Description

The SCAN command and the closely related commands SSCAN, HSCAN and ZSCAN are used in order to incrementally iterate over a collection of elements.

  • SCAN iterates the set of keys in the currently selected Redis database.
  • SSCAN iterates elements of Sets types.
  • HSCAN iterates fields of Hash types and their associated values.
  • ZSCAN iterates elements of Sorted Set types and their associated scores.
