Scheduled
We would like to inform that our Metadata database will undergo maintenance today October 1st between 8pm and 9pm PDT. We expect the maintenance operation to cause NO downtime, however we'd like to announce this operation for full transparency with our customers.
All components reading/writing the Metadata database have a built-in fault tolerance mechanism that will allow them to retry the database access should it fail during the operation and for a while after; in particular, the execution of queries should continue as usual although the dispatching of new queries may experience a temporary slowdown during the maintenance window. After the maintenance operation, the database is expected to come back within less than 30 seconds.
