Data processing
The data processing functionality of a data lake encompasses the frameworks and compute resources necessary for various data processing tasks, such as data correction, transformation, merging, splitting, and ML feature engineering. Common data processing frameworks include Python shell scripts and Apache Spark. The essential requirements for data processing technology are as follows:
- Integration and compatibility with the underlying storage technology: The ability to seamlessly work with the native storage system simplifies data access and movement between the storage and processing layers.
- Integration with the data catalog: The capability to interact with the data catalog's metastore for querying databases and tables within the catalog.
- Scalability: The capacity to scale compute resources up or down to accommodate changing data volumes and processing velocity requirements.
- Language and framework support: Support for popular data processing libraries and frameworks...
