Hello,
I am using the uWSGI cache feature to reduce the number of DB queries. The flow
looks like this (code is written in Python):
request comes in:
value = cache_get(key)
if value:
return value
else:
value = db_query(...)
cache_set(key, pickle.dumps(value), 60)
It works well for few minutes. After that, it calls cache_set for some keys
more than once every 60 second (once a second or more frequently). I would
expect cache_set to not be called more than once every 60 seconds because I
pass expires=60 to cache_set.
cache_get doesn't return anything even if cache_set succeeds (return value is
True). This is what worries me.
Let me know if you need more details.
