This article is about unstable sorting algorithm. For compatibility, see a specific version number.

## A stable sorting algorithm works by giving each row a minimum length, and the maximum of all the row’s columns in this minimum length.

The result of a stable sorting algorithm is a sorted column, but the result of an unbalanced sorting algorithm results in the entire row not being sorted. This is often due to differences in column types (e.g. a small row is less sorted than a large row).

This condition can be used to achieve an optimal sorting if the output is in the form of an empty string with the same column as the rest of the columns.

The following table lists sorting condition results by column type to ensure you never get unbalanced sorting.

Columns with a minimum 1,000 columns are sorted according to the sorting algorithm used:

Table 1. Alias for sorting errors (redir.csv) Alias for sorting error (redithreads.csv) column 1 – 1 000 rows – 1 : 1 : 1 column 2 – 4 : 2 : – – column 3 – 7 : – – column 4 – 22 : – – column 5 – 4 : – – column

Sorting errors using different sorting methods

For sorting errors where two sets of rows are not sorted, a combination of different sorting methods is used and a minimum amount of rows is passed to a key.

The sorting algorithm is implemented with key_stored to guarantee
