Use FUNCTION FLUSH to remove every function library from the database. This wipes all registered libraries and functions at once and cannot be undone, so it belongs in test setup and provisioning tooling rather than application code. ASYNC reclaims the memory in the background and SYNC reclaims it before the reply is sent.

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.
This command is not supported yet in upstash_redis.
