Efficient data storage formats
Choosing the right storage format can significantly impact data loading and processing speed.
As an example, we can use Apache Parquet (https://parquet.apache.org/), a columnar storage format that’s particularly efficient for large datasets.
Here’s a table comparing different column formats and their characteristics for storing large language datasets:
