Hi, I am running the latest MonetDB 11.13.3. I loaded a pretty tiny RDF dataset of 13 million triples and created some "vertical partitions" on predicate values. After having done dataset loading, I checked the size of the dataset folder and it showed to be _258 MB_. Then I ran about 6000+ bulk queries by periodically shutting down the server after about 1000 queries each time. The queries finished successfully and there was no crash. After the final query I stopped the database "monetdb stop dbname" and shutdown the main server too "monetdbd stop /path/to/dbfarm". After that I again checked the size of the database folder and then it showed it to be _5.8GB_ and the "HC" folder under "bat" was shown to have size of about 3 GB with some other files having sizes between 300-700 MBs. It seems mysterious to me why would the size of database go on increasing as much as 25 times the original size. I intend to load much larger data (> 1 billion triples), and want to avoid growing disk size of the dataset due to limited disk-space. Can someone please enlighten?
