Support for timestamping messages on arrival at the broker.
-----------------------------------------------------------
Key: QPID-3417
URL: https://issues.apache.org/jira/browse/QPID-3417
Project: Qpid
Issue Type: New Feature
Components: C++ Broker
Affects Versions: 0.13
Reporter: Ken Giusti
Assignee: Ken Giusti
Priority: Minor
Fix For: 0.14
AMQP 0.10 defines an optional message delivery property of timestamp:
name: timestamp
type: datetime
description: message timestamp
(optional) The timestamp is set by the broker on arrival of the message.
I'd like to make use of this timestamp for a proposed debugging feature for
message groups. See the message groups UI proposal in
https://issues.apache.org/jira/browse/QPID-3346 for details of its use.
I think it would more useful to introduce a generic message timestamp
capability based on the AMQP 0.10 delivery property, rather than integrate
something limited only to message groups.
Functional Model:
The broker would support the configuration of a "timestamp interval". This
interval would be expressed in millisecond units, and would represent the
granularity of the message timestamp. The default setting of this interval
would be zero - which would be interpreted as disabled. When enabled
(non-zero) the broker would maintain a time-of-day time stamp. This time stamp
would be updated (resync'ed to the current time-of-day) periodically based on
the configured "timestamp interval".
When enabled, each message arriving at the broker will have the "timestamp"
delivery property set to the current value of the broker's time stamp.
This feature will need to be able to be turned on and off on demand, without
restarting the broker. Therefore new QMF methods would be added to the
broker's QMF object to support run-time configuration:
method: getMessageTimestamp - returns the configured timestamp value for the
broker in milliseconds.
method: setMessageTimestamp - sets the broker's timestamp value (expressed
in milliseconds).
