Introducing MariaDB Platform X3 and the Rise of Hybrid Everything

MariaDB Platform scales on commodity hardware, on premises or in the cloud, eliminating the need to spend budget on proprietary data warehouses and appliances. Start by using Xpand for just a single table and expand the usage as your needs grow beyond what a single node can handle. Increase the use of distributed SQL as your enterprise needs grow beyond replication or clustering. When data or query volumes increase to the point of degrading performance, you can use Xpand to distribute tables or the entire database for improved throughput and concurrency. Xpand has built-in high-availability and elasticity, so nodes can be added or removed transparently as needed to scale-out. This loose coupling provides MariaDB Platform with multiple benefits.

When the failed node is replaced, the rebalancer redistributes data, restoring MariaDB Xpand to its intended node count.

Deploy MariaDB Servers

Check each server to ensure that there is no firewall blocking these ports. Additionally, ensure that SELinux has a policy allowing these connections or that it is running in permissive mode. 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. Once you’ve started the replication slave process on MaxScale, you can check it using the SHOW SLAVE STATUS statement, just as you would when checking the status of a slave MariaDB Server. Unlike when connecting to MariaDB Servers previously, use port 6603, (which you configured above in the /etc/maxscale.cnf file as the replication listener port).

The central office continuously monitors inventory levels to trigger replenishment on an as-needed basis. The maintenance teams and store also receive real-time alerts if issues arise with the cooling system, speeding repair and reducing product losses. A holistic, whole-picture view of supply levels and status allows the chain to keep costs low and the customer experience consistent.

This allows for more flexible deployments, where the number of nodes in a given deployment can be moved freely between OLTP and OLAP workloads as demand changes. Configure for Application Traffic When your application issues queries to Platform X3 for HTAP operations, it doesn’t connect to either the MariaDB Servers or to the MariaDB ColumnStore User Modules directly. MariaDB Platform introduces a number of aggregate statistical functions used to process complex data sets. Use the username and password for the CDC user created in the previous section. In the MaxScale configuration, we set port 4001 for the listener service. The CDC Data Adapter uses the same ports to stream data from MaxScale-1 to ColumnStore.

  • Temporal data processing through our system versioning feature is one of the more exciting additions in the MariaDB Server 10.3 release.
  • If you use an RPM or APT based distribution of Linux, you can configure your server repositories to install it through the package manager.
  • Now called Xpand, it extends MariaDB Enterprise Server with distributed data and transaction processing, transforming it into a distributed SQL database capable of scaling to millions of transactions per second with a shared-nothing architecture.
  • The Spider storage engine allows you to shard a specific table across multiple nodes.
  • Aligning program data contained in classes or similar is also easier, allowing for better code integration.

In scaling OLTP, you can increases the number of MariaDB Servers, allowing for high availability, replication backups and failover. MariaDB Platform X3 can operate from individual servers, but as your application grows more complicated and your database workload increases, each component can scale out to suit your particular infrastructure needs. If the load on MariaDB Xpand increases, you can scale out by adding new nodes.


The same data is available for either kind of work and is kept automatically in sync between the two sides. Configure for data streaming In HTAP deployments the only queries issued to MariaDB ColumnStore are those specific to OLAP workloads, which does not include writes. Pymsql module is used to connect from the Jupyter notebook to MariaDB. Then establish a database connection providing user credentials and server information. An example of MariaDB Platform support for statistical functions within a Jupyter notebook is presented here.

From your application server use the MariaDB Client to connect to the MaxScale HTAP Service. Then, modify the schema to add a balance column to the table. Create a read user for MaxScale on the master MariaDB Server Server-1 and the ColumnStore User Modules. If there are no errors, MaxScale-1 is now running as a replication slave to Server-1. At a technical level, purchasing of a milk carton or container triggers an OLTP query, and inventory reporting is an OLAP query.

Since MaxScale routes this query as a transactional operation, the version_comment system variable returns MariaDB Server. Here is the configuration file you should have in /etc/maxscale.cnf on MaxScale-2 to achieve the above. You can verify that replication is working using a SHOW SLAVE STATUS statement.

To help with this challenge, Platform X3 provides built-in support for sharding and replication of data, allowing multiple copies of data to be stored in separate nodes and accessed in parallel. This can improve the performance of both transactional and analytical workloads. When these applications only needed to facilitate transactions, a transactional database was sufficient. Today, applications have to do a lot more – customers expect it, and are increasingly demanding it.

Deploy MariaDB ColumnStore Servers

Xpand leverages a shared-nothing architecture; a single node handles each request, and memory and storage are not shared. MariaDB Enterprise Server collects the return data from the Xpand nodes to generate a result-set. I should note that this image is intended for test and development purposes. MariaDB Platform is supported on Docker for production installations, but those installations should be based on laying down many of the individual components into their own containers. The Single Container Image combines MaxScale, a MariaDB Server Master/Slave/Slave setup, MariaDB ColumnStore running a single UM and a single PM, and the necessary CDC components into one Docker image. Data discovery – Enable data engineers, data analysts and data scientists, to have an interactive computing environment that can drive exploration using notebooks (e.g., Jupyter) and structured query language .

To help customers take their cloud strategies to the next level, MariaDB has launched a Managed Service for public and hybrid cloud deployments. The MariaDB Managed Service goes beyond standard database implementation, backup and recovery, and regular upgrades by providing proactive monitoring, migration, schema changes, query optimization, performance tuning and security updates. Unlike cloud vendors that limit technical support to database operations issues, MariaDB Managed Service goes the extra mile to accurately diagnose issues, identify root causes and work with customers to prevent recurrent problems. The Managed Service offers three best practice starter configurations for transactions, analytics (standalone or to complement an existing on-prem transactional implementation) or hybrid transactional/analytical .

You can identify which server cluster the query executes on using the version_comment system variable. 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, . Set the user and password as defined mariadb development for the replication router in /etc/maxscale.cnf above. With each slave MariaDB Server in your deployment, configure it to replicate data from the master server and start the replication process. Perform the following operations on each slave server, (that is, Server-2 through Server-4).
