Hi,

- The table size is about 2 TB.

- I had already set the liquid clustering keys before creating the materialized view. There were no issues with automatic liquid clustering.

- The issue with the liquid clustering keys not appearing in the metadata has been resolved. About a day after opening this post, the keys appeared in the metadata correctly.

- The slow performance issue persisted for quite some time. However, it now appears to be resolved. The view’s performance is currently the same as the streaming table version of the same data.

I was not able to determine the root cause, but the issues seem to have been resolved.
