Puts FlowFiles to an Amazon S3 Bucket.
The upload uses either the PutS3Object method or the PutS3MultipartUpload method. The PutS3Object method sends the file in a single synchronous call, but it has a 5GB size limit. Larger files are sent using the PutS3MultipartUpload method. This multipart process saves state after each step so that a large upload can be resumed with minimal loss if the processor or cluster is stopped and restarted.
A multipart upload consists of three steps:
1) initiate upload,
2) upload the parts, and
3) complete the upload.
For multipart uploads, the processor saves state locally tracking the upload ID and parts uploaded, which must both be provided to complete the upload.
The AWS libraries select an endpoint URL based on the AWS region, but this can be overridden with the 'Endpoint Override URL' property for use with other S3-compatible endpoints.
The S3 API specifies that the maximum file size for a PutS3Object upload is 5GB. It also requires that parts in a multipart upload must be at least 5MB in size, except for the last part. These limits establish the bounds for the Multipart Upload Threshold and Part Size properties.
| Display Name | API Name | Default Value | Allowable Values | Description |
|---|
| Object Key | Object Key | ${filename} | | The S3 Object Key to use. This is analogous to a filename for traditional file systems.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Bucket | Bucket | | | The S3 Bucket to interact with
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Content Type | Content Type | | | Sets the Content-Type HTTP header indicating the type of content stored in the associated object. The value of this header is a standard MIME type.
AWS S3 Java client will attempt to determine the correct content type if one hasn't been set yet. Users are responsible for ensuring a suitable content type is set when uploading streams. If no content type is provided and cannot be determined by the filename, the default content type "application/octet-stream" will be used.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Content Disposition | Content Disposition | | | Sets the Content-Disposition HTTP header indicating if the content is intended to be displayed inline or should be downloaded.
Possible values are 'inline' or 'attachment'. If this property is not specified, object's content-disposition will be set to filename. When 'attachment' is selected, '; filename=' plus object key are automatically appended to form final value 'attachment; filename="filename.jpg"'. |
| Cache Control | Cache Control | | | Sets the Cache-Control HTTP header indicating the caching directives of the associated object. Multiple directives are comma-separated.

| Object Tags Prefix | s3-object-tags-prefix | | | Specifies the prefix which would be scanned against the incoming FlowFile's attributes and the matching attribute's name and value would be considered as the outgoing S3 object's Tag name and Tag value respectively. For Ex: If the incoming FlowFile carries the attributes tagS3country, tagS3PII, the tag prefix to be specified would be 'tagS3'
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry) |
| Remove Tag Prefix | s3-object-remove-tags-prefix | False | | If set to 'True', the value provided for 'Object Tags Prefix' will be removed from the attribute(s) and then considered as the Tag name. For ex: If the incoming FlowFile carries the attributes tagS3country, tagS3PII and the prefix is set to 'tagS3' then the corresponding tag values would be 'country' and 'PII' |
