Use ARDELRANGE to empty every occupied slot inside one or more inclusive index ranges. Several ranges can be given in one call and the reply is the total number of values removed across all of them, which makes it the efficient way to trim a window of an array without listing every index. As with ARDEL, deleting leaves holes instead of shifting values, and removing the last remaining value deletes the key. Ranges that overlap are allowed; a value is counted once, when it is removed. See the array command overview for the data model these commands share.

Syntax

Arguments

Important points

  • The number of arguments after the key must be even; an odd count returns a wrong number of arguments error.
  • Each range is applied in the order given, and the reply is the total across all of them.

Response

The reply reports the result of the operation. Error replies have the same shape in RESP2 and RESP3 and are surfaced as exceptions by the SDKs below.
Client libraries often decode bulk strings, maps, sets, and numeric strings into language-native values. The table describes the Redis wire reply.

Examples

TCP examples use the TLS REDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
