Jakub Dorňák 2016-02-11 10:45:11 UTC Doc Text Cause:
Race condition may occur when more than one INSERT is executed concurrently on a non-empty InnoDB table with an AUTO_INCREMENT PK immediately after MySQL start up.

Consequence:
One of the concurrent INSERTs fails with Duplicate key error.

Fix:
Applied patch prevents such race condition.

Result:
Each of the concurrent INSERTs gets unique PK.

Consequence:
One of the concurrent INSERTs fails with Duplicate key error.

Fix:
Applied patch prevents such race condition.

Result:
Each of the concurrent INSERTs gets unique PK.
When more than one INSERT operation was executed concurrently on a non-empty InnoDB table with an AUTO_INCREMENT column defined as a primary key immediately after starting MariaDB, a race condition could occur. As a consequence, one of the concurrent INSERT operations failed with a "Duplicate key" error message. A patch has been applied to prevent the race condition. Now, each row inserted as a result of the concurrent INSERT operations receives a unique primary key, and the operations no longer fail in this scenario.
