Working with Large Datasets

Working with Large Datasets#

Large datasets create processing challenges

Loading Time

  • Reading from storage takes time

  • Parsing and validation add overhead

  • Multiple passes multiply delays

Memory Constraints

  • Dataset may not fit in RAM

  • Requires streaming or batching

  • Increases complexity

Additional Considerations#

  • Data preprocessing becomes a significant phase

  • May need specialized formats (HDF5, Parquet, Zarr)

  • Indexing strategies become critical

Indexing

Use technologies that enable fast lookup and retrieval without having to scan an entire dataset.
