Hi,
What's a good way to use a simple dictionary as a cache in twisted
framework?
Basically, I have this callback chain where I ultimately make a rest call
(in non-blocking way using treq) to fetch some data. But before I make the
call, I am using a dictionary to see if the value is available or not.
But, I have noticed that the event loop gets pretty busy(sometimes, things
get stuck and twisted server stops) as soon as I add this logic.. Which is
pretty much
@defer.inlinecallbacks
def fetch(key):
if key in cache:
return cache[key]
# else call back to treq to fetch value
cache[key] = value
return value
This dict can grow to around 50k.. What's a good way to solve this issue?
