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!

首先查看 ObjectBox 实例打开时涉及的 datastore builder 和数据库生命周期 API，以及当前如何回收未使用的空间。issue 要求的结果是一项可选操作，在保留其他实体的同时安全地缩小物理数据库文件；请在评论讨论中确认预期行为和约束条件。
