To UDFs and Beyond: Demonstration of a Fully Decomposed Data Processor for General Data Wrangling Tasks

To follow along with our demonstration simply clone this repository and run

docker-compose up

You'll now have a working JODA setup. You can access the web interface at http://localhost:8080.

You can find the language specification at https://joda-explore.github.io/JODA/

Additionally, does the example_queries.txt file contain some example queries that you can run in the web interface.

Example modules

The modules folder contains some example modules that you can use to get started with user-defined-modules JODA.

The included directoies are:

  • aggregation: Contains modules that can be used to aggregate multiple documents
  • export: Contains modules that can be used to export data from JODA
  • ìmport: Contains modules that can be used to import data into JODA
  • index: Contains modules that can be used to create custom indices
  • value: Contains modules that can be used to create user-defined functions for usage in the JODA query language

Database (optional)

If you want to experiment with the database connection modules you can run

./initEmptyDB.sh

to initialize an empty database with an empty table in it. The database will be initialized within the docker container started with the remaining JODA services.
