Hello everybody.
I tried to import a graph contained in the file "clinicaltrials.nq.gz". The
file is rather big as it has a size of about 2GBs. I followed the process
described in
http://virtuoso.openlinksw.com/dataspace/doc/dav/wiki/Main/VirtBulkRDFLoader
.
Everything was going Ok for one day or so. I checked the loading process at
some point and the new graph contained 63649311 triplets. One day after, I
checked again and the graph contained 31133122 triplets (less than one day
before)! I checked the table DB.DBA.LOAD_LIST and it showed no error on the
importing procedure that it was still going (ll_state was 1).
I considered the above described situation as invalid and checked the VM
that Virtuoso was running. The disk is full with a
/usr/local/var/lib/virtuoso/db/virtuoso.db of size 50522488832. When I
removed the newly installed graph, the file of the size has not reduced at
all!!!
I have two questions:
1. Since I deleted a huge amount of triples, I would expect the database's
file size to be reduced. Am I right? How could I free the respective disk
size?
2. How could it be explained that while importing a triples file, the
triples number is decreasing? As the DB.DBA.LOAD_LIST provides no
information, is there a log file that I could check to see the error?
I am using a Version: 07.20.3214, Build: Oct 14 2015 (I built it from
source files).
Kind regards,
Pantelis Natsiavas
