Final answer:
The ORC file format has advantages such as efficient compression, support from multiple I/O engines, and exploitation of advanced features by Big SQL.
Step-by-step explanation:
An advantage of the ORC file format is efficient compression. ORC files use columnar storage, which allows for better compression because similar data is stored together. This reduces the storage space needed and improves query performance.
Another advantage is that ORC files are supported by multiple I/O engines. This means that you can use different tools and frameworks to read and write ORC files, making it more versatile and accessible.
Additionally, Big SQL can exploit advanced features of the ORC file format. Big SQL, which is a SQL engine for Hadoop, can take advantage of features like predicate pushdown and stripe level filtering in ORC files, which can improve query performance.
