Mariadb Presentation
THE VALUE OF OPEN SOURCE MICHAEL ”MONTY” WIDENIUS Entrepreneur, MariaDB Hacker, MariaDB CTO MariaDB Corporation AB 2019-09-25 Seoul 11 Reasons Open Source is Better than Closed Source ● Using open standards (no lock in into proprietary standards) ● Resource friendly; OSS software tend to work on old hardware ● Lower cost; Usually 1/10 of closed source software ● No cost for testing the full software ● Better documentation and more troubleshooting resources ● Better support, in many cases directly from the developers ● Better security, auditability (no trap doors and more eye balls) ● Better quality; Developed together with users ● Better customizability; You can also participate in development ● No vendor lock in; More than one vendor can give support ● When using open source, you take charge of your own future Note that using open source does not mean that you have to become a software producer! OPEN SOURCE, THE GOOD AND THE BAD ● Open source is a better way to develop software ● More developers ● More spread ● Better code (in many cases) ● Works good for projects that can freely used by a lot of companies in their production or products. ● It's very hard to create a profitable company developing an open source project. ● Not enough money to pay developers. ● Hard to get money and investors for most projects (except for infrastructure projects like libraries or daemon services). OPEN SOURCE IS NATURAL OR WHY OPEN SOURCE WORKS ● You use open source because it's less expensive (and re-usable) ● You solve your own problems and get free help and development efforts from others while doing it. -

A Closer Look at Mysql Cluster an Architectural Overview - Mariadb White Paper - 08-26-13-001.Docx Page 1
w: www.mariadb.com e: [email protected] MySQL Cluster Internal Architecture Max Mether MariaDB Keywords: MySQL Cluster, MySQL, High Availability, HA, Clustering, Architecture 1 Introduction MySQL Cluster is tightly linked to the MySQL server, yet it is a separate product. Due to its distributed nature, MySQL Cluster has a far more complicated architecture than a standard MySQL database. This presentation and white paper will describe the internal architecture of the MySQL Cluster product and the different mechanisms and process that exists to insure the availability of the cluster. We will also take a close look at the data and message flow that takes place between the nodes in the cluster during different types of operations. 2 MySQL Cluster Features MySQL Cluster can be distinguished from many other clustering products in that it offers five nines availability with a shared-nothing architecture. Most clustering products use a shared-disk architecture. Using a shared- nothing architecture allows the cluster to run on commodity hardware, thus greatly reducing costs compared to shared-disk architecture. Having a shared-nothing architecture does, however, come with a different cost, namely, a more complex way of ensuring high availability and synchronization of the nodes which is mainly seen as increased network traffic. MySQL Cluster also provides ACID transactions with row level locking using the READ-COMMITTED isolation level. MySQL Cluster is, in general, an in-memory database, however non-indexed data can be stored on disk and the disks are also used for checkpointing to ensure durability through system shutdown. MySQL cluster provides unique hash indexes as well as ordered T-tree indexes. -
