The Best Way to Host MySQL on Azure Cloud


Are you looking to get started with the world’s most popular open-source database, and wondering how you should setup your MySQL hosting ? While Microsoft Azure does offer a managed solution, Azure Database, the solution has some major limitations you should know about before migrating your MySQL deployments. The first thing to consider when weighing between self-management and a MySQL Database-as-a-Service (DBaaS) solution is what internal resources you have available.

MySQL Tutorial – Understanding The Seconds Behind Master Value


Understanding Execution Speed of the MySQL Slave. Assuming that the SQL Thread and IO Thread on the slave are in running states, it’s possible to understand the relative execution speeds of the master and the slave by monitoring the SBM value. A consistent ‘0’ value or a constant value indicates that the slave is executing at the same speed as the master.

MySQL High Availability Framework Explained – Part II: Semisynchronous Replication


Managing The Execution Speed of The Slaves. With these settings, we will be able to get better parallelization and speed on the slave, but if there are too many parallel threads, the overhead involved in coordinating between the threads will also increase and can unfortunately offset the benefits. This is explained in detail in J-F Gagné’s blog where he refers to this behavior as ‘ slowing down the master to speed-up the slave’.

Top Redis Use Cases by Core Data Structure Types


Depending on how it is configured, Redis can act like a database, a cache or a message broker. It’s important to note that Redis is a NoSQL database system. This implies that unlike SQL (Structured Query Language) driven database systems like MySQL, PostgreSQL, and Oracle, Redis does not store data in well-defined database schemas which constitute tables, rows, and columns. 8 ranked database on DB-Engines with a score of 144.08.

While current network speeds may be enough to meet the latency requirements of 4G applications, 5G will necessitate a change, if only because the continental US is ~60ms wide, meaning that a datacenter on one coast communicating with another datacenter on the opposite coast will be too slow for 5G.
