Compare and Synchronize Databases with MySQL Utilities

Chuck Bell — Wed, 09 May 2012 20:25:02 +0000

The mysqldiff and mysqldbcompare utilities were designed to produce a difference report for objects and in the case of mysqldbcompare the data. Thus, you can compare two databases and produce a report of the differences in both object definitions and data rows.

While that may be very useful, would it not be much more useful to have the ability to produce SQL commands to transform databases? Wait no longer! The latest release of MySQL Utilities has added the ability to generate SQL transformation statements by both the mysqldiff and mysqldbcompare utilities.

To generate SQL transformations in either utility, simply use the --sql option to tell the utility to produce the statements.

Object Transformations with mysqldiff

If you would like to compare the schema of two databases (the objects and their definitions), mysqldiff can do that for you and produce a difference report in a number of formats including CSV, TAB, GRID, and Vertical (like the mysql client’s \G option).

However, its greatest feature is the ability to generate transformation statements to alter the objects so that they conform. Best of all, mysqldiff works on all object types including the ability to recognize renames so you can get a true transformation path for all objects. For even greater flexibility, you can generate the difference in both directions. This means you can generate transformations for db1-to-db2 as well as db2-to-db1 in the same pass. Cool.

The following shows an example of running mysqldiff on two servers where some of the objects have diverged. It also shows how you can generate the reverse transformation statements.

$ mysqldiff --server1=root@localhost --server2=root@otherhost \
--changes-for=server1 --show-reverse util_test:util_test \
--force --difftype=SQL
# server1 on localhost: ... connected.
# server2 on localhost: ... connected.
# WARNING: Objects in server1.util_test but not in server2.util_test:

#
# ALTER VIEW util_test.v1 AS
# select `util_test`.`t1`.`a` AS `a` from `util_test`.`t1`;
#
Compare failed. One or more differences found.

Generating Data Transformation with mysqldbcompare

The mysqldbcompare utility provides all of the object difference functionality included in mysqldiff along with the ability to generate transformation SQL statements for data. This means you can make sure your test or development databases are similar to your production databases or perhaps even your offline, read only databases match your online databases. Like mysqldiff, you can also get the reverse transformations at the same time. Very cool, eh?

The following shows an example of running mysqldbcompare to generate differences in data.

$ mysqldbcompare --server1=root@localhost --server2=root@otherhost \

inventory:inventory -a --difftype=sql --changes-for=server1 \

--show-reverse

# server1 on localhost: ... connected.

# server2 on localhost: ... connected.

MySQL Utilities Frequently Asked Questions

Chuck Bell — Wed, 09 May 2012 20:13:32 +0000

Momentum for MySQL Utilities continues to build. I hosted a webinar recently about MySQL Utilities (available on-demand from the link below), which generated a lot of interest and some good questions.

http://dev.mysql.com/doc/workbench/en/mysql-utilities.html

General

Are these utilities present in the community version of MySQL?

They are included in the community edition of the MySQL Workbench product, which can be downloaded from the following link.

http://www.mysql.com/downloads/workbench/

Should/can we run this on live data?

Yes. Naturally, you would want to test some operations before jumping directly into a production environment. For example, you may want to test any database migration, transformation, or similar massive change in a test environment.

Can we use the utilities in a production environment under the GPL license?

Yes. MySQL Utilities is part of MySQL Workbench so all such licenses apply accordingly.

Storage Engines

Can the utilities be used with MyISAM or CSV?

Yes. There are no storage engine specific limitations in using the utilities. There are some features written specifically for InnoDB so those may not apply but in general no utility is storage engine specific. For example, the mysqldiskusage utility shows exact sizes for MyISAM and InnoDB files but uses estimated sizes for any other storage engine based on number of rows and row size.

Platforms

Can I use MySQL Utilities on Linux?

Yes. MySQL Utilities runs on all platforms supported by MySQL Workbench.

Can the utilities be used on Windows?

Yes!

Do the utilities work both for window-based and linux-based servers?

Yes! They work for any server hosting MySQL.

Installation

Do we have to install the utilities with rpm or can we use the tar ball extract and run from there?

MySQL Utilities is installed as part of MySQL Workbench. You can download and install Workbench using several platform-specific installers.

You can also branch and download MySQL Utilities from Launchpad. You can also build and install it from the source code you’ve downloaded using typical Python install steps (python ./setup.py install).

https://launchpad.net/mysql-utilities

What's the link to download these utilities?

MySQL Utilities is part of MySQL Workbench. You can download MySQL Workbench from the following link.

http://www.mysql.com/downloads/workbench/

Locking

Do the utilities lock tables while running?

Yes, but only for situations that require locks. The mysqldbexport utility also allows you to specify what type of lock to use:

no-locks = do not use any table locks

lock-all = use table locks but no transaction and no consistent read

snaphot (default) = consistent read using a single transaction.

Are there any utilities that can show DB locks (like which query is blocking which one)?

