On Tuesday, June 4th from 6 to 7 PM PDT (June 5th from 10 to 11 AM JST, June 5th from 3 to 4 AM CEST) the databases supporting the Presto JDBC/ODBC Gateway, Workflow, and Audience Studio will undergo a short maintenance. The maintenance is necessary to upgrade the PostgreSQL database engine with the latest patches (including security related ones).
During maintenance window, each database will experience failover, after which the respective systems are expected to recover in approximately 5 minutes. During the failover period, customers will observe the following symptoms:
- Queries submitted through the Presto JDBC/ODBC Gateway will receive timeout errors.
- Scheduled and running Workflows will experience delays in execution.
- In the Console, Data Workbench and Audience Studio will incur in errors caused by failures within the underlying Master Segments, Segments, and Workflows.
Beyond this notice, we will provide updates approximately 1 hour before the beginning of the maintenance window, at the start and completion of the operation, and once the verification is completed. At that time, all systems will have returned to full functionality and the Scheduled Maintenance will be closed.
If you have any question or concern about this upgrade, please feel free to reach out to our Support team at email@example.com
