-----------------------------------------
Summary: [Gandiva] Add overflow checks for decimals
Key: ARROW-4570
URL: https://issues.apache.org/jira/browse/ARROW-4570
Project: Apache Arrow
Issue Type: Bug
Reporter: Pindikura Ravindra
Assignee: Pindikura Ravindra
For decimals, overflows can occur at two places :
# input array can have values that are outside the bound (eg. > 38 digits)
# When an operation can result in overflows. eg. add of two decimals of (38,
6) can result in an overflow, if the input numbers are very large.
In both the above cases, just verifying that an overflow occurred can be a perf
overhead. We should do this based on a conf variable.
