Leverage TwoLevelCache for resiliency
TwoLevelCache might not have a significant impact on latency in most cases but it would have on resiliency.
For example if we have a TwoLevelCache setup with the first level as a local in memory cache and the second layer using Redis or Memcached the cache could have a flag to ignore failures on the second level, so as long as the first level is available the app would remain functional.
This should probably be false by default and when set to true it would still log some warning, or maybe it can throw some custom exception that can be handled by the app and the developer can decide to ignore it or not.
KeyError when using 8.x
Hi, I was trying to update my dependencies and started getting a KeyError when using any 8.x version, I was using cachetools~=5.3.0 and CacheToolsUtils~=6.0; tried to update to cachetools~=5.3.2 and CacheToolsUtils~=8.2 and started getting errors, the same code works fine with cachetools~=5.3.2 and CacheToolsUtils~=7.0.
I'm using the TwoLevelCache with a local map and Redis and the same error occurs regardless of setting resilient to True or not.
The error details, on the first call to the cached method (using the decorator):
Traceback (most recent call last):
File "/usr/lib/python3.10/site-packages/cachetools/__init__.py", line 68, in __getitem__
return self.__data[key]
KeyError: ('ca07b064874e1b243a8edab3ff97e9e32d1420dee27ca974fbf92a36e94dac72',)
During handling of the above exception, another exception occurred:

The `FIXME` is right, get, pop, setdefault should use the _key function
