RabbitMQ Consumer Properties

The following properties are available for Rabbit consumers only and must be prefixed with spring.cloud.stream.rabbit.bindings.<channelName>.consumer..

However if the same set of properties needs to be applied to most bindings, to avoid repetition, Spring Cloud Stream supports setting values for all channels, in the format of spring.cloud.stream.rabbit.default.<property>=<value>.

Also, keep in mind that binding specific property will override its equivalent in the default.

acknowledgeMode

The acknowledge mode.

Default: AUTO.

anonymousGroupPrefix

When the binding has no group property, an anonymous, auto-delete queue is bound to the destination exchange. The default naming stragegy for such queues results in a queue named anonymous.<base64 representation of a UUID>. Set this property to change the prefix to something other than the default.

Default: anonymous..

autoBindDlq

Whether to automatically declare the DLQ and bind it to the binder DLX.

Default: false.

bindingRoutingKey

The routing key with which to bind the queue to the exchange (if bindQueue is true). Can be multiple keys - see bindingRoutingKeyDelimiter. For partitioned destinations, -<instanceIndex> is appended to each key.

Default: #.

bindingRoutingKeyDelimiter

When this is not null, 'bindingRoutingKey' is considered to be a list of keys delimited by this value; often a comma is used.

Default: null.

bindQueue

Whether to declare the queue and bind it to the destination exchange. Set it to false if you have set up your own infrastructure and have previously created and bound the queue.

Default: true.

consumerTagPrefix

Used to create the consumer tag(s); will be appended by #n where n increments for each consumer created. Example: ${spring.application.name}-${spring.cloud.stream.bindings.input.group}-${spring.cloud.stream.instance-index}.

Default: none - the broker will generate random consumer tags.

containerType

Select the type of listener container to be used. See Choosing a Container in the Spring AMQP documentation for more information. Also see [rabbitmq-stream].

Default: simple

deadLetterQueueName

The name of the DLQ

Default: prefix+destination.dlq

deadLetterExchange

A DLX to assign to the queue. Relevant only if autoBindDlq is true.

Default: 'prefix+DLX'

deadLetterExchangeType

The type of the DLX to assign to the queue. Relevant only if autoBindDlq is true.

Default: 'direct'

deadLetterRoutingKey

A dead letter routing key to assign to the queue. Relevant only if autoBindDlq is true.

Default: destination

declareDlx

Whether to declare the dead letter exchange for the destination. Relevant only if autoBindDlq is true. Set to false if you have a pre-configured DLX.

Default: true.

declareExchange

Whether to declare the exchange for the destination.

Default: true.

delayedExchange

Whether to declare the exchange as a Delayed Message Exchange. Requires the delayed message exchange plugin on the broker. The x-delayed-type argument is set to the exchangeType.

Default: false.

dlqBindingArguments

Arguments applied when binding the dlq to the dead letter exchange; used with headers deadLetterExchangeType to specify headers to match on. For example …​dlqBindingArguments.x-match=any, …​dlqBindingArguments.someHeader=someValue.

Default: empty

dlqDeadLetterExchange

If a DLQ is declared, a DLX to assign to that queue.

Default: none

dlqDeadLetterRoutingKey

If a DLQ is declared, a dead letter routing key to assign to that queue.

Default: none

dlqExpires

How long before an unused dead letter queue is deleted (in milliseconds).

Default: no expiration

dlqLazy

Declare the dead letter queue with the x-queue-mode=lazy argument. See “Lazy Queues”. Consider using a policy instead of this setting, because using a policy allows changing the setting without deleting the queue.

Default: false.

dlqMaxLength

Maximum number of messages in the dead letter queue.

Default: no limit

dlqMaxLengthBytes

Maximum number of total bytes in the dead letter queue from all messages.

Default: no limit

dlqMaxPriority

Maximum priority of messages in the dead letter queue (0-255).

Default: none

dlqOverflowBehavior

Action to take when dlqMaxLength or dlqMaxLengthBytes is exceeded; currently drop-head or reject-publish but refer to the RabbitMQ documentation.

Default: none

dlqQuorum.deliveryLimit

When quorum.enabled=true, set a delivery limit after which the message is dropped or dead-lettered.

Default: none - broker default will apply.

dlqQuorum.enabled

When true, create a quorum dead letter queue instead of a classic queue.

Default: false

dlqQuorum.initialGroupSize

When quorum.enabled=true, set the initial quorum size.

Default: none - broker default will apply.

dlqSingleActiveConsumer

Set to true to set the x-single-active-consumer queue property to true.

Default: false

dlqTtl

Default time to live to apply to the dead letter queue when declared (in milliseconds).

