These are shown at the left of our sample deployment diagram, in orange. To manage network communication between the application and our deployment and between the database servers we use two MaxScale servers, one to handle the back-end data streaming and the other to handle selective query proxying from your application. In scaling for the network load, you can add MaxScale servers to the first to handle a larger database write load or to the second to manage a greater number of queries from your application.

• OLTP data is used for logging, and analysis of OLAP data drives understanding of product losses, replenishment patterns, and equipment failures.
• To help customers take their cloud strategies to the next level, MariaDB has launched a Managed Service for public and hybrid cloud deployments.
• The second, named MaxScale-2, selectively proxies application traffic to the respective servers for OLTP and OLAP workloads.
• You can identify which server cluster the query executes on using the version_comment system variable.
• Additionally, ensure that SELinux has a policy allowing these connections or that it is running in permissive mode.
• The main challenge with implementing both transactional and analytical workloads is that they require different programming models and different types of data access.
• There are two API’s, one that is text-based and this is the original MariaDB API. In this API all data is sent and received as text.

This path allows us to adapt quickly to an ever-changing landscape where new innovations are being created at a constantly accelerated pace. This is our greatest release yet and, with this release, we want to put our stake in the Enterprise database category. Sample Platform X3 is a MariaDB database platform designed to support both transactional and analytical workloads.

Platform X3 Scaleout

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. 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. Columnar Storage – Column oriented data stores are more suitable for analytical workloads because the data format lends itself to faster query processing — scans, aggregation et cetera. 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.

Xpand maintains two replicas of all data using a rebalancer process that runs in the background. MariaDB Xpand uses a component called the “rebalancer” to automatically and transparently distribute data across the available Xpand nodes. Easy to maintain – Database Administrators love the fact that MariaDB Platform X3 does not add complexity to the analytical and exploratory environment. When you're ready to install MariaDB Platform X3, go to Downloads and select Platform X3. If you use an RPM or APT based distribution of Linux, you can configure your server repositories to install it through the package manager.

Platform X3 Query Routing and Data Streaming

To explain further above, the Xpand splits a number of slices for each table that is built using Xpand. Each slice is stored on a primary node and then replicated to one or more other nodes to ensure fault tolerance. MariaDB Platform is priced at a flat per-node cost, regardless of whether nodes are OLTP or OLAP.

Although that may be enticing, it requires special licensing and large fees in order for you to leverage this product. If it serves a purpose for your enterprise application, then this MariaDB Xpand might be worth a try. This is very different from other systems, which routinely move large amounts of data to the node that is processing the query, then eliminate all the data that doesn’t fit the query . By only moving qualified data across the network to the requesting node, Xpand significantly reduces the network traffic bottleneck. Parallelization of queries, which are distributed to the node with the relevant data. Results are created as close to the data as possible, then routed back to the requesting node for consolidation and returned to the client.

New to MariaDB Server?

“One database, any workload” is how the company is pitchingMariaDB Platform X3. Finally, Platform X3 provides support for primary-secondary indexing, which can be used to improve the performance of both transactional and analytical workloads. Platform X3 also provides distributed query optimization, which can reduce the amount of data that needs to be transferred between nodes and improve the performance of analytical queries. 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). We have also created the bank database and tables in MariaDB ColumnStore.

While purchases require transactions, useful information (e.g., this product will be sold-out within hours) requires analytics. Consequently, these applications need access to more historical data and more powerful analytics – things transactional databases cannot provide, at least not at scale. MariaDB Corporation, developers of the MariaDB open-source fork of MySQL, have announced a new open source database—a fusion of two of its existing products—that processes both transactional and analytical workloads on the same dataset. Under the hood, MariaDB Platform executes transactions and analytics on separate database instances. The first server, named MaxScale-1, handles data streaming from the MariaDB Servers to the MariaDB ColumnStore servers.

MariaDB Platform X3 combines transaction processing and analytics

It holds the result of the mean, variance and standard deviation calculation of the different dog breeds. Employees data is used to demonstrate the advanced statistical functions such as co-variance and correlation. 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.

MyRocks comes from a collaboration with Facebook where the storage engine is built on top of RocksDB – an open source project mainly maintained by Facebook. The MyRocks storage engine is built using a log-structured merge tree architecture and is well adapted to high write workloads. MyRocks also has a very high compression ratio and is built https://www.globalcloudteam.com/ to optimize the lifetime of SSD disks. Xpand simplifies efficiency and expandability in a very convenient fashion. The most appealing aspect of this product is that you can use MariaDB’s standard SQL functions as well. It can be embedded through your existing MariaDB environment, which can take advantage of its features and scalability.

First, workload-based isolation removes resource contention between transactions and analytics. Second, independent workload scaling allows transactional and analytical workloads to be scaled independently of each mariadb development other. Third, the hardware for database instances running transactions can be optimized for transactions (e.g., SSDs) while the ones running analytics can be optimized for analytics (e.g., many core processors).

Queries are parallelized and distributed across the cluster to the relevant data. New nodes are automatically recognized and incorporated into the cluster. Workloads and data are automatically balanced across all nodes in the cluster.

In B2B, SaaS in particular, customers are data-driven organizations themselves. Beyond the core service provided, they need more powerful, self-service analytics. They need to be able to uncover actionable insight like every other business, but they rarely have direct access to the underlying data. Once you've installed and configured the MaxScale and the CDC Data Adapter, you can run checks to verify that it is properly configured and able to communicate and stream data from the MariaDB Servers to the MariaDB ColumnStore cluster. Using the mxs_adapter utility, you can connect to MaxScale and test data streaming.
