FLUSHDB to delete every key in the current database.
Since Upstash exposes a single logical database, this removes everything, exactly like FLUSHALL. ASYNC frees the memory in a background thread and SYNC frees it before replying.
The deletion is immediate and irreversible. It is a convenient way to reset a test database between runs, and it should never be reachable from application code that runs against production data.
Syntax
Arguments
Important points
- This command can expose administrative information or make a broad destructive change. Restrict it to trusted code paths.
- This operation can inspect a large part of the database. Prefer cursor-based scans where possible and avoid unbounded use on hot paths.
- This deletes the database contents. Test against a disposable database and require an explicit operator action in production tooling.
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 TLSREDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
