----------------------------------------
Summary: [C++] Add DecimalType support to JSON parser
Key: ARROW-4700
URL: https://issues.apache.org/jira/browse/ARROW-4700
Project: Apache Arrow
Issue Type: New Feature
Reporter: Benjamin Kietzman
Assignee: Benjamin Kietzman
This should be simple to add, since decimals can already be parsed from
strings. Decimals will be represented in JSON as strings. If a decimal with
different precision or scale is parsed from the string, should there be any
acceptable conversions? (for example, if the column is of type {{decimal(5,
2)}} should {{"12.3"}} be an error or equivalent to {{"012.30"}}?)
