redis SORT command syntax
Function:Return or save the sorted elements in a given list, set, or ordered set key. Sorting defaults to numbers as objects, values are interpreted as double-precision floating point numbers and then compared.
Syntax:SORT key [BY pattern] [LIMIT offset count] [GET pattern [GET pattern ...]] [ASC | DESC] [ALPHA] [STORE destination]
Available versions:>= 1.0.0
Time complexity:O(N M*log(M)), N is to be sorted The number of elements in the list or set, M is the number of elements to be returned. If you just use the GET option of the SORT command to obtain the data without sorting, the time complexity is O(N).
Return:Without using the STORE parameter, the sorted result in list form is returned. Use the STORE parameter to return the number of elements in the sorted result.
