, new features and functionality

• Two new utility scripts have been added to the release to help with setting the Replicator position:
  • tungsten_find_position, which assists with locating information in the THL based on the provided MySQL binary log event position and outputs a dsctl set command …

In MySQL 8.0, when using invalid values for date data types, an error is returned. This was not the case in 5.x versions.

Let’s have a look using the table definition of bug 96361:

CREATE TABLE `new_table` (
  `id_table` int(11) NOT NULL AUTO_INCREMENT,
  `text_table` varchar(45) DEFAULT NULL,
  `date_table` date DEFAULT NULL,
  PRIMARY KEY (`id_table`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci

Now we can try the following statement in MySQL 5.7 and MySQL 8.0:

MySQL 5.7.26> SELECT id_table, text_table 
              FROM new_table WHERE date_table = '' OR date_table IS NULL;
Empty set, 1 warning (0.01 sec)

Overview The Skinny

Database Proxies provide a single entry point into MySQL for the calling client applications.

Proxies are wonderful tools to handle various situations like a master role switch to another node for maintenance, or for transparency with read and write connections.

However, when the time comes to perform the switch action, all of the calling clients have been funneled through the proxy, so identification of the calling host from the database itself becomes difficult.

The Problem What is going on?

Let’s illustrate how not knowing the source of a client connection can be an issue for the database administrator…

In the following diagram, three client applications connect to a Tungsten Cluster via the Connector proxy:
