Work Description: ramesh0201 commented on issue #880: HIVE-22515 Support
cast to decimal64 in Vectorization
URL: https://github.com/apache/hive/pull/880#issuecomment-579036627
Whenever we have an expression like `long column <compare/arithmetic
operator> decimal column`, we always cast long to decimal even if the decimal
column can be represented as decimal64. This prevents us from using Deicmal64
class of operations that will be faster than the equivalent Decimal class of
operations. This Jira will implements cast from long to decimal64 that can help
in more optimizations in the decimal64 operations.
