I look at the source code intablet_sink.cpp, I foud the checker which check maxValue and minValue of decimal if (dec_val > _max_decimalv2_val[i] || dec_val < _min_decimalv2_val[i]).

And I look at the source code in decimalv2_value.cpp, I found the max value of integer part is 999999999999999999 and the max value of fractional part is 999999999 .

But in the document define data type of DECIMAL is DECIMAL(M[,D]) 高精度定点数，M代表一共有多少个有效数字(precision)，D代表小数点后最多有多少数字(scale) M的范围是[1,27], D的范围[1, 9], 另外，M必须要大于等于D的取值。默认的D取值为0
