Impact Description
For TDSQL-C for MySQL instances, the average I/O latency may increase by approximately 10% during the upgrade process and for up to four hours afterward. Under normal circumstances, latency spikes ("jitter") will not exceed 50 ms; however, isolated spikes of around 500 ms may occur with a very low probability. Database connections will not be interrupted during this period.
Please monitor your application status closely. We apologize for any inconvenience this may cause and appreciate your continued trust and support. Should you have any questions, please contact us via the Tencent Cloud Ticket System.
