Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

JSON.DEL

Deletes the JSON values at the path in a document key. If the path is the root, it is equivalent to deleting the key from Valkey or Redis OSS.

Syntax

JSON.DEL <key> [path]

  • key (required) – A Valkey or Redis OSS key of JSON document type.

  • path (optional) – A JSON path. Defaults to the root if not provided.

Return

  • Number of elements deleted.

  • 0 if the Valkey or Redis OSS key does not exist.

  • 0 if the JSON path is invalid or does not exist.

Examples

Enhanced path syntax:

127.0.0.1:6379> JSON.SET k1 . '{"a":{}, "b":{"a":1}, "c":{"a":1, "b":2}, "d":{"a":1, "b":2, "c":3}, "e": [1,2,3,4,5]}'
OK
127.0.0.1:6379> JSON.DEL k1 $.d.*
(integer) 3
127.0.0.1:6379> JSOn.GET k1
"{\"a\":{},\"b\":{\"a\":1},\"c\":{\"a\":1,\"b\":2},\"d\":{},\"e\":[1,2,3,4,5]}"
127.0.0.1:6379> JSON.DEL k1 $.e[*]
(integer) 5
127.0.0.1:6379> JSOn.GET k1
"{\"a\":{},\"b\":{\"a\":1},\"c\":{\"a\":1,\"b\":2},\"d\":{},\"e\":[]}"

Restricted path syntax:

127.0.0.1:6379> JSON.SET k1 . '{"a":{}, "b":{"a":1}, "c":{"a":1, "b":2}, "d":{"a":1, "b":2, "c":3}, "e": [1,2,3,4,5]}'
OK
127.0.0.1:6379> JSON.DEL k1 .d.*
(integer) 3
127.0.0.1:6379> JSON.GET k1
"{\"a\":{},\"b\":{\"a\":1},\"c\":{\"a\":1,\"b\":2},\"d\":{},\"e\":[1,2,3,4,5]}"
127.0.0.1:6379> JSON.DEL k1 .e[*]
(integer) 5
127.0.0.1:6379> JSON.GET k1
"{\"a\":{},\"b\":{\"a\":1},\"c\":{\"a\":1,\"b\":2},\"d\":{},\"e\":[]}"
