Method Details

[hide private]

set(self, key, value, max_age=None)

source code

Set a key/value pair unconditionally

Parameters:

key (str) - The key to store under
value (any) - The value to store (should be picklable)
max_age (int) - Maximum age in seconds. If omitted or None the default is applied.

Returns: bool

Stored successfully?

add(self, key, value, max_age=None)

source code

Set a key/value pair if the key does not exist yet

Parameters:

key (str) - The key to store under
value (any) - The value to store (should be picklable)
max_age (int) - Maximum age in seconds. If omitted or None the default is applied.

Returns: bool

Stored successfully?

replace(self, key, value, max_age=None)

source code

Set a key/value pair only if the key does exist already

Parameters:

key (str) - The key to store under
value (any) - The value to store (should be picklable)
max_age (int) - Maximum age in seconds. If omitted or None the default is applied.

Returns: bool

Stored successfully?

delete(self, key, block_time=None, all_pools=False)

source code

Delete a key/value pair from the cache

Parameters:

key (str) - The key to identify the item to delete
block_time (int) - Time to block add and replace requests for this key in seconds. If omitted or None, the blocking time is 0.
all_pools (bool) - Issue delete to each pool? This may be useful to enforce the deletion on backup pools, too. However, it won't delete the key from currently dead pools. So, it might be not that useful after all, but it's the best we can do from this side of the ocean.

Returns: bool

Whether it was really deleted from the main pool (or the current backup pool) of this key (i.e. whether it existed before)

get(self, *keys)

source code

Get a list of key/value pairs from the cache (if applicable)

The returned dict contains all pairs it could get. But keys maybe missing or the dict might be completely empty (of course).

Parameters:

keys (tuple) - The keys to fetch

Returns: dict

The dict of key/value pairs
