Redis | redis-cli INFO / avg_ttl value

Question

When I run the command redis-cli INFO, one of the returned values indicates the avg_ttl. I'm unsure what unit of time this is represented in?

Example:

# Keyspace

db0:keys=706818,expires=228745,avg_ttl=1521990750

Answer 1

What do these commands return:

• the TTL - seconds
• PTTL - milliseconds
• avg_ttl - milliseconds

Also, note that the average value avg_ttl is an estimate using the random check of keys
