Prefer SET with the GET argument in new code: SET <key> <value> GET.
Use GETSET to set a new value and get the previous one in a single atomic step. The reply is the old value, or null when the key did not exist. Note that the key’s time to live is discarded, so a key with an expiration becomes permanent when written this way. The classic use is resetting a counter while reading it, where the atomicity guarantees nothing is counted twice. SET with the GET option does the same thing and can additionally set or keep an expiration in the same call.

Arguments

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.
