Procedure
-
You may choose any resource location; however, we recommend not using the

To check if a bucket already exists, you can use the
tS3BucketExist component. Add a
tS3BucketExist component and connect it to the
tS3Connection component with an
OnComponentOk trigger.
This component can reuse the connection information from the tS3Connection component:
-
This component reports the existence of the S3 bucket as a Boolean global
variable named tS3BucketExist_1.BUCKET_EXIST:
-
To create the bucket if it doesn't already exist, add a
tS3BucketCreate component and connect it to
tS3BucketExist with a Run If
trigger.
Set the condition on the Run If trigger as follows:
This condition means that the tS3BucketCreate will execute only if the bucket does not exist.
-
Open the Component view of the
tS3BucketCreate component and provide the bucket
name:

When the Job has executed, from the Amazon Web Services home page, navigate to S3:
You will reach the Amazon S3 home page, where you can see the list of your buckets. You should find your new bucket created from the Talend Studio:
In a similar way, you can delete an existing bucket using the tS3BucketDelete component.
Warning:Make sure that your bucket name is unique. Otherwise, you may inadvertently work on someone else's bucket.
