At a technical level, purchasing of a milk carton or container triggers an OLTP query, and inventory reporting is an OLAP query. OLTP data is used for logging, and analysis of OLAP data drives understanding of product losses, replenishment patterns, and equipment failures. As companies continue to grapple with changing customer demands, technology has played a critical role, and we’ve been fortunate to partner with and serve people, companies, and government institutions in Germany and around the world to help them adapt. The Google Cloud region in Berlin-Brandenburg and the expansion of our Google Cloud region in Hanau will help our customers — such as BMG, Delivery Hero, and Deutsche Bank — adapt to new requirements, new opportunities and new ways of working.
In MariaDB Replication, one server operates as the master receiving all writes from the application and replicating changes to the cluster. The other servers operate as slaves, receiving reads from the application and only accepting writes from the master server. Additionally, the application generates reports analyzing transaction activities. These reports are adapted for categories of customers (business, student, regular checking, savings) or for types of transactions (cash deposits, checks, ATM deposits, in-branch deposits, transfers, withdrawals).

It also prevents application users from seeing and querying historical data. MariaDB Platform X3 brings together MariaDB TX and MariaDB AX in one platform that can uniquely scale out transactions or analytics to support business growth goals. With a single unified product, MariaDB Platform X3 reduces complexity and increases operational and analytical efficiency, giving application users full visibility and analytical access to historical data. MariaDB Platform X3 is tailored to a world where businesses need to monetize more of their data in practical ways and in real time. MariaDB ColumnStore extends MariaDB Server with distributed storage and massively parallel processing to support scalable, high-performance analytics.
With the CDC Data Adapter installed you can configure it to stream data to MariaDB ColumnStore. This is done by copying the Columnstore.xml configuration file from one of the ColumnStore nodes to the MaxScale-1 server, where the CDC Data Adapter can use it. If there are no errors, MaxScale-1 is now running as a replication slave to Server-1. At a technical level, when an OLTP query is performed to process the customer’s purchase, the customer’s past and current purchase history is analyzed with an OLAP query to provide promotions tailored to the customer’s buying history. On the back-end, changes made to the MariaDB Servers are sent through MaxScale streaming data adapters to ColumnStore, ensuring that ColumnStore remains up-to-date.
New MariaDB Platform Launches in the Cloud
Jupyter notebooks success is that it excels in a form of programming called “literate programming”. Literate programming allows users to formulate and describe their thoughts with prose, supplemented by mathematical equations, as they prepare to write code blocks. Since MaxScale routes the query as an analytical operation, the version_comment system variable indicates a ColumnStore server. These are the same command-line options as you would use to connect to a MariaDB Server, but instead of an individual server, you connect to MaxScale, which sends the queries to the Servers or to one of the ColumnStore UM’s.
For production environments, try Xpand in SkySQL, a fully managed cloud database service that offers both single node and multi-node deployments. With https://www.globalcloudteam.com/, an organization may use a single database both for conventional customer-facing workloads (transactional, or OLTP) and internal business-intelligence workloads (analytical, or OLAP). The same data is available for either kind of work and is kept automatically in sync between the two sides. The MariaDB MaxScale server configuration above designates queries on tables other than bank.loan as transactional and routes them to the MariaDB Servers rather than ColumnStore. At this point, we have created the bank database and tables, and have loaded the data into the MariaDB Servers, (though we only wrote to Server-1, as the master server it has replicated the data out to the slaves). Issue a CHANGE MASTER TO statement to use the master MariaDB Server host (that is, the IP address to Server-1) and the port for client connections, (which defaults to 3306).
Expanding our infrastructure around the world
Berlin, Frankfurt, Hamburg and Munich have long been our home, and we continue to invest in the growth of the local economy. You can reach out to us on Zulip, our mailing lists, as well as on our public issue tracker. These tools are currently available and labeled as “Development (non-production)”. Software designated as “Development (non-production)” or “Technical Preview” should not be used for production workloads. In this session Max Mether, VP of Product Management at MariaDB, provides an introduction to MariaDB Platform X3 and the new features in MariaDB Server 10.3 and MariaDB MaxScale 2.3.
