Option to shrink unused space

Did not find any info on that, so decided to ask here - is there (or planned) an option to shrink (e.g. compact the database)?

We're using objectbox for quite a long time for a production app one entity there is used to collect various loggable information for further sending it to a server. Successfully sent entities gets removed from the database, however, the physical db file still grows constantly. (which is understandable)

I understand we can always delete the file before creating the ObjectBox instance in order to reduce the unused space, however there are other entities there so we'll need save and recreate them somehow in the new (emptied) datastore. Thus, kind of an option to the builder like .shrinkOnOpen() would be nice to have, so app may check the database size during the initialization process and shrink it when necessary.

Thanks!

Start by reviewing the datastore builder and database lifecycle APIs involved when an ObjectBox instance opens, along with how unused space is currently reclaimed. The issue's requested outcome is an optional operation that safely reduces the physical database file while preserving other entities; confirm the expected behavior and constraints in the comment discussion.
