Sep 20 15:15 UTC: We are experiencing degraded performance on our GCP EU stack (https://connection.europe-west3.gcp.keboola.com/). We are deeply sorry for the inconvenience this may cause and appreciate your patience as we work through it. We will provide further updates as soon as we have more information.
Sep 22 18:53 UTC update:We have gained additional understanding of the performance degradation. The root cause seems to be in intermittent slowdown of query execution on Snowflake. While the execution of single query is not delayed significantly, the delays do accumulate to noticeable slowdowns of minutes on transformations consisting of multiple queries and even more for entire flows. We're in touch with Snowflake support in the process of uncovering all the technical details.
The symptoms of the performance degradation include longer running times of jobs - especially on Snowflake transformations, but Data Source jobs and Data Destination jobs are also affected, because they load/unload data from a Snowflake database. The performance degradation occurrence is random and somewhat time dependent so not all flows are affected in the same manner. The performance degradation does not cause any errors.
Sep 24 07:10 UTC update: We have now confirmed the root cause to be in slower execution of Snowflake queries at certain times. We have implemented a temporary resource increase to improve the situation. This means that you should see improved job run times. We're still working with Snowflake support on the solution.
Oct 1 7:54 UTC update: We are still working on the resolution together with Snowflake support. The temporary resource increase is still in place. This means that that the situation is contained and overall stack performance should be acceptable, but not perfect.
At this moment we don't have a solution ready, nor an ETA for one. Thank you for your understanding and patience. We will provide further updates as soon as we have more information.
