[PR] fix: DECIMAL type coercion losing fractions. (druid)

["gianm (via GitHub)" <gi...@apache.org>]

gianm opened a new pull request, #20456:
URL: https://github.com/apache/druid/pull/20456

   DECIMAL type coercion could lose fractions due to the least restrictive type of DECIMAL(19, 0) and DECIMAL(2, 1) being computed as DECIMAL(19, 0). This could arise with JSON_VALUE because JSON_VALUE with RETURNING DECIMAL uses the default precision of DECIMAL(19, 0).
   
   The behavior seems new since #19370, so may be connected to an underlying Calcite change. At any rate, this type system change on our end avoids the problem.
