public class S3Tap
extends cascading.tap.Tap<java.util.Properties,java.io.InputStream,java.io.OutputStream>
implements cascading.tap.type.FileType<java.util.Properties>, cascading.tap.type.TapWith<java.util.Properties,java.io.InputStream,java.io.OutputStream>

Class S3Tap is a Cascading local-mode Tap providing read and write access to data stored in Amazon S3 buckets.

This Tap is not intended to be used with any of the other Cascading planners unless they specify they are local-mode compatible.

S3Tap can read a single key, all objects underneath a key-prefix, or all objects under a key-prefix that match a given globbing pattern.

See the various constructors for the available access parametrizations. Of note are the constructors that take a URI instance. The URI should be in the following format: s3://[bucket]/<key|key-prefix><?glob>

Where bucket is the only required value. The key references a single object, the key-prefix is used to access a set of objects with a common prefix value. The glob value is use to further narrow the resulting object set.

The globbing pattern is specified by the FileSystem.getPathMatcher(java.lang.String) method.

This Tap was designed to allow applications to effectively poll an S3 bucket for new keys to be processed.

When used with the S3FileCheckpointer class, a map of keys last consumed by each bucket will be tracked on disk, with the map surviving JVM restarts allowing for applications to exit and restart safely without retrieving duplicate data.

The S3Checkpointer.commit() method is only called during a graceful shutdown of the Flow or JVM, but every consumed key is passed to the S3Checkpointer, so custom implementations can choose to persist the key more frequently.

AWS Credentials are handled by DefaultAWSCredentialsProviderChain.
