[Bigdata-developers] Journal remaining large after performing SPARQL UPDATE queries

[Reul, Q. <que...@wo...>]

Hi,

We are using Blazegraph 1.5.2 as part of a project. As part of our assessment, we are observing that the size of the Journal is not only rapidly increasing, but also that it does not seem to decrease in size after performing SPARQL UPDATE queries. For instance, we do a clean up of the repositories every so often using
               DELETE {
        ?s ?p ?o .
     } WHERE {
        ?s ?p ?o .
      }
Although this query removes the triples, it does not seem to have any impact on the size of the Journal. Looking at the JIRA [1], I see that a recommendation is to do a data import / export. Is there any configuration that can be applied such that the Journal gets purged after removing triples?

Kind regards,
