Hash Join V2 - 2024.2 English

Hash Join V2 resides in the L1/benchmarks/hash_join_v2 directory. This benchmark tests the performance of hashJoinMPU from hash_join_v2.hpp with the following query:

SELECT
       SUM(l_extendedprice * (1 - l_discount)) as revenue
FROM
       Orders,
       Lineitem
WHERE
       l_orderkey = o_orderkey
;

Here, Orders is a self-made table filled with random data, which contains a column named o_orderkey. Lineitem is also a table, which contains three columns named l_orderkey, l_extendedprice, and l_discount.
