dataSource.json

dataSource.json

Describes the data sources. Users need to plugin information about their data repositories. The system would use the information to access the data and use it for creating the dashboards.

Consider the following example in which we're fetching data from 2 sources s1 and s2.

#!json
{
    "dataSourceAlias": "sourceJoin",
    "joinKey": ["A"],
    "dataSources": [
        {
            "sourceName": "s1",
            "sourceType": "csv",
            "options":{
                "path": "examples/newDataSourceConfig/data/data1.csv"
            },
            "dataAttributes": ["A", "B", "C"]

        },
        {
            "sourceName": "s2",
            "sourceType": "csv",
            "options":{
                "path": "examples/newDataSourceConfig/data/data2.csv"
            },
            "dataAttributes": ["A", "D"]
        }
    ]
}
