Automate Data Moment from Teradata Database to Snowflake

Introduction:

As the technology is vigorously moving towards the cloud, the data movement from on premise to the cloud has become arduous work, automating it is how to make it fast and easy.

In this article, we will see, how we will make the data movement easier from Teradata to Snowflake using the python code.

Pre-requisite:

To connect from on premise Teradata to Snowflake, we must have the below things

  • Installed Teradata system
  • Python and required access
  • Credentials to connect to Teradata
  • AWS S3
  • Snowflake to connect using python.

Steps to migrate data from Teradata to Snowflake:

  1. Initially, the source is going to be on premise Teradata where data will be stored.
  2. Using Python – Data is going to be loaded from on premise Teradata to S3 bucket
  3. The data from the S3 bucket is going to be loaded to the snowflake.

Step1:

MIGRATING DATA FROM TERADATA TO EXCEL:

To move the data from Teradata to S3, the first step is to move the data into S3 using Excel and Python

Step2:

MIGRATING DATA FROM EXCEL TO SNOWFLAKE:

The second step is to move the data from the S3 bucket to Snowflake which can also be done by using Python, which reads and copies the data from excel files in S3 and insert it into the target table.

Advantages:

  • Easy way to move data from Teradata(on premise storage) to Snowflake (cloud storage)
  • Coping up with the newest technologies.
  • By moving data to the cloud will have the advantages like
    • Improved performance.
    • Drastically better scalability.
    • Ability to support new use cases.
    • Ease-of-use and developer time.

Conclusion:

The automated migration process tends to possess more efficient and error-free migrations by using the foremost used programming language Python.  Which successively, reduces the man-hours utilized within the manual data migration process.
