Description

I am new to Apache, but here I am...

In our use case, we need to constantly update an existing avro file. The way we did it is that we copy the old avro file to a temporary file, append data to the temporary file, close the temporary file, and rename the temporary file to the original avro file. This is problematic since closing a file does not guarantee to write data to disk. The bug caused by this is hard to track since it's hard to reproduce.

I noticed that there is a ticket that addresses this for the Java client https://issues.apache.org/jira/browse/AVRO-1388. Why isn't it implemented for the Python client? If there are no objections, I'd like to submit a patch. Or perhaps I am missing something here? Please let me know!
