What is CSV Format in Data Lakes?
CSV (Comma-Separated Values) format is a simple and widely used file format that stores tabular data in plain text. In the context of data lakes, CSV format is used to store structured data in a central repository, allowing for easy access, sharing, and analysis of data.
How does CSV Format in Data Lakes work?
CSV format organizes data into rows and columns, with each row representing a record and each column representing a specific data attribute. The values in each row are separated by commas, hence the name "Comma-Separated Values". This format allows for easy parsing and processing of data using various tools and programming languages.
