If you’re still thinking about whether or not you should be attending the Percona Live MySQL Conference & Expo that starts on Monday 31st of March, here are 9 reasons (we are Severalnines after all) on why we’ll be there. May these help you positively in your decision making ;-)

1. The 2014 edition showcases the most promising program yet

Sounds like a cliché-reason to be listed here, but this year’s program is in fact quite diversified in its …

Percona Server 5.6.11-60.3 introduces a new “log archiving” feature. Percona XtraBackup 2.1.5 supports “apply archived logs.” What does it mean and how it can be used?

Percona products propose three kinds of incremental backups. The first is full scan of data files and comparison the data with backup data to find some delta. This approach provides a history of changes and saves disk space by storing only data deltas. But the disadvantage is a full-data file scan that adds load to the disk subsystem. The second kind of incremental backup avoids extra disk load during data file scans.

The idea is in reading only changed data pages. The information about what specific pages were changed is provided by the server itself which …

Hadoop is an increasingly popular means of analyzing transaction data from single MySQL or multiple MySQL servers. Up until now mechanisms for moving data between MySQL and Hadoop have been rather limited. The new Continuent Tungsten Replicator 3.0 provides enterprise-quality replication from MySQL to Hadoop. Tungsten Replicator 3.0 is 100% open source, released under a GPL V2 license, and

Joro wrote recently about MySQL 5.6.17‘s new support for AES-256 encryption, and it’s a great improvement for people need to encrypt their data at rest.  The new session block_encryption_mode variable controls what variant of AES is used, and for backwards compatibility, the default behavior remains 128-bit key length with ECB block cipher mode.  If you’re happy with that level of encryption, nothing changes – your existing code will work the same on 5.6.17 as it has on earlier versions (note that users of statement-based replication will experience new warnings).  There are good examples of how to use …

Today new version of JSON UDF functions: 0.3.1 was released. This is development release which contains new functionality. You can download functions from the MySQL Labs website.

What is new?

Default value for compile option `WITH_PCRE` now is `bundled` independently from the
platform (Bug #71265/18081332 Library name mismatch for PCRE on Ubuntu)

New values, passed to functions `JSON_APPEND`, `JSON_REPLACE`, `JSON_SET` as numbers, empty strings or `NULL`s are converted to JSON objects. Objects, passed as strings are not converted: you are still responsible to put quotes around string values. Also these functions check if element which needs to be inserted is valid JSON value. (Bug #70394/17491708 MySQL JSON UDFs: …

The MySQL Windows Experience Team is proud to announce the release of MySQL for Excel version 1.2.1.

MySQL for Excel 1.2.1 is a maintenance release for 1.2.x containing a handful of bug fixes and the following minor features:

• When MySQL Workbench is not installed, MySQL connections are now automatically created for discovered MySQL services. If MySQL Workbench is later installed, these connections are not migrated over to MySQL Workbench as MySQL Workbench also creates connections for discovered MySQL services.
