-----------------------------

Latest update.
Contains a proposal for free-format queries - this may not exactly belong in the API section, so feel free to move it.
And a number of small tweaks.

[jira] Commented: (QPID-2248) QMF: proposed API for QMFv2
Posted by "Ted Ross (JIRA)" <qp...@incubator.apache.org>.
[ https://issues.apache.org/jira/browse/QPID-2248?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12786940#action_12786940 ]
Ted Ross commented on QPID-2248:
--------------------------------
A couple of reasons:
First, the distinction was used to separate the transmission of properties (possibly bulky) from the transmission of statistics (change frequently) in an attempt to make bandwidth usage more efficient. Furthermore, it was the intent (but never implemented) that changes to properties would be transmitted immediately and that changes to statistics would be bundled and sent periodically.
With the map-message format, there is no need to separate the data elements in an object into separate classes (i.e. properties and statistics) because it is easy to send an update message that contains only the elements that have changed.
In the new structure, "described data" (i.e. a data structure described by a schema) has "properties" and "methods". Properties, as described by the scheme, have attributes (amqp-type, access-rule, optional/mandatory, description, units, etc.). We will add an additional attribute describing whether a property is discrete or continuous which will determine whether it should be periodically sampled or whether updates should be triggered on any change.
This new structure simplifies the code and the related concepts but retains (and improves) the current functionality.

Ken Giusti commented on QPID-2248:
----------------------------------
My summary is a bit oversimplified: I'm proposing that we move the distinction between what is a "statistic" and what is a non-statistic out of the functional API and make it part of the schema that describes the data instead.
This results in QMF not needing to know if a bit of data is considered a "statistic" or a "property" - that's left to the application that uses the data. QMF becomes more data-agnostic.
An additional benefit is that this simplifies the API proper quite a bit. Looking at the code as it stands now, for every "getProperty()"-like call, there is a parallel "getStatistic()" call. In reality, QMF doesn't really distinguish between the two. Removing this distinction in the API makes a lot of code duplication go away.
We kept the term "property" because it's generic - it now applies to all data (non-method) items.
thanks,
-K