In order for MariaDB to be easier to use for DBAs and skilled database engineers from other products, we wanted to add as much compatibility as possible. It is built upon the values of performance, stability, and openness, and MariaDB Foundation ensures contributions will be accepted on technical merit. Recent new functionality includes advanced clustering with Galera Cluster 4, compatibility features with Oracle Database and Temporal Data Tables, allowing one to query the data as it stood at any point in the past. In streaming data from MariaDB Server to ColumnStore for analysis, MaxScale requires that the Servers format the binary log events by each row modified by a statement, rather than by operation. So, when deploying a cluster for HTAP, ensure that the binlog_format system variable on the MariaDB Servers is always set to the ROW value.
MariaDB ColumnStore: Distributed, columnar storage and processing for scalable analytics
In addition to this, we have added a multitude of features to help speed up schema operations (like instant ADD COLUMN) and other optimizations and compatibility features. The ADD COLUMN feature is another example of our collaboration with customers and partners including Alibaba, Tencent and ServiceNow, and is just the beginning of making heavy DDL operations more usable. MariaDB Server is one of the most popular open source relational databases. It’s made by the original developers of MySQL and guaranteed to stay open source.
Since 2017, Google has matched 100% of our global, annual electricity use with renewable energy. Last year, we set out to run our business on carbon-free energy everywhere and at all times by 2030, enabling us to offer cloud customers one of the cleanest mariadb development clouds in the industry, while helping Europe achieve its ambitious climate goals. As the demand for MariaDB Server has increased in larger enterprises we have also seen a need for features that are readily available in proprietary databases.
MariaDB Platform X3 combines transaction processing and analytics
In this scenario, queries listing account information and general transaction activities are OLTP operations. Reports analyzing transaction activities run by the customer for individual accounts or by the bank on all customers are OLAP operations. For OLAP operations, our sample deployment uses five MariaDB ColumnStore nodes, two of which are configured as User Modules (UM’s) and three as Performance Modules (PM’s).
- Factors like read/write mix, OLTP queries versus analytics queries, high availability requirements and much more will drive different topologies for production clusters.
- So, when deploying a cluster for HTAP, ensure that the binlog_format system variable on the MariaDB Servers is always set to the ROW value.
- ColumnStore can optionally use object storage services in public or private clouds to lower costs and store an unlimited amount of data.
- In this session Max Mether, VP of Product Management at MariaDB, provides an introduction to MariaDB Platform X3 and the new features in MariaDB Server 10.3 and MariaDB MaxScale 2.3.
- MariaDB Community Server now includes ColumnStore for real-time analytics at scale.
- MariaDB Platform X3 is tailored to a world where businesses need to monetize more of their data in practical ways and in real time.
MariaDB Platform is an enterprise open source database for transactional, analytical and hybrid transactional/analytical workloads. It uses row storage for transactions and columnar storage for analytics, but unlike proprietary databases from Oracle and Microsoft, the columnar storage in MariaDB Platform is distributed to support analytics at scale. MariaDB Platform is an enterprise open source database for hybrid transactional/analytical processing at any scale, with row storage for transactions and columnar storage for analytics. It’s built for businesses whose customers demand more information and deeper insight.
Platform X3 Scaleout
Today, we’re excited to announce that ENGIE Deutschland has been selected as Google’s carbon-free energy supplier in Germany. Under the terms of the agreement, ENGIE will assemble and develop, on Google’s behalf, a 140 megawatt (MW) carbon-free energy portfolio in Germany that has the ability to flex and grow with us as our needs change. This includes a new 39MW solar Photovoltaic system, and 22 wind parks in five federal states that will see their lives extended so they continue to produce electricity instead of being dismantled.
