Manual Compaction #45
Description
One of my use cases involves building a large K/V dataset in one location, then closing the data store, transfering and replicating the contents to other locations and initializing them elsewhere.
For this use case, I would like to have a method to do manual compaction.
Perhaps a method void compact(float threshold) that compacts all data files that have more than threshold ratio of overwritten bytes would be best. For example, calling compact(0.01) would result in all files that have over 1% of their space deleted to be compacted.
This could be used for my use case as well as several others. It also would be a useful tool for compaction performance measurement.
