This video will show you how to install MaxScale on Centos 8 Stream and then enable the GUI. MariaDB MaxScale is a database proxy that extends the high availability, scalability, and security capabilities of a MariaDB server while simplifying application development by decoupling applications from the underlying database infrastructure. 0:00 Start 0:32 Installing the MaxScale repository 1:36 Se...

GTID (Global Transaction ID) is a powerful tool that greatly simplifies replication management in MariaDB. Using GTID allows you to accurately track each transaction in a cluster of servers, which makes the synchronization process more reliable and convenient. In this video, we will cover the basic principles of GTID, the benefits of using it, and also walk through how to configure and effectiv...

This video will show you how to set up synchronous replication in MariaDB without much effort. In normal asynchronous replication, replicas query the primary server's binary log for events when the replicas are ready. The primary server does not wait for the replica to acknowledge that the event was received. With fully synchronous replication, all replicas must respond that they have received ...

Replication in PostgreSQL plays a vital role in ensuring high availability and data redundancy in your database. In the event that the primary server becomes unavailable, switching to a backup server can help maintain uninterrupted access to your data. This video describes the step-by-step process of manual switching in PostgreSQL. By following the guide, you can smoothly transition from the ma...

PostgreSQL streaming replication is a process that replicates data from a primary PostgreSQL database to one or more standby databases in real time, ensuring that those standby databases accurately reflect the primary database. This replication method provides high availability and redundancy by synchronizing backup servers with the primary server. Replication slots provide an automated way to ...

pg_basebackup is a simple but powerful utility provided by PostgreSQL to create consistent online backups at the filesystem level. Backups created with this command contain the actual database files, so you do not need to restore such backups. You can simply unzip the backup files and copy them to the database data directory. In this video, we'll walk through the process of creating backups usi...

Tablespaces are designed to distribute Postgres clusters across multiple storage devices. Create Tablespace creates a symbolic link in the pg_tblspc directory in the cluster data directory pointing to the newly created tablespace directory. Unfortunately, there is no command to move tablespaces to different directories. Therefore, today we will look at how you can very easily and quickly move t...

By default, the cassandra DBMS does not have a normal mechanism that could stop, start or restart the database on a node. To stop the database we simply need to find the cassandra process and use the kill command to kill this process. That’s why in this video we will create a script that we will then add to systemd, with the help of which it will be convenient to start, stop and restart the dat...

This video will show you how to safely change the Java garbage collector from CMS to G1 GC (Garbage Collection) is a high-level abstraction that relieves developers of the need to worry about freeing managed memory. During the garbage collection process, the runtime will examine objects on the heap to determine whether they are still reachable (i.e., rooted) by the application. 0:00 Start 0:11 ...

This video will discuss in detail how you can safely upgrade the Cassandra DBMS from version 3 to version 4 on Centos 8. In version 4 there were a lot of positive updates and support for Java 11 version appeared. Also added is the ability to enable auditing and much more. 0:00 Start 0:15 Checking which version of the Cassandra DBMS is currently installed 1:19 Checking which version of Java is c...
