hi I know that data is written into disk with the style of column-store if I enable doc-values for certain field. But I don't understand why sorting with docvalues doesn't increase the load of jvm. whatever sorting algorithm , data would be loaded into jvm to sort. This should be a high load for jvm when I sort all index , but no change for jvm in fact. How does lucene sort with docvalues ? Can sort algorithm work directly based on the file (Mmap) ?
