Timescale Cloud: Performance, Scale, Enterprise

Self-hosted products

MST

Amazon SageMaker AI is a fully managed machine learning (ML) service. With SageMaker AI, data scientists and developers can quickly and confidently build, train, and deploy ML models into a production-ready hosted environment.

This page shows you how to integrate Amazon Sagemaker with a Timescale Cloud service.

To follow the steps on this page:

Create a table in Timescale Cloud service to store model predictions generated by SageMaker.

  1. Connect to your Timescale Cloud service

    For Timescale Cloud, open an SQL editor in Timescale Console. For self-hosted, use psql.

  2. For better performance and easier real-time analytics, create a hypertable

    Hypertables are PostgreSQL tables that automatically partition your data by time. You interact with hypertables in the same way as regular PostgreSQL tables, but with extra features that makes managing your time-series data much easier.

    CREATE TABLE model_predictions (
    time TIMESTAMPTZ NOT NULL,
    model_name TEXT NOT NULL,
    prediction DOUBLE PRECISION NOT NULL
    ) WITH (
    tsdb.hypertable,
    tsdb.partition_column='time'
    );

    If you are self-hosting TimescaleDB v2.19.3 and below, create a PostgreSQL relational table, then convert it using create_hypertable. You then enable hypercore with a call to ALTER TABLE.

  1. Create a SageMaker Notebook instance

    1. In Amazon SageMaker > Notebooks and Git repos, click Create Notebook instance.
    2. Follow the wizard to create a default Notebook instance.
  2. Write a Notebook script that inserts data into your Timescale Cloud service

    1. When your Notebook instance is inService, click Open JupyterLab and click conda_python3.

    2. Update the following script with your connection details, then paste it in the Notebook.

      import psycopg2
      from datetime import datetime
      def insert_prediction(model_name, prediction, host, port, user, password, dbname):
      conn = psycopg2.connect(
      host=host,
      port=port,
      user=user,
      password=password,
      dbname=dbname
      )
      cursor = conn.cursor()
      query = """
      INSERT INTO model_predictions (time, model_name, prediction)
      VALUES (%s, %s, %s);
      """
      values = (datetime.utcnow(), model_name, prediction)
      cursor.execute(query, values)
      conn.commit()
      cursor.close()
      conn.close()
      # Example usage
      insert_prediction(
      model_name="example_model",
      prediction=0.95,
      host="<host>",
      port="<port>",
      user="<user>",
      password="<password>",
      dbname="<dbname>"
      )
  3. Test your SageMaker script

    1. Run the script in your SageMaker notebook.

    2. Verify that the data is in your service

      Open an SQL editor and check the sensor_data table:

      SELECT * FROM model_predictions;

      You see something like:

      timemodel_nameprediction
      2025-02-06 16:56:34.370316+00timescale-cloud-model0.95

Now you can seamlessly integrate Amazon SageMaker with Timescale Cloud to store and analyze time-series data generated by machine learning models. You can also untegrate visualization tools like Grafana or Tableau with Timescale Cloud to create real-time dashboards of your model predictions.
