title: External table snowflake refresh issue /questions / confirmation / with external stage on azure plateform
body: <p>I am looking for small help in below snowflake scenario.</p>
  <p>Going by snowflake official documentation its clear that external tables needs to refresh at least once(auto or manual) so that its setup is completed and query should be able to fetch rows.</p>
  <p>What happens in case where underline path and filenames is not changing, but we are replacing the file with new data. Whether new data will be available if we query the external table from snowflake
  without event grid setup (which perform refresh) or without performing manual refresh. ?</p>
  <p>ex . some_external_path/location/file_with_data.csv</p>
