How To Create a Lever Hiring Python Pipeline with PyAirbyte

Extracting and managing data from Lever Hiring can pose significant challenges, including dealing with complex API integrations, handling rate limits, and ensuring data is consistently up-to-date. PyAirbyte offers a solution to these obstacles by simplifying the data extraction process.

With its easy setup, flexible configuration, and ability to perform incremental updates, PyAirbyte reduces the complexity and maintenance burden associated with traditional data pipelines. This makes it an efficient tool for leveraging Lever Hiring data for analysis, reporting, and AI applications.

Traditional Methods for Creating Lever Hiring Data Pipelines

Traditionally, data teams have relied on custom Python scripts to extract data from various sources, including Lever Hiring, a popular applicant tracking system. These scripts are written to interact directly with Lever's API, fetching data that can include candidate details, job postings, application statuses, and more. The script might parse this data into a structured format before loading it into a data warehouse or database for further analysis and reporting.

Pain Points in Extracting Data from Lever Hiring

While custom scripts offer flexibility, they come with several pain points specific to extracting data from Lever Hiring:

1. Complex API Handling: Lever's API, like many others, imposes rate limits and requires authentication. Developers need to write additional code to handle these aspects, complicating the script.
2. Data Schema Changes: Lever Hiring might update its data schema or API endpoints without warning. Such changes can break existing scripts, requiring immediate attention and updates to ensure data flows are not interrupted.
3. Error Handling: Adequate error handling within scripts is crucial. Without it, failed data extraction attempts might go unnoticed, leading to data discrepancies and integrity issues.
4. Pagination and Incremental Loads: Efficiently handling large volumes of data often requires implementing pagination and incremental data loading logic. This adds complexity to the scripts, especially when trying to optimize for performance and minimize API calls.

Impact on Data Pipeline Efficiency and Maintenance

These pain points have a significant impact on the efficiency and maintenance of data pipelines:

• Increased Maintenance Effort: Keeping scripts updated with API changes, and schema adjustments require constant vigilance and quick responses from the data engineering team. This can divert valuable resources from other projects and tasks.
• Scalability Issues: As the company grows, the volume of data to be processed increases. Handwritten scripts that are not designed with scalability in mind might struggle to handle larger datasets efficiently, leading to performance bottlenecks.
• Reliability Concerns: The risk of script failure due to unhandled errors or API changes can lead to gaps in data, affecting downstream processes and decision-making based on this data.
• Resource Intensive: Developing and maintaining these scripts requires significant developer time and expertise. Additionally, managing the infrastructure for running these scripts securely and at scale can further increase costs.

In summary, while custom Python scripts provide a direct route to extract data from Lever Hiring, they introduce challenges related to complexity, scalability, reliability, and ongoing maintenance. Each of these can detract from the efficiency of data pipelines, ultimately impacting the organization's ability to leverage this data effectively for hiring insights and analytics.

Implementing a Python Data Pipeline for Lever Hiring with PyAirbyte

Installation

First, ensure you have PyAirbyte installed in your Python environment. PyAirbyte is a Python package that facilitates the interaction with Airbyte, an open-source data integration platform. To install PyAirbyte, use the following command:

pip install airbyte


Setting Up the Source Connector

After installing PyAirbyte, you start by importing the Airbyte module in your Python script. This module provides various functionalities to interact with Airbyte and set up data pipelines:

import airbyte as ab


Next, you define and configure the source connector for Lever Hiring. This step involves specifying the unique identifier for the Lever Hiring source (source-lever-hiring), indicating to PyAirbyte to install the connector if it's missing, and providing the necessary configuration parameters such as the start date, environment, and authentication credentials:

source = ab.get_source(
   "source-lever-hiring",
   install_if_missing=True,
   config={
       "start_date": "2021-03-01T00:00:00Z",
       "environment": "Sandbox",
       "credentials": {
           "auth_type": "Client",
           "client_id": "your_client_id_here",
           "client_secret": "your_client_secret_here",
           "refresh_token": "your_refresh_token_here"
       }
   }
)


In this snippet, start_date indicates the earliest date from which data should be fetched. The environment could be either Sandbox for testing or another environment as per your setup. The credentials section must be filled with your Lever Hiring API client credentials.

Verifying and Listing Streams

After configuring the source, it's good practice to verify the provided configuration and credentials to ensure everything is set up correctly:

source.check()


Then, you can list all available streams (data types, such as candidates or applications, that can be imported from Lever Hiring) for the configured source connector:

source.get_available_streams()


Selecting Streams and Reading Data

To proceed with data extraction, you first select the streams you're interested in. If you wish to import all available data, use the select_all_streams() method:

source.select_all_streams()


Alternatively, if you prefer to select specific streams only, you would use the select_streams() method, not shown here.

Next, you set up a cache to temporarily store the data read from Lever Hiring. Here, the script utilizes the default local cache provided by PyAirbyte, which is DuckDB, but you could configure it to use other databases such as Postgres, Snowflake, or BigQuery:

cache = ab.get_default_cache()
result = source.read(cache=cache)


Transferring Data to a DataFrame

Finally, to utilize this data within a Python environment for analysis, you can transfer data from a specific stream of interest into a pandas DataFrame. Replace "your_stream" with the actual name of the stream you're interested in:

df = cache["your_stream"].to_pandas()


This step enables you to perform data analysis, visualization, or further processing within Python, leveraging the powerful pandas library for data manipulation.

This entire process illustrates how PyAirbyte can be used to set up a robust data pipeline from Lever Hiring into a Python environment, simplifying data extraction and loading operations and making the data readily available for analysis and reporting.
