QUESTION::LAKEHOUSE::SQL ENDPOINT::SYSTEM VIEWS
Hi Element115 ,
Run the following two commands in Notebook to calculate the table size in lakehouse.
The first command contains the table size in byte, my table is smaller, replace the products table with your own when using it.
%%sql DESCRIBE DETAIL delta.`Tables/products`The second command converts byte to GB, replacing 3213 with your own after running the first command.
size_in_bytes = 3213 # byte swtich GB size_in_gb = size_in_bytes / (1024 ** 3) print(f “Table ‘products’ size: {size_in_gb:.8f} GB”)Best Regards,

Hi Element115 ,
Some views are used internally for system operations and development purposes, and they might not be exposed for direct querying regardless of your license type or administrative privileges.
Just because a view is listed doesn’t mean it’s queryable.
Some views are for internal system use and not meant for direct access.
While a paid SKU and admin privileges generally provide broader access, they don’t guarantee visibility of all system views.

OK so what is the best way to find the total size in GB of one or more tables if we cannot query system views?
