Is there a function of "drop table" or "delete from table"?

Besides the em.remove() one by one, is there a function of "drop table" or "delete from table"? TIA ... manual, since "drop table" is often in debugging. I can not find "drop table" in this site BTW ... ! "drop table" or "delete from table" or "truncate" can clear the id counting. Any idea? Resetting

Drop JDO support

In my opinion JDO is a legacy/deprecated technology. You should remove JDO support in favour of JPA. I think this would make ObjectDB to grow faster.
