Datasource scheduled refresh orchestration disruption
ResolvedPartial outage185 hours 44 minutes
  • ResolvedUTC
    This incident has been resolved.
  • IdentifiedUTC

    We identified the cause of the issue, caused by a failure in the behavior of our orchestration framework in a very specific situation created by last week database maintenance.

    The fix for this issue will be deployed in production on Thursday 15th of January.

  • InvestigatingUTC

    We’re currently experiencing an issue with the orchestration of the scheduled refresh operations of Sifflet data sources. Some sources might not get refreshed automatically according to their configured schedule (for instance "hourly", "daily" or "weekly").

    Manual refresh of data sources through the UI or the API is not impacted and works as expected.

    As a result and unless you trigger manual a refresh of your sources, your data catalog on the application might not represent the most recent state of the metadata of your data assets in your integrated platforms (for instance, the most recent tables, fields, tags, or lineage relationships might be absent).

    Our team is currently investigating the issue. We’ll provide updates here as the situation progresses.
