Redis List commands

List is a sequence of ordered elements, for example 10, 5, 16, 20, 19 is a list. Redis lists are implemented as linked lists. Since lists in redis are implemented as linked list, adding elements to head/ tail of the list is faster, but accessing element using index is slow.

Redis provides number of commands to work with list.

Insert value into the list only if list exists
Insert all the specified values at the tail of the list

Removes and reurns the last element of the list
Returns elements of list for specified range
Removes first count occurrences of value from the list
Sets the list index with given value
Returns the element at specific index of the list
Returns the length of the list
Trim the list, so that it will contain only the specified range of elements specified
Insert the value into the list just before/after pivot value
