strange behaviour with CloudFetch

先從偵錯記錄中提到的 CloudFetchQueue、ResultFileDownloadManager、ResultSetDownloadHandler 和 FetchResults 入口開始，然後重現大型 Azure Databricks 查詢。追蹤最終列偏移處的轉換，並驗證完整的結果擷取是否在沒有已回報的檔案遺失警告或無法解釋的延遲的情況下完成。

Hi,

i have created a small python-script to fetch data from the sql-endpoint in azure databricks. The queried view has 2126641 rows. As you can see, CloudFetch serves batches as files as expected. Also the performance and data-throughput is very good until this line:

2024-11-27 05:35:22,038 - DEBUG - CloudFetchQueue: Cannot find downloaded file for row 2126641

It tries to fetch a file for the last position, what fails. After that, there is obviously a gap of 22 seconds, where seemingly nothing happens. When monitoring the network-traffic, you can see that until that point, i have full throughput of my internet-connection. After this point, nearly no more network-activity until the connection was closed. I did this test, because i experienced a similar behaviour over a ODBC-Connection with Simba Spark-Driver, where also CloudFetch should be used. So i am not sure if this behaviour is special to the API-Connection and databricks-sql-connector or if this is a general problem with CloudFetch or if this is intended and why it should be?
Any thoughts about this?

tested with databricks-sql-connector 3.6 and python 3.9 as well as with python 3.12.5.
