The document discusses smart SQL processing for databases, Hadoop and beyond. It describes how Oracle teaches its database about Hadoop by publishing Hadoop metadata like SerDe, RecordReader and InputFormat information to Oracle's catalog. This allows SQL queries to be executed on Hadoop data. However, directly sending SQL queries to Hadoop data nodes presents bottlenecks, so the document discusses how Oracle makes SQL processing smarter by applying techniques like smart scan, storage indexing and caching utilized in Oracle Exadata to minimize data movement and improve performance.
