MySQL in Amazon (RDS)
March 16, 2021
If you are dealing with data, and you most probably are if you are reading this, one of your biggest fears would be not to be able to retrieve them. In a world where data actually surround us, it is critical to be able to retrieve them fast and with the best consistency.
Thus, it is always a good idea to have high availability settings in place to avoid loosing your data.
However, most of the times, we may wish or we may need to save the database and our data, and be a DBA-hero. Not an easy task, and it may be smoother to just perform a backup-restore. Sadly, this is not always the case.
So, this is what we will be facing in this article, we are going to see what to do when there is a data corruption in MySQL and the steps we need to perform to try saving our database.
MySQL Replication is a very common topology, widely used in various architecture.
People use it, among others, for High Availability, Read Scalability or Geographic Redundancy.
Another use case is to use MySQL Replication to seamlessly integrate a newer version of the server in your architecture.
Let’s say you are running MySQL 5.7 then you can easily setup a 8.0 instance as a replica of your 5.7.
Extending this idea it is also possible to replicate your MySQL 5.7 (or 8.0 obviously) to a MySQL Database Service instance, the true MySQL PaaS on Oracle Cloud Infrastructure.
In this article, we are going to see how to set up a MySQL Database instance on Microsoft Azure Cloud.
In one of our previous articles – Setting up Replication with various methods for MySQL 8 – we reviewed how to create a replica with multiple tools.
Now, it is time to perform the same action but with MySQL Shell.
In the world of the Databases, one of the most important value that we are all trying to achieve is High Availability. Not to loose our valuable data or in case one server fails to always have another to step in and take control.
So, it is critical to have along with our primary database, other identical instances, the replicas.
On this blog post, we will see the most famous ways to set up our replication.
Cloud backup is a strategy increasingly used in organizations. Send copies of your data to the cloud, can help you to prevent a devastating IT crisis and ensure business continuity.
Currently, MySQL Enterprise Backup supports the following types of cloud storage services:
– Oracle Cloud Infrastructure (OCI) Object Storage
– OpenStack Swift or compatible object storage services
– Amazon Simple Storage Service (S3) or compatible storage service
Since MySQL 8.0.22 there is a mechanism in asynchronous replication that makes the receiver automatically try to re-establish an asynchronous replication connection to another sender, in case the current connection gets interrupted due to the failure of the current sender.
