Summary: Vectorization: Closed range fast-path for Fast Long
hashset
Key: HIVE-20501
URL: https://issues.apache.org/jira/browse/HIVE-20501
Project: Hive
Issue Type: Improvement
Reporter: Gopal V
In scenarios where the surrogate keys are entirely contiguous, the cache can
offer a fast-path for [min,max], without a further lookup in the hashtable.
{code}
hive> select min(c_customer_sk), max(c_customer_sk), max(c_customer_sk) -
min(c_customer_sk), count(1) from customer;
1 65000000 64999999 65000000
