Subject:MySQL Utilities 1.5.3 has been released
View as plain text  
Dear MySQL users,

MySQL Utilities version 1.5.3 is a GA release for Utilities 1.5. MySQL
Utilities version 1.5.3 is compatible with MySQL Server versions 5.5
and greater. Python v2.6 and v2.7 are supported.

In addition to server utilities, MySQL Utilities also contains
MySQL Fabric: a framework for managing a collection of MySQL servers.
MySQL Fabric is deployed as a separate service daemon that contains
support for high-availability and sharding. MySQL Utilities and Fabric
require Connector/Python 2.0.0 or higher.

The management framework maintains a database of the routing and
state information for the servers making up the system and provides
an easy-to-use command line interface for adding, removing and
organizing servers.

High-availability is provided by continuously monitoring the servers
and executing slave promotion when the master crashes and just as
importantly automatically updates the state and routing information
that gets messages to the right server.

MySQL Fabric comes with built-in support for sharding either using
ranges or consistent hashing and supports the sharding of multiple
tables to ensure that rows with matching sharding keys are stored
in the same shard. MySQL Fabric also contains support for global
tables that are duplicated on all shards as well as the ability to
synchronize schema updates across all of the servers.

To provide high performance and avoid latency, transactions are
directly routed by Fabric-aware connectors rather than routing via
an external proxy. The connectors dispatch transactions to the
correct shard, perform load-balancing, and handle read-write
splitting. Currently there exists Fabric-aware versions of
Connector/Python, Connector/Java, and Connector/PHP (through a
Fabric-aware mysqlnd_ms plugin).

MySQL Utilities v1.5.3 GA is available for download from

A brief summary of changes is listed below. Please check the
CHANGES.txt file inside the distribution for a more complete list
of changes.

Changes in MySQL Utilities 1.5.3 (2014-11-04)

Bugs Fixed

   * The MySQL Fabric installer failed to properly check for
     the required Connector/Python version. (Bug #19807933,
     Bug #74339)

   * Setting up a MySQL Fabric backing store would fail when
     the target MySQL instance used a unicode character set as
     the default. (Bug #19785686, Bug #74192)

   * The MySQLServer object created connections with
     "use_unicode=False", and as a consequence some statements
     returned fields in the bytearray format, as opposed to
     the expected strings or unicode fields. This unexpected
     field data type would sometimes cause problems with
     several modules, such as replication and high
     availability. (Bug #19774543, Bug #74255)

   * MySQL Fabric was improved to support AWS and Trove.
     Changes include no longer assuming that hosts have UUIDs,
     and plugin support was also added. (Bug #19589254)

   * The mysqldbcompare utility options related to comparing
     all databases on two servers were accidentally removed
     (e.g., --all, --exclude, and --regexp in a previous
     release, and they have since been restored.
     Additionally, the error handling and validation routines
     were improved. (Bug #19430737, Bug #73551)


The source distribution includes the manual pages for each utility under
the docs/ folder.
