Fivetran is a cloud-centric solution aimed at automating the extraction, transformation, and loading (ETL) of data from diverse sources into a data warehouse. It is renowned for its user-friendly interface and extensive connector support, allowing for seamless integration with numerous data sources via distinct connectors that operate independently, tailored to the specific needs of each source.

Features Summary:

Fivetran encompasses a wide array of features across categories such as data movement, transformations, security, governance, and management. It supports various data sources, including SaaS applications, databases, streaming data, and custom connectors. For data storage, it accommodates both data lakes and warehouses. The platform is also compatible with partner technologies like AWS, Google BigQuery, Azure, and Snowflake. Key advantages include:

• Over 400 fully managed connectors for varied data sources.
• Automated schema migrations and continuous data synchronization.
• A preferred choice for organizations seeking a low-maintenance solution.
• Support for both push and pull data models.

Architecture:

High-Level: Fivetran operates as a serverless, cloud-based platform, ensuring scalability and effortless maintenance.

Low-Level Components: This includes a connection manager, data processing units, and a scheduler. The connection manager manages links to various data sources, while data processing units handle ETL processes, and the scheduler orchestrates data synchronization tasks.

Code Example:

Fivetran provides multiple automation methods, including API services and Terraform providers. Below is a Python script that illustrates how to use the Fivetran API to create a new connector.

import requests

import json

import base64

api_key = "your_api_key"

api_secret = "your_api_secret"

connector_config = {

"service": "salesforce",

"group_id": "your_group_id",

"config": {

"api_token": "your_salesforce_api_token",

"api_secret": "your_salesforce_api_secret"

}

}

headers = {

"Authorization": "Basic " + base64.b64encode(f"{api_key}:{api_secret}".encode()).decode(),

"Content-Type": "application/json"

}

response = requests.post(api_url, headers=headers, data=json.dumps(connector_config))

print(response.json())

Section 1.2: Stitch Overview

Stitch is an ETL service that allows users to gather data from various sources into a single data warehouse. It prioritizes user-friendliness, efficiency, and reliability, integrating seamlessly with numerous databases and SaaS applications. Stitch is designed as a self-service ETL tool, balancing customization with simplicity.

Features Summary:

Stitch Advanced features include API access for account management, support for multiple destinations, custom notifications, and advanced scheduling options. It integrates with over 100 sources, supports incremental loading, and is favored for its combination of functionality and ease of use.

Architecture:

High-Level: Stitch utilizes a microservices architecture for modularity and flexibility.

Low-Level Components: It comprises source connectors (taps), destination connectors (targets), a processing layer, and a job scheduler.

Data Flow: Data is extracted from sources using taps, transformed in the processing layer, and then loaded into targets.

Code Example:

Though Stitch primarily features a user interface, it can also be operated via its API or a Python client. Below is an example of a Python 3 client setup:

pip install stitchclient

export STITCH_CLIENT_ID= your_stitch_client_id

export STITCH_TOKEN= your_stitch_import_token

export STITCH_REGION=us

from stitchclient.client import Client

with Client(

os.environ['STITCH_CLIENT_ID'],

os.environ['STITCH_TOKEN'],

os.environ['STITCH_REGION'],

callback_function=print,

) as client:

client.push({

'action': 'upsert',

'table_name': 'MY_TABLE',

'key_names': ['table_id'],

'sequence': 10,

'data': {

'id': 10,

'value': 'my_value',

},

}, 10)
