Using the Amazon Simple Storage Service (S3), deletes a file or a folder from a bucket.
Usage Notes
The performance of this transformer is dependent on the amount of memory allocated to the Java Virtual Machine (JVM). The following environment variables allow you to specify memory available to Java Plugins:
- FME_JVM_MIN_HEAP_SIZE: Initial heap size for initializing the JVM. Default value is 1024K.
- FME_JVM_MAX_HEAP_SIZE: Maximum heap size for initializing JVM. Default value is 16384K.
If unset, the JVM applies the default values. If set, the values must be multiples of 1024K (for example, 4M and 64M, or 4096K and 32768K).
Note: To pass additional parameters used by FME to the Java Virtual Machine, use the JAVA_TOOL_OPTIONS environment variable.
Input Ports
Input
This transformer accepts any feature.
Output Ports
Output
Features which have successfully deleted a file or a folder from S3 are output through this port. Trying to delete an object or folder that does not exist or one that has already been deleted will also cause features to be output through this port.
<Rejected>
Features which have not successfully deleted a file or a folder from S3 are output through this port. Additionally, a message stored in an attribute specified in Error Attribute, will contain details about the failure.
Parameters
S3 Bucket
Bucket
The name of the Amazon S3 bucket.
Region
The AWS Region in which the specified Bucket resides. If the default value, US East, N. Virginia (us-east-1), is specified, and the specified Bucket does not reside there, the operation will still succeed. However, to optimize latency, it is best practice to specify the correct region.
Access Key
Specify a web connection to Amazon S3. Web connections can be reused in multiple workspaces, and connection parameters are hidden in the workspace. For more information, see Using Web Connections. Alternatively, check Embed Access Key (below) and specify the connection parameters manually.
Embed Access Key
When checked, you must specify the connection parameters to Amazon S3 manually. The connection parameters are visible in the workspace. To connect, specify:
Access Key ID
An access key associated with a user with permission to upload data to the specified bucket. If a pairing of an access key and a secret access key is not given, credentials will be searched in various locations listed here.
- In a file titled AwsCredentials.properties located in the Java classpath
- For the properties aws.accessKeyId and aws.secretKey in the Java system properties
- In the environment variables AWS_ACCESS_KEY_ID and AWS_SECRET_KEY
If credentials are still not found, the client will act as if it is in anonymous mode, where requests aren’t signed. This is useful if accessing a publicly accessible object or bucket.
Secret Access Key
A secret key paired with the access key provided. See the Access Key ID parameter for credential searching.
Delete Options
Object Type
Whether the object specified in Object Key is a file or a folder.
Object Key
The key identifying the file or folder to delete.
Output Options
Count Attribute
Name of the attribute that indicates the number of objects deleted by the S3Deleter.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
