Periodic maintenance is a mandatory component of the FPT Database Engine service, designed to maintain a healthy operational state for database clusters. It is a core part of the managed DBaaS offering and is not an optional feature.
Through periodic maintenance, the system ensures:
Important Notice:
During the maintenance period, do not perform any operations on the database server, including but not limited to:
Performing these actions during maintenance may negatively impact performance and stability, or result in unexpected errors. Users should only resume operations after the maintenance process has been completed.
The Maintenance Window allows users to configure a preferred weekly time slot during which the system performs periodic maintenance with minimal impact on service operations.
If no Maintenance Window is configured, the system automatically schedules maintenance to start at 23:00 every Saturday by default.
Users may modify the Maintenance Window if the database cluster does not yet have a scheduled maintenance event. Note that while the Maintenance Window helps optimize the timing of maintenance activities, it does not guarantee zero service interruption. It is recommended to schedule maintenance during off-peak hours to minimize service impact.
The system sends email notifications to help users proactively track maintenance schedules, including:
Notifications are sent to the email recipients configured in the service’s Notification settings.
During maintenance, the service may experience temporary impacts, including:
These impacts are minimized as much as possible and will end once the maintenance process is completed.
FPT Database Engine provides mechanisms that allow users to manage and monitor maintenance activities, including:
For detailed instructions, refer to Maintenance Window section.
In special cases, such as critical security patches or important system updates, emergency maintenance may be performed outside of the configured Maintenance Window to ensure data security and system stability.
