GpJSON - Leveraging Structural Indexes for High-Performance JSON Data Processing on GPUs

This Truffle language exposes JSONPath query execution to the polyglot GraalVM.

The goals are:

1. Present a couple of parsing techniques based on structural indexes to quickly execute queries on JSON files
2. Introduce a batching approach to improve performance and allow the processing of datasets bigger than the GPU’s memory
3. Implement the above concepts into a Truffle Language to provide an engine that can be used from any host language that can run on the GraalVM.

Using GpJSON in the GraalVM

To compile JAR file containing GpJSON move to the language folder and run mvn package.

Next, copy the JAR file from target/gpjson.jar into jre/languages/gpjson (Java 8) or languages/gpjson (Java 11) of the Graal installation.

Note that --jvm and --polyglot must be specified in both cases as well.

In the examples folder you can find a couple of files containing examples of the GpJSON's syntax.
