Overview
- A view is another place source where data can be read, like streams and datasets.
- Therefore, views are readable anywhere a stream or dataset is readable (MapReduce/Spark program, flows, ETL)
- A view is a read-only view of a stream or dataset, with a specific read format (schema + format (csv, avro))
- If explore is enabled, then a Hive table will be created for each view
