> When accessing a MySQL database through a proxy that has a set timeout, an
> error occurs when using {{{}df.write.mode(SaveMode.Append).jdbc(url, table,
> properties){}}}.
> error msg : !image-2024-11-25-16-22-01-206.png!
>
> The reason for this error is that the JdbcRelationProvider created a
> connection on the driver side, but did not close it after use; instead, it
> was closed after the saveTable method was called. At this point, Nginx
> detected that there was no data transfer on the connection and directly
> closed the connection, leading to an error when calling conn.close(): "no
> more data to read from socket".
