Assume while performing large SPARQL update, for example of triples around 80 millions in total, one gets the following error which aborts the update:
"Transaction aborted due to a database checkpoint or database-wide atomic operation. Please retry transaction" .
The error means that the SPARQL update has possibly encountered a database checkpoint during the load. Thus one should check the CheckpointInterval in the INI file and possible increase its value:
; ; Server parameters ; [Parameters] ... CheckpointInterval = 60 ...
Note: The RDF Bulk loader can be used for loading large datasets, and it will handle the checkpoint matter automatically.
