This is a presentation held at eLiberatica 2009. http://www.eliberatica.ro/2009/ One of the biggest events of its kind in Eastern Europe, eLiberatica brings community leaders from around the world to discuss about the hottest topics in FLOSS movement, demonstrating the advantages of adopting, using and developing Open Source and Free Software solutions. The eLiberatica organizational committee together with our speakers and guests, have graciously allowed media representatives and all attendees to photograph, videotape and otherwise record their sessions, on the condition that the photos, videos and recordings are licensed under the Creative Commons Share-Alike 3.0 License.

To keep the MySQL talent together
To ensure that there always exists a free version of
MySQL

of MySQL
Work with Drizzle to share knowhow and code

3. Why the Open Database Alliance was created
‣ To enlarge the open marketplace for MariaDB/MySQL
‣ To gather together all companies doing business on
MariaDB and MySQL
‣ To provide a one-stop-shop for MariaDB/MySQL
customers (Everyone in the Alliance can sell others
services and products)
‣ More flexible services for the customer than one big
company can provide
‣ Later
we would like to enlarge the Alliance to cover all
open source databases

4. New Features in MariaDB 1.5
‣ MariaDB 5.1 is kept up to date with MySQL 5.1 (pulls done monthly or
when there is a new MySQL build)
‣ pool-of-threads (backport from 6.0) with new option –extra-port=#
‣ This allows an admin to login and resolve lock issues with threads in the
pool and also allow different schedulers for different connections
‣ Binaries with up to date versions of Maria, PBXT and XtraDB
‣ We have fixed a lot of compiler warnings and errors found by valgrind
‣ Faster complex queries (that uses disk based temporary tables)
‣ Speed improvements; sql_bench benchmarks shows 10 % speedup for
some common queries that returns lots of simple character data
‣ Generated (virtual) columns (Patch to be pushed)
‣ Detector if mutex are wrongly used

5. New features to be added to MariaDB 1.5
The new Federated storage engine.
Proven and stable community patches we feel offer important
performance or feature enhancements. Percona and ourdelta
patches exemplify this work.
microslow_innodb.patch
microsec_process.patch
Memory tables with efficient VARCHAR/BLOB support
Some safe cleanups of the code.
Others ?
