In turn, MaxScale distributes these queries according to their purpose, transactional queries are sent to MariaDB Servers for OLTP workloads, and analytical queries are sent to MariaDB ColumnStore for OLAP operations.

It’s made by the original developers of MySQL and guaranteed to stay open source.

If there are no errors, MaxScale-1 is now running as a replication slave to Server-1. You can verify that replication is working using a SHOW SLAVE STATUS statement. A retail store wants to amplify sales by providing a personalized shopping experience. When a customer checks out at a cash register or online, the customer is presented promotions tailored to the customer’s interests. These offers may also be integrated across channels, available when the known customer visits the website, shops by mobile phone app, or be included in the next personalized email sent to the customer.

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. In HTAP deployments the only queries issued to MariaDB ColumnStore are those specific to OLAP workloads, which does not include writes. In order to update ColumnStore with new data written to the MariaDB Servers, configure MaxScale on the back-end to stream writes to ColumnStore.

The first steps cover server installation and deployment; the next cover configuration for Replication, Data Streaming, and Application Traffic, and lastly Testing with OLTP and OLAP queries and with DML statements. A chain of convenience stores maintains an IoT network in which each store records data on its milk inventory levels and sensor data such as refrigerator temperature. The central office continuously monitors inventory levels to trigger replenishment on an as-needed basis.

The MariaDB MaxScale server configuration above designates queries on the table as analytical queries and routes them to the MariaDB ColumnStore User Modules rather than the MariaDB Servers. Once you’ve installed and configured the MaxScale and the CDC Data Adapter, you can run checks to verify that it is properly configured mariadb development 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. 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, .

When you start streaming data, the mxs_adapter utility begins printing logging messages to stdout. As you add data to the MariaDB Servers, you can check this output to see binary events streaming over to ColumnStore. Lastly, using the maxctrl utility, create a user for the Avro Router to capture data changes. This user handles streaming data MaxScale retrieves from the MariaDB Servers to ColumnStore. Our sample deployment calls for five servers to run MariaDB ColumnStore to handle OLAP workloads. Two of these servers operate as User Module servers, named UM-1 and UM-2, and receive application traffic from MaxScale.

For customers, the advantage is that there’s now only one product to buy. You can apportion nodes in the cluster to transactions and analytics as you wish; in fact, if you wanted to go pure row store or pure columnar, you could do that as well. As MariaDB prices per node, not by the storage engine, customers do not have to pay for two data stores if they only want one. In a blog post announcing the release, the company outlined some technical details. The product contains two separate instances of MariaDB server — one for transactional, one for analytical work. Data is stored on the transactional side, with changes and updates synchronized to the analytical side, which uses MariaDB’s ColumnStore engineto handle data for real-time analysis.

The new release merges them into the core database engine, enabling complex queries across transactional data. 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. 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. That was when we first started to bring together transactions and analytics. Platform X4 fully integrates them to create a seamless experience for developers and DBAs, and you can expect to see more with each subsequent release as we build on this notion of smart transactions and insightful experiences.

Sample Platform X3 implementation for Transactional and Analytical Workloads

Our sample deployment calls for two servers to run MariaDB MaxScale. The first server, named MaxScale-1, handles data streaming from the MariaDB Servers to the MariaDB ColumnStore servers. The second, named MaxScale-2, selectively proxies application traffic to the respective servers for OLTP and OLAP workloads.

High Availability & Performance Tuning

MariaDB Platform X3 is tailored to a world where businesses need to monetize more of their data in practical ways and in real time. The Query Router acts as the brains, either by directing queries based on schema, table, regular expressions (i.e. syntax) or provides “hints” based on preset rules. We believe that in the future, it would make sense to automate this further as another example of how machine learning could optimize databases.

  • Perform the following operations on each slave server, (that is, Server-2 through Server-4).
  • Data is stored on the transactional side, with changes and updates synchronized to the analytical side, which uses MariaDB’s ColumnStore engineto handle data for real-time analysis.
  • They will drive and support applications during the mass adoption of automation technologies and support them in their journey to an increasingly automated state.
  • With its new release, MariaDB is bringing its separate analytic and transaction offerings into a single platform.
  • The first steps cover server installation and deployment; the next cover configuration for Replication, Data Streaming, and Application Traffic, and lastly Testing with OLTP and OLAP queries and with DML statements.

Additionally, the application generates reports analyzing transaction activities. These reports are adapted for categories of customers or for types of transactions (cash deposits, checks, ATM deposits, in-branch deposits, transfers, withdrawals). These reports can be run by the customers on their individual accounts or by the bank’s back office on all customer activities. Smaller diagram of query routing and data streaming on Platform X3.

We have also created the bank database and tables in MariaDB ColumnStore. The MaxScale CDC Streaming Data Adapter allows you to stream binary log events from MariaDB Servers to MariaDB ColumnStore clusters. In order to use it, install the ColumnStore Bulk Write SDK and the MaxScale CDC Adapter packages on a dedicated host or on any MaxScale server that you want to use for data streaming, (MaxScale-1 in our sample deployment). 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.
