In this blog post, we take a close look at MariaDB ColumnStore data redundancy, a new feature of MariaDB AX. This feature enables you to have highly available storage and automated PM failover when using local disk storage.
Recently, we had a discussion about a hypothetical feature, "START TRANSACTION ON ERROR ROLLBACK", that our users would find very useful. It would allow sending several commands to the server in one batch (a single network packet), and let the server handle the errors. This would combine efficient network use, and atomic execution. It turns out that it is already possible to do this with MariaDB, albeit with a slightly different syntax.
In this blog post, we show how to connect Tableau to MariaDB TX or MariaDB AX and how to create advanced visualizations in Tableau using data in MariaDB.
Learn how Billy Mobile deployed MariaDB ColumnStore for fast, interactive analysis of big data that easily integrates with Tableau for data visualization.
There are many great unique features of MariaDB ColumnStore, one of which is the speed in which you can get data from CSV files into MariaDB ColumnStore using the tool ‘cpimport’. But what if your data is in another format? Or you wish to stream data into MariaDB ColumnStore from another application? This is where MariaDB ColumnStore’s new write API comes into play.
The MariaDB project is pleased to announce the immediate availability of MariaDB Connector/C 2.3.4. See the release notes and changelog for details.
With MariaDB MaxScale 2.2 (currently in beta) the monitor for MariaDB instances can detect a Binlog server setup and SQL statements can be properly routed among Master and Slave servers.
The “identity” of the binlog server layer from the slave server’s point of view is something that could be modified in order to provide all slaves such common parameters for all MariaDB MaxScale server they could replicate from.
We have learned that the MariaDB ColumnStore prerequisites and install can be complex for multi-node installs so we decided it would help our users to develop a tool to validate for install readiness. This tool will validate the setup whether installing on a single server or a multi-server system. It is called MariaDB ColumnStore Cluster Test Tool. It is part of the MariaDB ColumnStore package and can be run from the installing server once the MariaDB ColumnStore package has been installed.
The MariaDB project is pleased to announce the immediate availability of MariaDB Server 10.2.11. See the release notes and changelog for details.