Default: no limit

durableSubscription

Whether the subscription should be durable. Only effective if group is also set.

Default: true.

exchangeAutoDelete

If declareExchange is true, whether the exchange should be auto-deleted (that is, removed after the last queue is removed).

Default: true.

exchangeDurable

If declareExchange is true, whether the exchange should be durable (that is, it survives broker restart).

Default: true.

exchangeType

The exchange type: direct, fanout, headers or topic for non-partitioned destinations and direct, headers or topic for partitioned destinations.

Default: topic.

exclusive

Whether to create an exclusive consumer. Concurrency should be 1 when this is true. Often used when strict ordering is required but enabling a hot standby instance to take over after a failure. See recoveryInterval, which controls how often a standby instance attempts to consume. Consider using singleActiveConsumer instead when using RabbitMQ 3.8 or later.

Default: false.

expires

How long before an unused queue is deleted (in milliseconds).

Default: no expiration

failedDeclarationRetryInterval

The interval (in milliseconds) between attempts to consume from a queue if it is missing.

Default: 5000

frameMaxHeadroom

The number of bytes to reserve for other headers when adding the stack trace to a DLQ message header. All headers must fit within the frame_max size configured on the broker. Stack traces can be large; if the size plus this property exceeds frame_max then the stack trace will be truncated. A WARN log will be written; consider increasing the frame_max or reducing the stack trace by catching the exception and throwing one with a smaller stack trace.

Default: 20000

headerPatterns

Patterns for headers to be mapped from inbound messages.

Default: ['*'] (all headers).

lazy

Declare the queue with the x-queue-mode=lazy argument. See “Lazy Queues”. Consider using a policy instead of this setting, because using a policy allows changing the setting without deleting the queue.

Default: false.

maxConcurrency

The maximum number of consumers. Not supported when the containerType is direct.

Default: 1.

maxLength

The maximum number of messages in the queue.

Default: no limit

maxLengthBytes

The maximum number of total bytes in the queue from all messages.

Default: no limit

maxPriority

The maximum priority of messages in the queue (0-255).

Default: none

missingQueuesFatal

When the queue cannot be found, whether to treat the condition as fatal and stop the listener container. Defaults to false so that the container keeps trying to consume from the queue — for example, when using a cluster and the node hosting a non-HA queue is down.

Default: false

overflowBehavior

Action to take when maxLength or maxLengthBytes is exceeded; currently drop-head or reject-publish but refer to the RabbitMQ documentation.

Default: none

prefetch

Prefetch count.

Default: 1.

prefix

A prefix to be added to the name of the destination and queues.

Default: "".

queueBindingArguments

Arguments applied when binding the queue to the exchange; used with headers exchangeType to specify headers to match on. For example …​queueBindingArguments.x-match=any, …​queueBindingArguments.someHeader=someValue.

Default: empty

queueDeclarationRetries

The number of times to retry consuming from a queue if it is missing. Relevant only when missingQueuesFatal is true. Otherwise, the container keeps retrying indefinitely. Not supported when the containerType is direct.

Default: 3

queueNameGroupOnly

When true, consume from a queue with a name equal to the group. Otherwise the queue name is destination.group. This is useful, for example, when using Spring Cloud Stream to consume from an existing RabbitMQ queue.

Default: false.

quorum.deliveryLimit

When quorum.enabled=true, set a delivery limit after which the message is dropped or dead-lettered.

Default: none - broker default will apply.

quorum.enabled

When true, create a quorum queue instead of a classic queue.

Default: false

quorum.initialGroupSize

When quorum.enabled=true, set the initial quorum size.

Default: none - broker default will apply.

recoveryInterval

The interval between connection recovery attempts, in milliseconds.

Default: 5000.

requeueRejected

Whether delivery failures should be re-queued when retry is disabled or republishToDlq is false.

Default: false.

republishDeliveryMode

When republishToDlq is true, specifies the delivery mode of the republished message.

Default: DeliveryMode.PERSISTENT

republishToDlq

By default, messages that fail after retries are exhausted are rejected. If a dead-letter queue (DLQ) is configured, RabbitMQ routes the failed message (unchanged) to the DLQ. If set to true, the binder republishs failed messages to the DLQ with additional headers, including the exception message and stack trace from the cause of the final failure. Also see the frameMaxHeadroom property.

Default: true

singleActiveConsumer

Set to true to set the x-single-active-consumer queue property to true.

Default: false

transacted

Whether to use transacted channels.

Default: false.

ttl

Default time to live to apply to the queue when declared (in milliseconds).

Default: no limit

txSize

The number of deliveries between acks. Not supported when the containerType is direct.

Default: 1.
