How can I count an iceberg table using pure python? I went over the documentation and I could not find any recipe to do this easily. My use case is that I have over 10TB of data lying in GCP iceberg and I want to write a python script to tell me the total number of daily transactions that land in the table. I have heard that py-iceberg will help me do it only with the metadata and hence it is efficient. I would appreciate any code-snippets/blogs/documentations around this?
