Redis SortedSet DataType

  • Mix between Set and Hash data structure
  • Are implemented via a dual port data structure containing both a skip list and a hash table
  • Adding elements and retrieving sorted elements is extremely fast

    • multiple fields called members and
    • their numerical values called scores
  • All the members are always unqiue, non repetative strings
