SQL Alchemy - Materialize Example

Run the example

1. Install requirements in a virtual environment.

   python -m venv venv
   source venv/bin/activate
   pip install -r requirements.txt
   

2. Create a .env file to connect to Materialize. Here is an example:

   export MZ_HOST=<id>.<region>.aws.materialize.cloud
   export MZ_USER=chuck@materialize.com
   export MZ_PASSWORD=<app password>
   export MZ_PORT=6875
   export MZ_DB=materialize
   export MZ_CLUSTER=chuck
   export MZ_SCHEMA=public
   export MZ_TRANSACTION_ISOLATION=serializable
   

3. Create a table in Materialize (e.g. from the Console SQL Shell).

   create table t (id int, content text);
   insert into t values (1, 'hi'), (2, 'hello');
   

4. Run the application.

   python app.py
   

   Output:

   ID: 1
   Content: 'hi'
   
   
   ID: 2
   Content: 'hello'
