There is another pull request (#2497) for this feature but I thought I would try a different approach.
Motivation
In a constrained environment, we should be able to constrain the logging size and period.
Solution
Maximum bytes per log file may be specified in the
max_file_sizefunction when building the appender. The option will only be used when selectingRotation::SIZE.File size is checked every write and if the size is exceeded the log file is rolled over.
None of the other rotation types use sub-seconds in the logfile name but for size-based rotation, I used it since there could be a plethora of writes in a short period and this was the simple way to ensure filename uniqueness otherwise it would write to the same file even if the size was exceeded. This is a limitation since I tried to use the same methodology as the time-based rolling without rewriting the architecture.
