How It Affects Your App
MySQL 1637 ER_TOO_MANY_CONCURRENT_TRXS indicates that the application is trying to execute too many concurrent transactions at once. This can lead to performance issues, as the application may be unable to process all of the transactions in a timely manner. Additionally, it can lead to data integrity issues, as the application may not be able to guarantee that all of the transactions are executed in the correct order. This can result in data being corrupted or lost.
