The HGETEX command returns the value of one or more fields of a given hash key, and optionally manipulates their expiration time. The command will return an array in the size of the number of requested fields. Without providing any optional flags, this command behaves exactly like a normal HMGET command.

Options

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

• 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 at which the fields will expire, in seconds.
• PXAT unix-time-milliseconds — Set the specified Unix time at which the fields will expire, in milliseconds.
• PERSIST — Remove the expiration time associated with the fields.

Note for the following:

1. The EX, PX, EXAT, PXAT, and PERSIST options are mutually exclusive.
2. Providing '0' expiration TTL via EX or PX optional arguments will cause the specified fields to expire immediately and be removed from the hash.
3. Providing past expiration time via EXAT or PXAT optional arguments will cause the specified fields to expire immediately and be removed from the hash.
