Compression and serialisation¶
Pyappcache offers pluggable compression and serialisation so you can choose what is used to compress your cache values and how they are serialised. The defaults are gzip and pickle.
Compression¶
- class pyappcache.compression.Compressor(*args, **kwds)¶
The protocol for compressors to follow
- is_compressed(data)¶
Takes some, possibly compressed data as an argument and returns True if is has been compressed with this compressor, False otherwise.
- Return type:
bool
- compress(data)¶
Compress the given bytes with this compressor
- Return type:
IO
[bytes
]
- decompress(data)¶
Decompress the given bytes with this compressor
- Return type:
IO
[bytes
]
Serialisation¶
- class pyappcache.serialisation.Serialiser(*args, **kwds)¶
The protocol for serialisers to follow
- class pyappcache.serialisation.PickleSerialiser¶
A wrapper for pickling.
The difference between this and pickle.load/pickle.dump is that
PickleSerialiser
returns None when it can’t unpickle - to defend against unreadable cache values.- pickle_protocol = 4¶
The pickle protocol level (default 4). Changing this default value will be considered a breaking API change.
