Introduction What is a rapid fire brute force attack? It is a trial-and-error approach used to obtain login passwords.  A hacker tries a multitude of username and passwords typically using code that tests a wide range of combinations until they find a login user and password combination that works.

Using “failed login” policies, dbas can prevent brute force rapid fire attacks on MySQL user’s passwords. This uses a technique know as “login throttling”. This method affectively thwarts these “rapid fire” login attempt attacks by increasing delays for each failed attempt. These policies are simple and straightforward to put in place and define. Enabling defense and detection of rapid fire and other password attacks.

Galera Cluster Enterprise Edition (EE) has had support for Non-Blocking Operations (NBO) schema upgradesever since the first release of Galera Cluster Enterprise Edition (EE). It is reasonably well documented, and we think more people will benefit from using it, of course. Schema changes tend to always remain a daunting task when you have large databases to manage.

To compare between Total Order Isolation (TOI), the default, with NBO that is available in Galera Cluster Enterprise Edition (EE), we create a test table:

CREATE TABLE large;
USE large;

CREATE TABLE test_table (
    id INT PRIMARY KEY AUTO_INCREMENT,
    data VARCHAR(255),
    num1 INT,
    num2 INT,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

Then we …