No, not currently but that is an excellent suggestion!

mysqldbcompare

How fast is mysqldbcompare? Say a table with 10 million rows?

It is difficult to predict a precise estimate of run time based on number of rows. However, it is generally such that the more rows there are the longer the utility will run. The mysqldbcompare utility is used to produce a difference of two databases. It creates a difference between objects of the same name for either object definitions, data, or both. When comparing object definitions, the performance is very fast because there isn’t a lot of processing involved. When comparing data, the utility uses an algorithm to create checksums for each row in the table. During this phase, the tables are locked. Once that stage is done, the tables are unlocked and the algorithm begins to compact the checksums into chunks, which are later compared between the servers. If the checksums differ, the chunks are expanded and the differences calculated. Thus, for tables containing millions of rows the utility will take some time to complete. The best time to run this utility is during low usage periods such as times reserved for upgrades, backups, and similar operations.

How will running mysqldbcompare effect a production database?

If generating a difference for data, the utility will lock the tables long enough to calculate a checksum for each row. Depending on the number of rows this could be for a long time and in those cases you should run mysqldbcompare during low usage periods. The utility will use a consistent read to lock InnoDB tables but will issue table locks for non-InnoDB tables.

Will mysqldbcompare cause table locking on MyISAM table?

Yes. A table lock is issued during checksum creation.

What is the load going to be on the servers when mysqldbcompare runs?

The load on the server itself is minimal. There is moderate CPU usage during checksum creation but nothing that should cause a problem. The longest period of activity is when the table scans are executed for creating a checksum for each row.

mysqldbexport

Is mysqldbexport similar to mysqldump?

Yes, the mysqldbexport is designed to export data in a row-by-row or logical fashion. However, you can export data in CSV, TAB, Vertical formats as well as SQL statements using CREATE TABLE, INSERT, etc. making mysqldbexport more versatile than mysqldump. You would use mysqldbexport in situations where you need special machine or human readable output for operations like transforming the data or examining the structures in more detail – especially if you need a format other than SQL statements.

Replication Utilities

Are the high availability features available for version 5.5 or 5.6?

The general replication utilities such as mysqlrplcheck and mysqlreplicate will work with servers version 5.0 and later. The newest high availability feature, failover, in mysqlrpladmin and mysqlfailover work only for servers that support global transaction identifiers (GTIDs) which were added in version 5.6.5.

You can discover more about GTIDs from the following blog by Luis Soares.

http://d2-systems.blogspot.co.uk/2012/04/global-transaction-identifiers-are-in.html

Where do I get more info about mysqlrpladmin?

The online MySQL Workbench Manual has information about each utility. You can also use the --help option to show all options and their descriptions.

http://dev.mysql.com/doc/workbench/en/mysql-utilities.html

How can I use the utilities to test replication on a single host?

You can use mysqlserverclone to clone an existing, running instance of MySQL or clone from an installation (basedir), then mysqlreplicate to create the replication topology.

Is the replication failover feature only for version 5.6?

Yes. It requires support for global transaction identifiers, which were added in version 5.6.5. A developer milestone release of 5.6 is available for download.

http://dev.mysql.com/downloads/mysql/#downloads

(Select the Development Releases tab)

What features of mysqlrpladmin will work on version 5.5?

All of the features except slave election and failover.

Do you need to create a replication user on the slave site other than the master?

The mysqlreplicate utility provides an option to use a specific user on the master for replication or it will create a user by default. You can also request that a new user be created during the operation.

MySQL Utilities and Global Transaction Identifiers

Chuck Bell — Tue, 10 Apr 2012 15:40:00 +0000

The new MySQL 5.6 Development Milestone Release (DMR) includes many new enhancements. One of the most impressive is the use of Global Transaction Identifiers (GTIDs) for replication. With GTIDs enabled, administrators no longer need to keep track of binary log files and positions. In a nutshell, GTIDs simplify the setup and maintenance of replication.

MySQL Utilities has taken this a step further by providing two new utilities that automate two of the most complex replication administration tasks - switchover and failover. Switchover is changing the role of an active, healthy master to one of its slaves whereas failover is the act of promoting a candidate slave to become the new master. Clearly, switchover is an elective operation and failover is performed when there are issues with the master.

The GTID utilities are included in release-1.0.5 of MySQL Utilities. They are included as a plugin for MySQL Workbench or via source download from launchpad (see below). The new GTID utilities are included in Workbench version 5.2.39.

Automatic Failover Utility
The most impressive utility is mysqlfailover, It is an interactive tool used to report replication health, report GTIDs in use, and perform automatic failover. Yes, that’s right - you can setup mysqlfailover to automatically failover to one of a specific set of slaves whenever the master goes offline. It is designed to work with the MySQL 5.6.5 and later versions of the server.

