Delta lake Vs Data lake in Databricks
Delta Lake is an open-source storage layer that sits on top of existing data lake storage, such as Azure Data Lake Store or Amazon S3. It provides a more robust and scalable alternative to traditional data lake storage, which is often prone to data inconsistencies and corruption.
Delta Lake offers the following benefits over traditional data lake storage:
๐ ACID transactions: Delta Lake supports ACID (Atomicity, Consistency, Isolation, Durability) transactions, which allow multiple users to read and write to the data lake concurrently without conflicting with each other. This helps ensure that data remains consistent and accurate, even when multiple users are writing to the same data.
๐ Versioning: Delta Lake automatically tracks changes to data and maintains a history of all changes, allowing you to roll back to a previous version if necessary.
๐ Time travel: Delta Lake allows you to query data as it existed at any point in time, making it easy to see how data has changed over time.
๐ Data quality checks: Delta Lake includes built-in data quality checks that can help detect and fix issues with data, such as null values or data type mismatches.
๐ฑ While Delta Lake is integrated into Databricks, a cloud-based data analytics platform that provides a collaborative workspace for data scientists and analysts to build, test, and deploy data pipelines and models. Delta Lake is natively supported in Databricks, making it easy to use and integrate with other Databricks features.
In summary, Delta Lake is a storage layer that sits on top of traditional data lake storage and provides additional features and capabilities for data management, such as ACID transactions, versioning, and data quality checks. It is natively supported in Databricks, making it easy to use and integrate with other Databricks features.
