This topic describes the event types supported in the event center of AnalyticDB for PostgreSQL and their business impacts.

Event type Impact Description
Minor version update Service interruption After a switchover is performed at the scheduled switchover time, you may encounter the following impacts:
  • Your instance or one of its relevant data shards experiences a service interruption and stays in the read-only state within 30 seconds before all data is synchronized. We recommend that you perform the switchover during off-peak hours and make sure that your application can be automatically reconnected to your database system.
  • Operations of your instance are affected in DMS and DTS. The impact is eliminated after the switchover is complete.
Differences between minor engine versions Different minor engine versions provide different updates. For information about differences between minor engine versions, see Engine release notes for elastic storage mode.
