> Yes. But, luckily, in this case the functions should already exist: https://gist.github.com/westonpace/a45738e5a356324d410cba2c2713b1fd No, the compare Functions currently don't support comparing between single elements in array. Like `a_array->data()->GetValues<CType>(a_indice) > b_array->data()-><Ctype>GetValues(b_indice)`. These Function can be used to compare two array entirely. But merge sort only need to compare the min/max keys between different arrays, comparing the entire arrays is too costly. -- This is an automated message from the Apache Git Service.
