Adding a new Cassandra table

To load the contents of a new Cassandra table into the Curation API, follow these steps:

• If the keyspace isn't loaded into Curation yet, add a config in src/api/keyspaceConfigs
• Add a new query config containing the fields as lists by field type to src/api/queryConfigs (can be reused if the new table has the same structure as a previous table)
• Add a new model file containing the fields, primary key and table name to src/api/models
• Add the model's name, source path and table name to the schema config of the corresponding keyspace in src/api/schemaConfigs/<KEYSPACE_NAME>Config.js
• Import the new query config (if any) at the top of src/server.js
• Choose an API route, add it to a new app.use call at the bottom of src/server.js, containing a modelRouter call with the correct keyspace models, model name and query config, e.g.: app.use('/api/subjects', modelRouter(datalakeModels, 'Subject', subjectsQueryConfig));

As a reference for the structure of these files refer to the other files in the corresponding directories.

To query the newly created API endpoint in the Curation frontend, do the following:

• Add a new duck to src/ducks, which contains the actions querying the chosen API route and the reducers that store this data
• Add this duck's reducer to src/ducks/reducers.js (also import it at the top)
• Connect to the corresponding Redux store at the bottom of a React component by using the connect() and bindActionCreators() calls from react-redux
• Use the data from this.props inside the component (maybe check for changes inside componentWillReceiveProps() if necessary)
