In this blog post, we are going to look into how to perform online migration from MySQL 5.6 standalone setup to a new replication set running on MySQL 5.7, deployed and managed by ClusterControl. 

The plan is to set up a replication link from the new cluster running on MySQL 5.7 to the master running on MySQL 5.6 (outside of ClusterControl provision), which uses no GTID. MySQL does not support mixing GTID and non-GTID in one replication chain. So we need to do some tricks to switch between non-GTID and GTID modes during the migration.

Our architecture and migration plan can be illustrated as …

We’ve been receiving requests recently from MySQL users wanting to understand how InnoDB Cluster compares to Tungsten Clustering, our MySQL HA, disaster recovery, and geo-clustering solution. In response we have come up with this comparative outline, looking at some of the key features of each.

Two questions from Reddit’s /r/mysql related to Window Functions: How do I make row.numbers happen and Get the difference between two values in different recordings.

One of the new things in MySQL is the implementation of Window Functions. They are related to aggregates, but do not actually lump values together.

To better understand what goes on, let’s create some fake data to work with:

#! /usr/bin/env python3
# -*- coding: utf-8 -*-

import MySQLdb as mdb
import MySQLdb.cursors as cursors
from datetime import datetime, timedelta
from random import randint, random

# We have {sensors} sensors, each producing {values} values 
# between {minvalue} and {maxvalue}, at a random time after {starttime} …

MinervaDB Webinar – MySQL Backup Strategies and Tools 

Most often Database Systems outages happen due to user error and it is also the biggest reason for data loss / damage or corruption. In these type of failures, It is application modifying or destroying the data on its own or through a user choice. Hardware failure also contributes to database infrastructure crashes and corruption. To address these sort of data reliability issues, you must recover and restore to the point in time before the corruption occurred. Disaster Recover tools returns the data to its original state at the cost of any other changes that were being made to the data since the point the corruption took place. MinervaDB founder and Principal, hosted a webinar (Thursday, June 18, 2020 – 06:00 PM to 07:00 PM PDT) on MySQL backup strategies and tools addressing the topics below:

• Proactive MySQL DR – From strategy to execution
…

In recent years, the use of platform infrastructure has shifted from on-premise to cloud computing. This is based on the absence of cost capital costs that must be incurred by the company if used when implementing IT infrastructure. Cloud computing provides flexibility in every line of resources ie. on human resources, energy, time savings.

Cloud computing makes it easy for organizations to do IT planning, executing, maintaining platforms to support business interests.

But both have similarities, we had to think about BCP (Business Continuity Plan) and Disaster Recovery Plan (DRP) when using the cloud. Data storage becomes critical when we talk about DRP, how fast we do recovery (Recovery Point Objective) when a disaster occurs. Multi-cloud architecture plays a big role when we want to design and implement infrastructure in the cloud environment. In this blog, we review the related multi-cloud deployment for storing data in …
