When programmatically inserting mutations there is the concept of a transaction and the blank nodes from the mutations are recognised within the transaction. What does this transalte to when using the Bulk Loader? Is there something corresponding to a transaction? Are blank nodes in any way recognised between triples?
I am aware of the
--xidmap option, but have been unable to use it. It consumes way too much memory. As I understand it, it is a disk based cache and should be able to have limited RAM usage. Whenever I run the bulk loader with the
--xidmap option it consumes all available memory and eventually crashes.
discuss a possible option
--limitMemory. There is no such option in the current version, right?
With or without such an option there seems to be a problem with offloading cached id:s to disk so that memory can be limited. Is there perhaps a known bug here?
--xidmap option does precisely what we need, but we can’t use it.
