Some Storer and Reader functions could be parallelized

[iosonopersia]

Functions from Storer and Reader that execute SPARQL queries (SELECT/UPDATE) or that access RDF files (read/write), could be parallelized in some way to achieve better performance.

Generally speaking, applications that make use of oc_ocdm often need to import/store/upload a large quantity of data. This usually consumes a lot of time, which often represents the biggest percentage of total execution time.

An initial optimization approach can be found in Storer.upload_all(...), where the total amount of UPDATE queries to be performed is grouped into batches of configurable maximum size (see batch_size parameter).
