Benchmarking is a critical technique for delivering high performance software. The basic idea behind benchmarking is measuring and comparing the performance of one software version against another. Over the years, many benchmarking techniques have emerged, but we can broadly separate them into two categories: micro and macro benchmarks. Micro-benchmarks measure a small part of the codebase, usually by isolating a single function call and calling it repeatedly, whereas macro-benchmarks measure the performance of the codebase as a whole and run in an environment similar to what end-users experience.

“It would be nice to have an option, that would allow to suppress the DEFINER statement in the CREATE VIEW statements generated by mysqldump. This would help when transferring data structures between databases with different security models.” 

TLDR;

Use mysqlpump with option

--skip-definer

instead of

mysqldump

Recently I blogged about how to easily deploy a LAMP application to MDS.

Using the Terraform module (OCI Resource Manager’s Stack) you also have the possibility to choose the PHP version to install:

In this post I will show how to program a C++ client for MySQL NDB Cluster. I have already presented MySQL Cluster, the distributed database using the in-memory storage engine, in several occasions. You may have learnt how to configure and start MySQL Cluster, so I will assume that a cluster is up and running. If you want to develop a simple C++ client, just run the cluster in a single host, which may be your very laptop. In order to compile an NDB API client, you will need.

1. MySQL NDB Cluster installed. Community distributions are here (I like to work with the self contained TAR).
2. The cluster up and …

One of the new features introduced in MySQL 8.0.24 was the ability to log all SQL statements that are issued in the MySQL Shell to the system log. This is a useful feature that can greatly assist in tracking who did what on the system.

Usage

The simplest way to utilize the new Shell logging feature is to simply start the MySQL Shell with the syslog option enabled like so:

$> mysqlsh --syslog --sql root@localhost

From this point forward all SQL entered in the MySQL Shell will be logged to the system log. For example, the following SQL is entered into the Shell:

MySQL  localhost:33060+ ssl  SQL > show databases;

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
+--------------------+

We can now check the system log and verify that the statement above was indeed logged …
