Issue Number: close #xxx
when cal array hash, elem size is not need to seed hash
hash = HashUtil::zlib_crc_hash(reinterpret_cast<const char*>(&elem_size),
sizeof(elem_size), hash);
but we need to be care [[], [1]] vs [[1], []], when array nested array , and nested array is empty, we should make hash seed to
make difference
2. use range for one hash value to avoid virtual function call in loop.
which double the performance. I make it in ut
column: array[int64]
50 rows , and single array has 10w elements
