Storage jobs slowdown on Snowflake Multitenant stacks

We are investigating issues with slowdown of Storage jobs on Multitenant stacks. There are affected projects which are using Snowflake (Bigquery not affected). Issue was firstly noted on 10.07.2025.

The issue has impact on transformations with bigger backend size than default. 

We are preparing fix so the jobs are running as before.

Update 18:45 18.07.2025 UTC - We have released fix, which seems to be working correctly. We will continue monitoring the situation that the performance of transformations is back on track as before.

Update 07:07 19.07.2025 UTC - The root cause is fixed and the transformations on different backend size than default and performance seems to be on track as it was before.
