Aditya Manthramurthy 4aa9ee153b Fix S3 Select request XML parsing (#7202) 2019-02-06 13:25:52 -08:00
Aditya Manthramurthy 2786055df4 Add new SQL parser to support S3 Select syntax (#7102)
- New parser written from scratch, allows easier and complete parsing
  of the full S3 Select SQL syntax. Parser definition is directly
  provided by the AST defined for the SQL grammar.

- Bring support to parse and interpret SQL involving JSON path
  expressions; evaluation of JSON path expressions will be
  subsequently added.

- Bring automatic type inference and conversion for untyped
  values (e.g. CSV data).
