Yes, it's a good idea.
TDB2 in Fuseki has the "compact" operation to do this without stopping
the server. It creates a new "Data-NNNN/" directory and you can delete
lower numbered databases.
TDB1 - needs the server stopping for a rebuild. If you can stop
updates, stop updates, 9server now read-only) backup, rebuild from
backup then stop the server and swap the databases.

Hi,
we have now 13M triples and space usage of Jena data folder is 88G
which seems high. This is not including text index.
Should we cleanup/compress/rebuild etc the database regularly in
order to keep disk usage lower, or is this normal disk usage?
