A post close to my heart, Azure SQL Managed Instance, I have blogged about this many times but I feel I should be sharing more details about this. One important topic – Maintenance windows.
The concept of a geo-replicated partnership between a primary and secondary node is very similar to that of something you may have seen with Azure SQL DB, where the primary handles all R/W and then the changes are pushed to secondary ( async). This is no different with Redis.
Let’s go through a Redis build process. It will be fun.
Redis Cache is a well know caching technology and you can run it in Azure as a fully managed service. A common requirement (the most basic one) is doing a workflow like:
The query store, sounds familiar? The idea of the black box sitting within the database server watching what is going on within the environment. This is available within MySQL, maybe not as feature rich as SQL Server but still useful.
You will find this option under the Query performance insight section of your MySQL server.
If you have used MySQL before you will know about the system server variables, you know such commands as SHOW VARIABLES; You can access most of them via the Azure portal or connect to MySQL and issues the commands you come to know about.
When it comes to MySQL and storage you will normally have to decide on 3 options: basic, general purpose v1 or v2.
Basic does support up to 1TB and is low-cost option but has no IOPs guarantee, not really recommended for production systems. General purpose v2 should be the one used because it uses latest storage infrastructure which can support up to 16-TB and 20000 IOPs a shown below.
We have already created the server now it’s time to connect to it. What you will need – connection string details, correct networking setup and a tool like MySQL Workbench.
Enough of the theory and text lets use the Azure Portal and create MySQL Single server. Navigate to the Azure Portal, find Azure Database for MySQL servers:
When you start the build process for MySQL you will be shown the below screen, the question is what option would you select?
