Method 2: Using Custom Code to Move Data from Klaviyo to Snowflake

This method of connecting Klaviyo to Snowflake would be time-consuming and tedious to implement. Users will have to write custom codes to enable Klaviyo to Snowflake migration. This method is suitable for users with a technical background.

You use an indirect method here to connect Klaviyo to Snowflake, first you migrate Klaviyo to Redshift and Redshift to Snowflake.

Klaviyo to Redshift

This is the first step to connecting Klaviyo to Snowflake. Follow the given steps to connect Klaviyo to Redshift:

Getting Data out of Klaviyo

  • Developers can access data on metrics, profiles, lists, campaigns, and templates using Klaviyo’s REST APIs. You can refine the information returned by using two to seven optional parameters in each of these APIs. A simple call to the Klaviyo Metrics API to retrieve data, for example, would look like this:
GET https://a.klaviyo.com/api/v1/metrics
  • As a response, the GET request returns a JSON object containing all of the fields from the specified dataset. For any given record, all fields might not be available. The JSON may appear as follows:
  "end": 1,
  "object": "$list",
  "page_size": 50,
  "start": 0,
  "total": 2,
  "data": [
      "updated": "2017-11-03 17:28:09",
      "name": "Active on Site",
      "created": "2017-11-03 17:28:09",
      "object": "metric",
      "id": "3vtCwa",
      "integration": {
        "category": "API",
        "object": "integration",
        "id": "4qYGmQ",
        "name": "API"
      "updated": "2017-11-03 20:54:40",
      "name": "Added integration",
      "created": "2017-11-03 20:54:40",
      "object": "metric",
      "id": "8qYK7L",
      "integration": {
        "category": "API",
        "object": "integration",
        "id": "4qYGmQ",
        "name": "API"

Loading Data into Redshift

You can use Redshift’s CREATE TABLE statement to define a table that will receive all of the data once you’ve identified the columns you want to insert.     

After you’ve created a table, you might want to migrate your data to Redshift by using INSERT statements to add data row by row. For inserting data one row at a time, Redshift isn’t designed for it. If you have a large amount of data to insert, save it to Amazon S3 and then load it into Redshift with the COPY command.

Keeping Klaviyo Data up to Date

  • It’s not a good idea to duplicate all of your data every time your records are updated. This would be a painfully slow and resource-intensive process.
  • Instead, identify key fields that your script can use to bookmark its progress through the data and return to as it searches for updated data. The best option for this is to use auto-incrementing fields like updated at or created at.
  • You can set up your script as a CRON job or a continuous loop to get new data as it appears in Klaviyo once you’ve added this functionality.
  • And, as with any code, you must maintain it once you’ve written it. You may need to change the script if Klaviyo changes its API, or if the API sends a field with a datatype your code doesn’t recognize. You will undoubtedly have to if your users require slightly different information.

Redshift to Snowflake

Database Objects Migration

The first step is, to begin with, database objects, which primarily include Schema, Table Structures, Views, etc. Instead of changing the object’s structure during migration, we should prefer to leave it alone because doing so would harm the entire migration process. Later, DB objects in Snowflake must be created with the same structure as those in Redshift.

Data Migration
  • Any project involving migration must include this activity. The first step is to determine the historical data sets for each table and how they can be migrated because the data volume will be quite high and we need to take this into account before beginning data migration activity. It is strongly advised to create separate batches for each table (based on the filter options like transaction date or any other audit columns) and migrate data in these batches rather than in one batch. 
  • After all historical data from all tables has been transferred to Snowflake, it will be relatively easy to move incremental data.
  • Using Redshift’s “Unload Command” to unload data into S3 and Snowflake’s “Copy Command” to load the data from S3 into Snowflake tables could be one solution. This may also display some errors caused by compatibility problems, which you have already experienced on several occasions. 
  • Another strategy involves using any data replication tool that supports Snowflake as a target, which can then be used to load raw data from the source system into Snowflake. ETL/ELT pipelines can fill facts, dimensions, and metrics tables on the Snowflake platform on top of this raw data.
Migrating Code to Snowflake 
  • Compared to the previous two steps, this one has fewer difficulties and restrictions. In theory, Redshift and Snowflake both support ANSI-SQL, but they use different formats for various items, such as the lack of DISTKEY, SORTKEY, and ENCODE concepts in Snowflake. 
  • There are many other examples of using functions, but one of the key distinctions between date functions is that Redshift’s GETDATE() and Snowflake’s CURRENT TIMESTAMP() are both date functions. While JSON, AVRO, and PARQUET are semi-structured data types that can be supported by Snowflake’s “VARIANT” datatype, they cannot be directly stored in Redshift.
  • To match the JSON field names in Redshift, the target table must be created by examining the JSON source data. Without a set structure, we cannot import it directly. Only the first-level elements can be parsed into the target table by the COPY functions. 
  • As a result, the multi-level elements are loaded into a single column and treated as strings. Redshift provides JSON SQL functions that must be used to further parse the intricate, multi-level data structures or arrays of JSON files. When migrating code, one must be extremely cautious and convert the code to supported SQL syntax.

Data Comparison between Redshift & Snowflake

  • The final step in any migration project is to compare the data sets from the legacy and newly migrated platforms to make sure that everything was successfully migrated and that the output was accurate for the business. 
  • Given that you are moving from Redshift to Snowflake in this scenario, you must contrast the outcomes from the two systems. Data comparison between Redshift and Snowflake manually is a time-consuming and difficult task.
  • Therefore, you created a custom Python script solution to connect to each DB, run some crucial checks against both DBs (Redshift as the source and Snowflake as the target), and compare the results.
  • Some crucial checks include Record Counts, Data Type Comparisons, Metrics Comparisons in Fact Tables, DB Object Counts, Duplicate Checks, etc. A daily CRON job can be scheduled or automated to execute this solution.
