Hi all,
a Java question to the smartest Java community in the world.
WO allows to quickly build HTML interface to a database so it seems reasonable
to use it to execute flexible data exports(XML or plain text for example).
However with Java(unlike C) it is not quite trivial if the tables(queries) are
large. I tried to export a subset of a large table using raw sql
EOAdaptorChannel methods. Even in that rather inexpensive case the memory
consumption after just 300 000 rows reaches 1 GB which is hardly acceptable.
Is there a means to deallocate memory(in this case the dictionaries returned
by EOAdaptorChannel.fetchRow()) in some predictable way or to force the
virtual machine to reclaim garbage ?
Or should i rather forget doing such things in Java ?
Thanks
Richard
