Image storage
thumbor uses image storages to perform less retrievals of images from the sources, thus potentially saving expensive resources (such as outbound network).
thumbor comes with filesystem, redis and mongodb storages. There's also a nostorage storage for debugging or benchmarking purposes.
thumbor can store original images in the filesystem.
The file storage uses the FILE_STORAGE_ROOT_PATH configuration to save the images. It then joins the original image part of the URI to create the proper path to store the image in the filesystem.
There's a STORAGE_EXPIRATION_SECONDS option that will determine the time in seconds that a file is considered to be expired. When a file is expired, thumbor will try to retrieve the file using the specified Image Loader.
To use the filesystem storage set the configuration option of STORAGE to 'thumbor.storages.file_storage'.
This is a storage intended for debugging or benchmarking purposes. It does not store any images and always returns None when thumbor asks for an image.
In order to use this storage set the configuration option of STORAGE to 'thumbor.storages.no_storage'.
This is a storage intended for scenarios where you want to store the original images files one way and the security key another (or detector information).
A good example would be storing files in the filesystem, while storing security keys in a database.
In order to use this storage set the configuration option of STORAGE to 'thumbor.storages.mixed_storage'.
You must specify the MIXED_STORAGE_FILE_STORAGE, MIXED_STORAGE_CRYPTO_STORAGE and MIXED_STORAGE_DETECTOR_STORAGE options to define the original images storage, the security key storage and the detector results storage, respectively. Here's a sample configuration:
MIXED_STORAGE_FILE_STORAGE = 'thumbor.storages.file_storage'
MIXED_STORAGE_CRYPTO_STORAGE = 'thumbor.storages.redis_storage'
MIXED_STORAGE_DETECTOR_STORAGE = 'thumbor.storages.redis_storage'
FILE_STORAGE_ROOT_PATH = '/tmp/mypath'
REDIS_STORAGE_SERVER_HOST = 'localhost'
REDIS_STORAGE_SERVER_PORT = 6379
REDIS_STORAGE_SERVER_DB = 0As you can see, you still have to tell thumbor the specific configurations for each storage you choose.
thumbor-memcached - Thumbor-Community has a project that allows for storage in memcached.
TC-Redis - Thumbor-Community has a project that allows for both storage and result storage in redis.
TC-MongoDB - Thumbor-Community has a project that allows for both storage and result storage in mongodb.
If the built-in storages do not suit your needs, you can always implement your own storage and use it in the STORAGE configuration.
All you have to do is create a class called Storage that inherits from BaseStorage in your module, as can be seen in https://github.com/globocom/thumbor/blob/master/thumbor/storages/file_storage.py.
