HPEXPIRETIME - Upstash Documentation

Use HPEXPIRETIME to read the absolute expiration time of hash fields, as Unix timestamps in milliseconds.

The reply holds one value per requested field, in order: the timestamp at which it expires, -1 when the field exists but has no expiration, and -2 when the field or the key does not exist. It is the millisecond form of HEXPIRETIME and reports a deadline rather than the time left, which is the value to compare against a clock.

Syntax#

HPEXPIRETIME <key> FIELDS <numfields> <field> [<field> ...]

Arguments#

Argument	Required	Repeatable	Description
`<key>`	Yes	No	Redis key targeted by the command.
`FIELDS <numfields> <field> [<field> ...]`	Yes	No	Fields to target. Give the field count first, then that many field names.

Important points#

Negative integer replies are sentinel values, not durations or timestamps; see the response description for missing or persistent data.

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.

Protocol	Reply
RESP2	Array of expiration timestamps or negative integer status codes, one per field
RESP3	Array of expiration timestamps or negative integer status codes, one per field

Note

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.
