Project Description

The HPCC Systems platform currently supports embedding Python, Java, Javascript, R, MySQL and C++ and Cassandra code.The goal of this project is to support MongoDB by allowing the embedding of MongoDB database queries within ECL code running on HPCC Systems.

...

  • Implemented a simple example that passes and returns scalar values (which are usually much simpler than passing/returning structures).

Skills needed
  • Ability to code in C++.
  • Ability to build and test the HPCC system (guidance will be provided).
  • Knowledge of MongoDB sufficient to write and run test cases.
  • Ability to write test code. Knowledge of ECL is not a requirement since it should be possible to re-use existing code with minimal changes for this purpose. Links are provided below to our ECL training documentation and online courses should you wish to become familiar with the ECL  language.
Deliverables

Midterm

  • A simple example that passes and returns scalar values.

End of project

  • A plugin that supports interfacing to MongoDB from ECL, that will implement the ECL embedded language API and make calls to MongoDB embedded via its C/C++ api (assuming it has one!).
  • Test cases demonstrating the correct behaviour and performance of the plugin.
  • Documentation of how datatypes and structures in ECL are mapped to MongoDB.
