1.0.0 Prerelease Demos

About this repository

The included scripts and notebooks are intended to give a quick look at API changes in 1.0.0. Scripts that use postgres all use the same postgres image described below. Demos and scripts are found under the associated gx-<VERSION> directory, and a corresponding requirements.txt is included in each that pins the great_expectations version.

Running PostgreSQL

We've prepared a dockerized PostgreSQL with sample data that you can run with the command:

./scripts/run_dockerized_pg.sh

If you want to connect to the database to manually execute SQL queries you can run:

./scripts/psql_dockerized_postgres.sh

This psql script has the connection string if you would like to use a different tool to connect to the database.
