A Datalake stores a large amount of structured and unstructured information. The data is typically stored in files organized into folders based on timestamps, in formats such as Parquet and Avro.

Datalakes are low-cost and flexible and provide the following data warehouse-like properties:
  • Efficient data access and management
  • Guaranteed ACID transactions
  • Schema evolution
  • Partition evolution
  • Time travel

An open table format provides the preceding characteristics by overlaying a table format on groups of files in a Datalake, allowing you to treat those groups as a single table.
