@brent_shreve @Abtin hi I’m Nate, the engineering manager for the team that manages query execution. This was a bug that was the result of a change with how we do some simple bookkeeping during the process of looking up a query when trying to render a dashboard. I’m using the past tense because this has been resolved internally and these will not be seen once we ship our patches over the next few weeks.
To provide more detail: In this case the system is asynchronously asking only the cache (hence cache_only_miss) for a query and doesn’t find it. We make these kinds of request to our cache to help dashboards render quickly. The queries do eventually get run, but only later in a dashboard’s lifecycle.
Let me know if that helps,
