You can schedule to run the process periodically and limit it either by maximum duration or amount of data.

The bridge saves profiling results in the MIMB cache as soon as possible. When it profiles multiple files, it saves profiling results of each file as soon as they are ready.

If the bridge fails, it can restart at the latest point available in the cache. When the bridge detects that the file did not change, it can update the profile time for the file.

The bridge tries to return as much as possible to the caller when it completes, fails or reaches the time or volume limit.
