-Advanced types such as generic types, composite types (e.g. POJOs or
Tuples), and arrays can be fields of a row. Generic types and arrays are
treated as a black box within Table API and SQL yet. Composite types, however,
are fully supported types where fields of a composite type can be accessed
using the `.get()` operator in Table API and dot operator (e.g.
`MyTable.pojoColumn.myField`) in SQL. Composite types can also be flattened
using `.flatten()` in Table API or `MyTable.pojoColumn.*` in SQL.
