Too many calls in parallel to the SPARQL endpoint

[maximelefrancois86]

While using sttl.js in project https://wot-td-ontology.github.io/wot-thing-description

I experience freezing when too many calls are made in parallel to the SPARQL endpoints Fuseki. (cannot even kill the process --> I need to restart my computer)

I would like to fork STTL.js to make the calls to the SPARQL endpoint sequential (don't care about performances at this stage). Any idea how this should be done in the file sttl.js ?

You can drastically reduce the amount of calls by calling built-in SPARQL functions from JS instead of constructing a query (see sttl.evaluateOperation()). It's been on my list for some time.

(For the record: I remember that it finally worked on your machine after you redirected the standard output to a file, so it is likely a configuration to change in Fuseki to be less verbose rather than something to change on the STTL lib.)
