GCP Credentials Provider ServiceGCP Credentials Provider ServiceController Service API:
GCPCredentialsService
Implementation: GCPCredentialsControllerService		The Controller Service used to obtain Google Cloud Platform credentials.
Number of retriesgcp-retry-count6How many retry attempts should be made before routing to the failure relationship.
Proxy hostgcp-proxy-hostIP or hostname of the proxy to be used. You might need to set the following properties in bootstrap for https proxy usage: -Djdk.http.auth.tunneling.disabledSchemes= -Djdk.http.auth.proxying.disabledSchemes=

Proxy Configuration Serviceproxy-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
Storage API URLstorage-api-urlOverrides the default storage URL. Configuring an alternative Storage API URL also overrides the HTTP Host header on requests as described in the Google documentation for Private Service Connections.
Supports Expression Language: true (will be evaluated using variable registry only)
Bucketgcs-bucket${gcs.bucket}Bucket of the object.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Keygcs-key${filename}Name of the object.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Content Typegcs-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 Hashgcs-object-md5MD5 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 Checksumgcs-object-crc32cCRC32C Checksum (encoded in Base64, big-Endian order) of the file for server-side validation.
Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
Object ACLgcs-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 Keygcs-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 Objectgcs-overwrite-objecttrue
  • true
  • false
If false, the upload to GCS will succeed only if the object does not exist.
Content Disposition Typegcs-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
GZIP Compression Enabledgzip.content.enabledtrue
  • true
  • false
Signals to the GCS Blob Writer whether GZIP compression during transfer is desired. False means do not gzip and can boost performance in many cases.
