Teradata has been a leading solution provider in the data warehousing space for decades, with many customers and workloads running on its solutions.

DATA TYPES REDSHIFT HOW TO

In this post, we provide an example of how to integrate these two technologies easily and securely.Īt a high level, the architecture looks like the following diagram:įigure 1: Teradata to Amazon Redshift migration using AWS SCT agents Once both source and target schemas are in place, you can use AWS SCT to set up agents that collect and migrate data to the target Amazon Redshift schema.

With this capability, you can easily integrate Teradata schemas into an Amazon Redshift model. Recently AWS announced support for Teradata as a source for the AWS Schema Conversion Tool (AWS SCT). As companies migrate to the cloud, they are using Amazon Redshift as part of their cloud adoption. Teradata provides long-standing data warehouse solutions, with many customers and applications running on its platforms. Below are the steps to set up and run the project (note: I had to make some changes to file locations and this may vary based on your setup).David Gardner is a solutions architect and Pratim Das is a specialist solutions architect for Analytics at Amazon Web Services. Next I am going to create a new AWS Cloud9 instance a virtual IDE that will allow me to run everything inside AWS using my credentials and upload the dbt project files I exported from Airbyte. Set up dbt in AWS Cloud9 and deploy model Follow these instructions from the documentation to generate the SQL files and then export the dbt files ( here is a guide to exporting the desired files from EC2 to S3). This will also allow you to export the files to upload to AWS and modify. Once the sync has run you can generate and run the dbt project and files within Airbyte. When we normalize the data we generate the dbt files which allow us to customize that step. Click on Source and enter the fields.Īirbyte is an ELT tool which focuses on extracting and loading the data as raw JSON then leveraging the destination to do the transformations at scale which Redshift is perfectly suited for using its scalable compute processing. The best way to do this is to host your file in S3 and connect it to Airbyte once it has been loaded.

DATA TYPES REDSHIFT INSTALL

You can install it in three steps locally with Docker or in AWS. You can find the instructions here and you should be ready in a few minutes. This is a simple process if you have Docker up and running. This makes the ingestion process easier especially if you have data that is regularly updated with the same data structure or if you have transformations you want to continually run on your data. From here you can create sources destinations and connections. That will install the system and allow you to access their user interface. You can install the open source version of Airbyte using docker in a few simple steps. It is an ELT tool (Extract Load Transform). One of my favorite tools I have come across recently is Airbyte. There are lots of options and parameters so make sure to check the documentation out to find all those options. Run the COPY command in Redshiftįinally just run the copy command in Redshift to fill your table with data from the CSV. Just open a text editor and remove the parentheses and number (“VARCHAR(96)” to “VARCHAR”) and that should fix the issue. I have sometimes experienced issues with the data in the CSV not perfectly matching that schema. Keep in mind that this will generate the file with specific values for the data types, such as VARCHAR(96). Updateddate TIMESTAMP WITHOUT TIME ZONE NOT NULL, To do so you can run this command in the file location on your computer:Ĭreateddate TIMESTAMP WITHOUT TIME ZONE NOT NULL,

DATA TYPES REDSHIFT MAC

Here is a guide to do so with Homebrew on a Mac and on Windows.įor this step we can create a geometry on our CSV file in GeoJSON from the latitude and longitude columns.

Transform your geospatial data to a CSV using GDALįirst you need to install GDAL if you don’t have it.

This process is very similar to the Python route but using the native tools within AWS.

DATA TYPES REDSHIFT FULL

You can check out the full post here and get access to the code here. The code includes a function to read the data types from Fiona and create the table which is required to execute the COPY command.Import the data into Redshift using the Redshift Data API.Create a CSV file with EWKB geometries using Fiona and Shapely.This post from our own Borja Muñoz outlines a step by step approach to transforming the data, loading the data to S3, and then using the Redshift Data API and the boto3 Python package to load your data.
