# Save the DB on disk:
#
# save <seconds> <changes>
#
# Will save the DB if both the given number of seconds and
# the given number of write operations against the DB occurred.
#
# In the example below the behaviour will be to save:
# after 900 sec (15 min) if at least 1 key changed
# after 300 sec (5 min) if at least 10 keys changed
# after 60 sec if at least 10000 keys changed
#
# Note: you can disable saving at all commenting all the
# "save" lines.
save 900 1
save 300 10
save 60 10000

18. Nest
Object-oriented Keys for Redis
github.com/soveran/nest
• Creates a Redis connection by default
• Calls to_s for key representation
• Really simple code / hack it for your needs
Tuesday, May 22, 2012
34. Testing Tips
•Don’t bother mocking out Redis
•Select a different database number
so you don’t clobber anything
•Redis.current.flushdb is your
friend
