Scaling Data Science At Your Organization - Part 2

November 2021

Summary

Expanding data science capacities in organizations demands stable infrastructure and strategic tools. The second session of our webinar series focused on the vital elements needed for uplifting data science efforts. Infrastructure is the supportive framework that enables the flow of data from raw data collection to insightful analysis. The discussion highlighted the importance of data access, data processing, and the use of tools to simplify workflows. Key tools like Apache Airflow, Metaflow, and MLflow were spotlighted for their roles in managing data pipelines and machine learning workflows. The significance of data discovery tools like Amundsen and the need to match tools with organizational needs were also stressed. Ultimately, the right mix of infrastructure and tools can enable organizations to be more data-focused, ensuring data literacy across all levels.

Key Takeaways:

Infrastructure is vital for moving data from collection to insight.
Data pipelining tools like Apache Airflow simplify task execution.
Data discovery tools facilitate easy access to relevant datasets.
Custom tools can simplify repetitive tasks and enhance efficiency.
Matching tools with user skills enhances data-focused decision-making.

Infrastructure and Data Flow

Data infrastructure acts as the basis of an organization's ability to utilize data science on a large scale. It includes the collection, storage, processing, and analysis of data. A strong infrastructure ensures that data can be easily accessed and used across the organization. The AI hierarchy of needs is a useful framework for understan ...

ding this flow, with data collection at the base and advanced analytics at the peak. As Ramnath Vaidyanathan noted, "data infrastructure is the primary building block that allows data to move from the bottom of the pyramid all the way to the top." A centralized data warehouse, such as those offered by Google Cloud, AWS, or Microsoft Azure, acts as a single source of truth, facilitating efficient data processing and insight generation. By understanding and investing in proper infrastructure, companies can ensure that data is not only accessible but also actionable.

Data Pipelining Tools

Efficient data pipelining tools are key for managing complex data workflows. These tools help automate the sequence of tasks needed to process and analyze data. Apache Airflow, a significant player in this space, lets organizations schedule and monitor workflows efficiently. As described in the webinar, Airflow is used extensively at DataCamp, where it organizes data tasks from collection to reporting. The tool is particularly useful because it handles dependencies and optimizes task execution, ensuring that data is processed in the correct order. For machine learning workflows, Metaflow and MLflow offer specialized capabilities, allowing for easy integration of data processing with model training and deployment. Choosing the right pipelining tool is essential for organizations aiming to expand their data capabilities effectively.

Tools for Data Discovery

Data discovery tools play an essential role in enabling users to find and utilize data efficiently. These tools act like search engines within an organization, helping users locate datasets relevant to their needs. Amundsen, developed by Lyft, is an example of a tool that offers stable data discovery capabilities, including features like data profiling and lineage tracking. These tools are vital for ensuring that team members can access and trust the data they need without extensive knowledge of the underlying infrastructure. "We need to think these tools through in a very clear way," stressed Vaidyanathan, highlighting the need for tools that cater to diverse user preferences and skill levels. By investing in comprehensive data discovery tools, organizations can democratize data access and drive more informed decision-making.

Custom Tooling for Efficiency

Custom tools can significantly enhance efficiency by automating repetitive tasks and standardizing processes. These tools are often built on top of existing data infrastructure to address specific organizational needs. For instance, DataCamp has developed internal tools like DataCamp R and DCmetrics to simplify data access and metric tracking, respectively. Such tools reduce the time and effort required for data scientists to perform routine tasks, allowing them to focus on more complex analyses. Similarly, companies like Airbnb have developed tools to automate A/B testing analysis, saving time and ensuring consistency. As the webinar stressed, investing in custom tools, even for small organizations, can provide long-term benefits by simplifying scalability and improving overall productivity.
