On 2021-01-27, between 01:15:00 UTC and 02:15:00 UTC (2021-01-27 02:15:00 and 03:15:00 CET) we are going to perform maintenance on the database underlying the Presto JDBC/ODBC Gateway component.

We will upgrade the major engine version of the database during the maintenance.

# Impact

During the maintenance window, we will stop the system for about 40 minutes during which customers may experience the following:

+ JDBC/ODBC queries which access “api-presto.eu01.treasuredata.com” will fail.
+ CDP segmentation UI queries ran from the Console will fail

Retrying the queries after the planned downtime is the suggested workaround. We expect the scheduled(in Workflow or in the Console) Presto queries to have no impact during this downtime.

If you have any question or concerns about this maintenance, please feel free to reach out to our Support team at support@treasuredata.com.
