On 2020-10-15, between 03:20:00 and 04:50:00 UTC (2020-10-14, between 20:20:00 and 21:50:00 PDT) we are going to perform maintenance on the database underlying the Workflow component.

We will upgrade database engine to newer major engine version.

# Impact

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

Workflow REST API will be unavailable

Execution of running workflows and scheduled sessions will be delayed

Workflow tasks using blocking operators like pg> and redshift> will be delayed.

It won’t be possible to create or update CDP Master Segments, Batch Segments, API Tokens, and Predictive Scoring

Refresh of CDP Master Segments, Batch Segments, and Predictive Scoring will be delayed

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