Determine if a hash field exists (http://redis.io/commands/hexists). Since Redis 2.0.0

Sets expiration for hash fields using relative time to expire in seconds (https://redis.io/commands/hexpire).

O(N) where N is the number of specified fields.

Set an expiration (TTL or time to live) on one or more fields of a given hash key. You must specify at least one field. Field(s) will automatically be deleted from the hash key when their TTLs expire.

Field expirations will only be cleared by commands that delete or overwrite the contents of the hash fields, including HDEL and HSET commands. This means that all the operations that conceptually alter the value stored at a hash key's field without replacing it with a new one will leave the TTL untouched.

You can clear the TTL using the hpersist command, which turns the hash field back into a persistent field.

Note that calling hexpirehpexpire with a zero TTL or hexpireathpexpireat with a time in the past will result in the hash field being deleted.
