Note find_olap_engine has a similar issue too.


        int64_t int_value = *(int64_t*)(data);
        int32_t frac_value = *(int32_t*)((char*)data + sizeof(int64_t));
Should be:
        int64_t int_value;
        memcpy(&int_value, data, sizeof(int_value));
        int32_t frac_value;
        memcpy(&frac_value, (char*)data + sizeof(int64_t), sizeof(frac_value));
