Properties:

In the list below, the names of required properties appear in bold. Any other properties (not in bold) are considered optional. The table also indicates any default values, whether a property supports the NiFi Expression Language, and whether a property is considered "sensitive", meaning that its value will be encrypted. Before entering a value in a sensitive property, ensure that the nifi.properties file has an entry for the property nifi.sensitive.props.key.

Proxy Configuration ServiceController Service API:
ProxyConfigurationService
Implementation: StandardProxyConfigurationService
Specifies the Proxy Configuration Controller Service to proxy network requests. If set, it supersedes proxy settings configured per component. Supported proxies: HTTP + AuthN
Bucket${gcs.bucket}Bucket of the object.

Key${filename}Name of the object.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Content Type${mime.type}Content Type for the file, i.e. text/plain
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
MD5 HashMD5 Hash (encoded in Base64) of the file for server-side validation.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
CRC32C ChecksumCRC32C Checksum (encoded in Base64, big-Endian order) of the file for server-side validation.

Object ACL
  • All Authenticated Users Gives the bucket or object owner OWNER permission, and gives all authenticated Google account holders READER and WRITER permissions. All other permissions are removed.
  • Authenticated Read Gives the bucket or object owner OWNER permission, and gives all authenticated Google account holders READER permission. All other permissions are removed.
  • Bucket Owner Full Control Gives the object and bucket owners OWNER permission. All other permissions are removed.
  • Bucket Owner Read Only Gives the object owner OWNER permission, and gives the bucket owner READER permission. All other permissions are removed.
  • Private Gives the bucket or object owner OWNER permission for a bucket or object, and removes all other access permissions.
  • Project Private Gives permission to the project team based on their roles. Anyone who is part of the team has READER permission. Project owners and project editors have OWNER permission. This is the default ACL for newly created buckets. This is also the default ACL for newly created objects unless the default object ACL for that bucket has been changed.
  • Public Read Only Gives the bucket or object owner OWNER permission, and gives all users, both authenticated and anonymous, READER permission. When you apply this to an object, anyone on the Internet can read the object without authenticating.
Access Control to be attached to the object uploaded. Not providing this will revert to bucket defaults.
Server Side Encryption KeyAn AES256 Encryption Key (encoded in base64) for server-side encryption of the object.
Sensitive Property: true
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Overwrite Objecttrue
  • true
  • false
If false, the upload to GCS will succeed only if the object does not exist.
Content Disposition Type
  • Inline Indicates that the object should be loaded and rendered within the browser.
  • Attachment Indicates that the object should be saved (using a Save As... dialog) rather than opened directly within the browser
Type of RFC-6266 Content Disposition to be attached to the object

Dynamic Properties:

Dynamic Properties allow the user to specify both the name and value of a property.
