Panagiotis Garefalakis updated HIVE-25146:
------------------------------------------
Description:
JMH tests for parallel HT load, configuration parameters include
LOAD_THREADS_NUM, ROWS_NUM and JOIN_TYPE.
A single thread simulates the default load behaviour while ROWS_NUM < 1M will
default to a single thread for simplicity.
Higher number of threads >=2 evaluates the benefit of parallel loading of the
HT.
was:As the title suggests, add some benchmarks for Parallel HT construction
feature
