aws.sdk.s3

Functions to access the Amazon S3 storage service.

Each function takes a map of credentials as its first argument. The credentials map should contain an :access-key key and a :secret-key key, optionally an :endpoint key to denote an AWS endpoint and optionally a :proxy key to define a HTTP proxy to go through.

The :proxy key must contain keys for :host and :port, and may contain keys for :user, :password, :domain and :workstation.

get-objectclj

(get-object cred bucket key)
(get-object cred bucket key version-id)

Get an object from an S3 bucket. The object is returned as a map with the following keys: :content - an InputStream to the content :metadata - a map of the object's metadata :bucket - the name of the bucket :key - the object's key Be extremely careful when using this method; the :content value in the returned map contains a direct stream of data from the HTTP connection. The underlying HTTP connection cannot be closed until the user finishes reading the data and closes the stream. Therefore:

  • Use the data from the :content input stream as soon as possible
  • Close the :content input stream as soon as possible If these rules are not followed, the client can run out of resources by allocating too many open, but unused, HTTP connections.
