Maintenance schedule API endpoints

We've added new API endpoints for viewing maintenance schedules on Vitess databases. You can now list maintenance schedules, get details about a specific schedule, and view maintenance window history through the API. /v1/organizations/{organization}/databases/{database}/maintenance-schedules — List maintenance schedules for a database (GET) /v1/organizations/{organization}/databases/{database}/maintenance-schedules/{id} — Get details about a specific maintenance schedule (GET) /v1/organizations/{organization}/databases/{database}/maintenance-schedules/{id}/windows — List maintenance windows for a schedule (GET) These endpoints are available for Vitess Enterprise customers. To use them with a service token, grant your token read_database permission.
