There's no table compacting mechanism as yet in IDB. The only way to compact
a table at present is to export its contents, drop it, recreate and
re-import. It's not as bad as it sounds, once you have a script for it you
can run it as often as needed. Something like:

set export "tmp.cvs" csvdelimited;
select * from tmp;
set export "null";

drop table tmp;
create table tmp (...);
import "tmp" from "tmp.cvs";

You might also want to look at the database property, searchDeletes. This
may produce more compact tables when all rows get updated. See

http://instantdb.enhydra.org/software/documentation/props.html

for details.

Subject: InstantDB: unusual growing of table size


> There is an instantdb database with a table including about 1600
> entries. After a few update operations on all rows the size of this
> table grew from 2,5 MB to 7 MB. There are no indexes, no foreign keys,
> no triggers. The update operations simply changed the values of columns
> ( all double). Now the operations on this table are getting real slow.
> Is there something like VACUUM, to "clean" the table?