As you can see in the screenshot, a list is presented including the host, port, role, state, and replication health for each server in the topology. The utility connects to a single master and its slaves. When used in multiple tier environments, users can run an instance for each master. The utility provides the ability to run a failover check and report health at specific intervals in seconds from five seconds and up

To start the utility, users can specify a list of slaves or provide a default user and password to be used in discovering the slaves connected to the master. Discovery of slaves requires the slaves to report the correct host and port when connecting to the master. Along with the list of slaves, the user can specify a list of servers to be used as candidates for selecting a new master when a failover event is detected.

Finally, the user can control how failover occurs with the failover mode. The auto mode tells the utility to failover to the list of candidates first and if none are viable, search the list of slaves for a candidate. The elect mode limits election to the candidate slave list and if none are viable, failover does not occur. The fail mode tells the utility to not perform failover and instead stop execution.

Along with these options are four extension points permitting users to interact with the utility during failover. These extension points permit users to specify a script to run at each of the following events.

exec-fail-check - execute a script to determine if failover is needed. This replaces the default downed master detection and allows users to perform application-specific detection for failover.
exec-before - execute a script before failover is performed. This can be used to tell the application to cease write attempts while a new master is setup.
exec-after - execute a script immediately after failover to a new master. This permits users to inform the application that the new master is ready.
exec-post-fail - execute a script after failover is complete and all slaves have been attached to the new master. This can be used to inform applications that use read-level scale out that it is safe to resume reads from the slaves.

The combination of options to control failover, the option to perform automatic failover, and the ability to inform applications of the failover event are powerful features that enable unattended automatic failover for critical replication-based applications.

Replication Administration Utility
The other utility, mysqlrpladmin, is used to perform switchover and failover operations and more on-demand permitting administrators to execute these tasks with a single command. You can use the command to perform one of the following commands.

elect - This command is available to only those servers supporting global transaction identifiers (GTIDs), perform best slave election and report best slave to use in the event a switchover or failover is required. Best slave election is simply the first slave to meet the prerequisites.
failover - This command is available to only those servers supporting GTIDs. Conduct failover to the best slave. The command will test each candidate slave listed for the prerequisites. Once a candidate slave is elected, it is made a slave of each of the other slaves thereby collecting any transactions executed on other slaves but not the candidate. In this way, the candidate becomes the most up-to-date slave.
gtid - This command is available to only those servers supporting GTIDs. It displays the contents of the GTID variables used to report GTIDs in replication. The command also displays universally unique identifiers (UUIDs) for all servers.
health - Display the replication health of the topology.
reset - Execute the STOP SLAVE and RESET SLAVE commands on all slaves.
start - Execute the START SLAVE command on all slaves.
stop - Execute the STOP SLAVE command on all slaves.
switchover - Perform slave promotion to a specified candidate slave as designated by the --new-master option. This command is available for both gtid-enabled servers and non-gtid-enabled scenarios.

These two utilities raise the bar for replication ease of use making the administrator’s job easier.

Workbench Scripts

Keith Larson — Fri, 23 Sep 2011 21:45:24 +0000

A was checking out the new Workbench today after I saw this blog post http://wb.mysql.com/?p=1169

It all worked great and very easy. Nice clean code that helps out the PHP Developer.
example:
$host="localhost";
$port=3306;
$socket="";
$user="";
$password="";
$dbname="";

$con = new mysqli($host, $user, $password, $dbname, $port, $socket)
    or die ('Could not connect to the database server' . mysqli_connect_error());

//$con->close();

$query = "SELECT * FROM exampledb";

if ($stmt = $con->prepare($query)) {
    $stmt->execute();
    $stmt->bind_result($field1, $field2);
    while ($stmt->fetch()) {
        //printf("%s, %s\n", $field1, $field2);
    }
    $stmt->close();
}

While this is a simple example it is a fantastic way for new developers to get started and learn how things are done.

A DBA can easily write a complex query and hand over PHP code to the developer. Nice work!

The ability to then write your own plugins really opens it up for some advanced developers.

This is a step in the right direction and supports working together between DBA and developer.

Tech Writer Wanted for MySQL Workbench & Connectors

Stefan Hinz — Wed, 25 May 2011 08:12:58 +0000

The MySQL Documentation Team is looking for a senior technical writer. Main areas to cover are MySQL Workbench and MySQL Connectors. The position is for EMEA.

Candidates should be prepared to work intensively with our developers and support organization when writing documentation. Being a distributed team, we meet mostly on IRC and coordinate our work through email and versioning systems such as Subversion. The base format we're using is DocBook XML, and we're not just writing but also processing and publishing all our documentation ourselves.

This means you should be ready to use "non-wysiwyg" text editors, have a clue about XML and XSL, and be prepared to communicate over the Internet most of the time. Naturally, you should have some experience documenting database software. We're striving for high quality (good and understandable writing, accuracy, completeness, attention to details, timeliness) — people are actually reading the documentation we provide; our online viewable formats get millions of page views every month.

If you think you qualify, drop me a mail, and let me know what time would be best to get together on the phone.
