HINCRBY to add an integer to the number stored in a hash field and get the result.
A missing field, or a missing key, is treated as 0, so the first call creates the hash and the field. The increment may be negative to count down. The stored value must be the string form of a 64-bit signed integer; anything else returns an error, as does an operation that would overflow the range.
Reading, adding, and writing back happen as one atomic step, so concurrent callers each receive a distinct result and no update is lost. That makes hashes a compact way to keep many related counters, such as per-status counts for one entity, under a single key.
Syntax
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 TLSREDIS_URL from the Upstash console. REST examples use UPSTASH_REDIS_REST_URL and UPSTASH_REDIS_REST_TOKEN.
