Dear @VZLA , @Walter_C ,

Thank you for providing us with several solutions regarding our high Google Cloud Storage costs. We have confirmed that the high costs are indeed coming from metadata operations triggered by Delta table activity, with the GET and LIST operations significantly contributing to the expenses.

We also have been implementing all three strategies: Caching, Optimize, and Z-Ordering. However, we are not seeing a significant reduction in costs.

Could you please advise if there are any additional methods we could apply? Additionally, are there any specific considerations we should be aware of? We understand that this problem is difficult to solve, so your guidance means a lot to us.

Thank you for your assistance!

Best regards,

Hung.
