> Key: DRILL-3134
> URL: https://issues.apache.org/jira/browse/DRILL-3134
> Project: Apache Drill
> Issue Type: Bug
> Components: Documentation
> Reporter: Daniel Barclay (Drill)
> Assignee: Kristine Hahn
>
> On the the "Supported Data Types" page at
> http://drill.apache.org/docs/supported-data-types/, the first subsection
> (before the "Casting and Converting Data Types" subsection) doesn't include
> composite types (arrays and maps). Since that subsection seems to be
> intended to be the orientation to the set of data types that are available in
> Drill, it should include composite types as well as the atomic types it
> already includes.
> For those composite types, it should mention the key type-specific operations
> on those types (i.e., for arrays: array element references (SQL's <array
> element reference> construct, e.g., {{a[1]}}); for maps: the construct(s)
> that Drill provides for referring to the value for a given key, e.g.,
> {{m['k']}}). (It should probably also have links to the sections, pages, or
> subsections for the special functions for those types (e.g., KVGEN, FLATTEN).)
> (Note that although the text "SQL data types for query input" seems
> (depending the interpretation of "query input") to indicate that the section
> was conceived of to document the set of data types for which users can _give
> literal values_ in SQL queries, that apparent intent should be widened to the
> set of data types that users _deal with_ in queries.
> For example, even though users can't (yet) give a value of an array type in a
> query, they can deal with array values coming from data sources, e.g., by
> indexing the array value to get a specific element of each array value.)
