In most of queries a LIMIT argument will help to handle bigger data sets. Specially for (values) queries.

Yes indeed this is needed! We need to adopt a LIMIT strategy for all the queries

In README file limit is taged as optional for slice? query, but if not provided you get a null pointer exception error as follows:

HTTP ERROR 500 Problem accessing /slice. Reason:

Server Error
