Consumes AMQP Messages from an AMQP Broker using the AMQP 0.9.1 protocol. Each message that is received from the AMQP Broker will be emitted as its own FlowFile to the 'success' relationship.

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, and whether a property supports the NiFi Expression Language.

Display NameAPI NameDefault ValueAllowable ValuesDescription
QueueQueueThe name of the existing AMQP Queue from which messages will be consumed. Usually pre-defined by AMQP administrator.
Auto-Acknowledge Messagesauto.acknowledgefalse
  • true
  • false
If false (Non-Auto-Acknowledge), the messages will be acknowledged by the processor after transferring the FlowFiles to success and committing the NiFi session. Non-Auto-Acknowledge mode provides 'at-least-once' delivery semantics. If true (Auto-Acknowledge), messages that are delivered to the AMQP Client will be auto-acknowledged by the AMQP Broker just after sending them out. This generally will provide better throughput but will also result in messages being lost upon restart/crash of the AMQP Broker, NiFi or the processor. Auto-Acknowledge mode provides 'at-most-once' delivery semantics and it is recommended only if loosing messages is acceptable.
Batch Sizebatch.size10The maximum number of messages that should be processed in a single session. Once this many messages have been received (or once no more messages are readily available), the messages received will be transferred to the 'success' relationship and the messages will be acknowledged to the AMQP Broker. Setting this value to a larger number could result in better performance, particularly for very small messages, but can also result in more messages being duplicated upon sudden restart of NiFi.
Remove Curly Bracesremove.curly.bracesFalse
  • True
  • False
If true Remove Curly Braces, Curly Braces in the header will be automatically remove.
Header Separatorheader.separator,The character that is used to separate key-value for header in String. The value must only one character.Otherwise you will get an error message
BrokersBrokersA comma-separated list of known AMQP Brokers in the format <host>:<port> (e.g., localhost:5672). If this is set, Host Name and Port are ignored. Only include hosts from the same AMQP cluster.
Supports Expression Language: true (will be evaluated using variable registry only)
Host NameHost NamelocalhostNetwork address of AMQP broker (e.g., localhost). If Brokers is set, then this property is ignored.
Supports Expression Language: true (will be evaluated using variable registry only)
PortPort5672Numeric value identifying Port of AMQP broker (e.g., 5671). If Brokers is set, then this property is ignored.
Supports Expression Language: true (will be evaluated using variable registry only)
Virtual HostVirtual HostVirtual Host name which segregates AMQP system for enhanced security.
Supports Expression Language: true (will be evaluated using variable registry only)
User NameUser NameUser Name used for authentication and authorization.
Supports Expression Language: true (will be evaluated using variable registry only)
PasswordPasswordPassword used for authentication and authorization.
Sensitive Property: true
AMQP VersionAMQP Version0.9.1
  • 0.9.1
AMQP Version. Currently only supports AMQP v0.9.1.
SSL Context Servicessl-context-serviceController Service API:
Implementations: StandardRestrictedSSLContextService
The SSL Context Service used to provide client certificate information for TLS/SSL connections.
Use Client Certificate Authenticationcert-authenticationfalse
  • true
  • false
Authenticate using the SSL certificate rather than user name/password.
Client Authssl-client-authNONE
  • WANT
  • NONE
The property has no effect and therefore deprecated.
