| Doc Text: |
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.
