Dear Snowflake Customer,


We have identified a problem that could produce incorrect results in some queries that perform memory intensive join operations. It is unlikely that this issue impacts you; however, we wanted to make sure you were aware of the problem. The issue was isolated to the US-West region between 2:19pm Pacific time on Tuesday, August 8th and 11:45am Pacific time on Wednesday, August 9th. Queries performed in other regions or outside that timeframe were not impacted.


Because of the nature of the issue, it is difficult for us to determine if any of your queries experienced the problem. However, we are able to perform further analysis on a query-by-query basis. If you have a question about whether a specific query was impacted, please submit a support request to Snowflake support via the Support Portal or via email to support@snowflake.net .


We are very sorry about this issue and will do everything possible to help you resolve any problems this may have caused you.
