🏷️ Labels: Data Processing, Dask, Pandas, Optimization, Census Data
📂 Project: Dev
⭐ Priority: MEDIUM

Session Goal:

The primary objective of this session was to optimize the processing of census data using Dask and Pandas, focusing on efficient data loading, filtering, and merging operations.

Key Activities:

  • Data Loading and Filtering: Demonstrated loading and filtering of census data from CSV files using Dask, specifically targeting housing, households, and individuals datasets.
  • Data Processing with Dask: Implemented a workflow using Dask for handling large datasets, including merging, sampling, and computing ratios based on population projections.
  • Code Correction and Optimization: Corrected and optimized Python code for processing census data, emphasizing the use of the compute() function and optimizing data merging processes to enhance performance.
  • Progress Tracking: Utilized a progress bar to track data sampling and merging operations, ensuring efficient execution.

Achievements:

  • Successfully loaded and filtered census data using Dask and Pandas.
  • Optimized data processing workflows by implementing the compute() function and reducing unnecessary computations.
  • Enhanced code efficiency and performance in data merging tasks.

Pending Tasks:

  • Further optimization of data processing workflows to ensure scalability and efficiency.
  • Exploration of additional data processing techniques to improve performance further.
