hive.cache.expr.evaluation
- Default Value:
true
- Added In: Hive 0.12.0 with HIVE-4209
- Bug Fix: Hive 0.14.0 with HIVE-7314 (expression caching doesn't work when using UDF inside another UDF or a Hive function)
If true, the evaluation result of a deterministic expression referenced twice or more will be cached. For example, in a filter condition like ".. where key + 10 > 10 or key + 10 = 0" the expression "key + 10" will be evaluated/cached once and reused for the following expression ("key + 10 = 0"). Currently, this is applied only to expressions in select or filter operators.
