Over the weekend, our data storage and querying fleet experienced a partial degradation starting Sunday afternoon. As a result of a resource leak, some data was unable to be properly compressed on halves of our mirrored pairs, causing our metadata to be out of sync with our data. This incorrect metadata resulted in partial results being returned for some queries against the affected data.
After discovery, we identified the resource leak, and repaired the incorrect metadata causing queries to return partial results. No customer data was lost as a result of this incident.
