Hi,

I am facing an issue with the size of the firebird database file.

I run a data upload process that loads data from series of XML files
(around 70 GB+ data) into Firebird 1.5 Database via a .net application.

The process takes atleast 10+days to complete but when I check the
database file size, it is 5 times greater than the total xml file size.

To speed up the process I load lots of data into temp tables and then
delete the records from them for each xml file I load. However I think
the delete doesn't shrink the database size.

Then I tried backup and restore, where the database file size got
reduced drastically.



Can someone please let me know how I can reduce the database size when
the delete is fired? This is because my application is going to receive
daily data updates of minimum 40 MB and the same process is going to
run. But that could cause concerns as the database size may exceed the
harddisk size and every time a backup and restore will have a large down
time on an online application.



Regards,
