HSETEX key [FNX | FXX] [EX seconds | PX milliseconds | EXAT unix-time-seconds | PXAT unix-time-milliseconds | KEEPTTL] FIELDS numfields field value [field value ...]

The HSETEX command allows setting the value of one or more fields of a given hash key, and optionally manipulating their expiration time. The command will return 1 in case all provided fields have been set or 0 in case FNX or FXX were provided and non of the specified fields were set. Without providing any optional flags, this command behaves exactly like a normal valkey-hset(7) HSET command.

The HSETEX command supports a set of options that modify its behavior:

• FNX — Only set the fields if none of them already exist.
• FXX — Only set the fields if all of them already exist.
• EX seconds — Set the specified expiration time in seconds.
• PX milliseconds — Set the specified expiration time in milliseconds.
• EXAT unix-time-seconds — Set the specified Unix time in seconds for when the fields will expire.
• PXAT unix-time-milliseconds — Set the specified Unix time in milliseconds at which the fields will expire.
• KEEPTTL — Retain the TTL associated with the fields.

Note for the following:

1. The EX, PX, EXAT, PXAT, and KEEPTTL options are mutually exclusive.
2. Setting a value on a volatile hash field (A field which has an assigned expiration time) will remove the expiration for that field.
3. Providing `0' expiration TTL via EX or PX optional arguments will result in the specified fields immediately expiring and being removed from the hash.
4. Providing past expiration time via EXAT or PXAT optional arguments will result in the specified fields immediately expiring and being removed from the hash.

Add 3 new items without expiration time to a `myhash'

(integer) 1

Unsuccessful attempt setting expiration time on EXISTING fields

127.0.0.1:6379> HSETEX myhash FNX EX 10 FIELDS 2 f2 v2 f3 v3
(integer) 0

Successful attempt setting expiration time on EXISTING fields

Verify hash fields expiration time:

127.0.0.1:6379> HTTL myhash FIELDS 3 f1 f2 f3
1) (integer) -1
2) (integer) 8
3) (integer) 8

Override all hash items will also persist the fields

127.0.0.1:6379> HSETEX myhash FIELDS 3 f1 v1 f2 v2 f3 v3
(integer) 1
127.0.0.1:6379> HTTL myhash FIELDS 3 f1 f2 f3
1) (integer) -1
2) (integer) -1
3) (integer) -1

Setting expiration time in the past will remove all the elements in the hash:

127.0.0.1:6379> HSETEX EX 0 myhash FIELDS 3 f1 v1 f2 v2 f3 v3
(integer) 1
127.0.0.1:6379> HTTL myhash FIELDS 3 f1 f2 f3
1) (integer) -2
2) (integer) -2
3) (integer) -2
127.0.0.1:6379> HLEN myhash
(integer) 0
127.0.0.1:6379> EXISTS myhash
(integer) 0
