If you drop a table the underlying files should have been gone. If you delete, the files remain but will be empty. [Aside, we noticed some memory leakage, which has been attacked recently. This has been resolved in the bug-fix release emitted 2 days ago] Suggested quick approach.

Currently, distribution would have to be taken are of in the application/middleware.

Yes, array based support is part of our research agenda for some time for information retrieval. The latest paper available from the website: R. Cornacchia, S. Heman, M. Zukowski, A. P. de Vries, P.
