Disk buffering span exporter to avoid data loss (existing Java feature)

What problem do you want to solve?

The current span exporter offerings may drop spans under high traffic if the buffer overflows.

Describe the solution you'd like

I am looking for a Python version of the disk buffering span exporters that were released in Java (https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/disk-buffering). These exporters store telemetry data in files which can be sent later on demand. There is a thread buffering the spans to a disk and a thread reading the spans from the disk.

Describe alternatives you've considered

Writing a custom span exporter that uses queueing/local storage to avoid overload, which would be complicated.

Additional Context

Would you like to implement a fix?

None

Start with the linked Java disk-buffering implementation and the existing Python span exporter offerings. Define how spans are written to files, buffered by one thread, and read for later delivery by another. Done means a Python exporter avoids span loss when its in-memory buffer overflows and sends stored telemetry later.
