Crossjoin joins together your data from anywhere.

Overview

crossjoin Docker CLI Security scan

Crossjoin joins together your data from anywhere.

  • Supports PostgreSQL, Redshift, CSV data sources
  • Zero dependency CLI, or a single Docker container

Example

In the example directory, there are two CSVs (adapted from this AWS blog post) representing orders and returns data.

The config defines a data set using both CSVs joined on the Order ID field. This example joins two CSVs, but you can mix and match data sources. For example, you can join a PostgreSQL data source with a different Redshift data source and a CSV.

data_sets:
  - name: joined
    data_source:
      name: orders
      type: csv
      path: ./orders.csv
    joins:
      - type: JOIN
        columns:
          - left_column: Order ID
            right_column: Order ID
        data_source:
          name: returns
          type: csv
          path: ./returns.csv
