Currently this is limited to - configuration for slow consumer detection. This configuration is based on the work - designed on the <ulink - url="http://cwiki.apache.org/confluence/display/qpid/Topic+Configuration+Design">design - wiki</ulink>.</para> - - <section id="Topic Identification"> - <title>Topic Identification</title> - <para>A configuration section has two entries that can be used to identify how the - configuration will be applied: 'name' and 'subscriptionName'. - - <programlisting> - <topic> - <name>stocks.us</name> - </programlisting> - <programlisting> - <topic> - <subscriptionName>clientid:mysubscription</subscriptionName> - </programlisting> - - It is also possible to combine these two identifiers to specify a unique subscription to - a given topic. - - <programlisting> - <topic> - <name>stocks.us</name> - <subscriptionName>clientid:mysubscription</subscriptionName> - </programlisting> - </para> - </section> - - <section> - <title>Configuration Items</title> - <para> Currently only one element of the designed configuration is processed, that of the - slow consumer detection. This is setup as below using the 'slow-consumer-detection' - element. There are two required types of tag, first the trigger, which is one of - 'depth', 'messageAge' or 'messageCount' and secondly the 'policy'. </para> - <programlisting> - <slow-consumer-detection> - <!-- The maximum depth before which the policy will be applied--> - <depth>4235264</depth> - - <!-- The maximum message age before which the policy will be applied--> - <messageAge>600000</messageAge> - - <!-- The maximum number of message before which the policy will be applied--> - <messageCount>50</messageCount> - - <!-- Policy Selection --> - <policy name="TopicDelete"/> - </slow-consumer-detection> - </programlisting> - - <para> The trigger is used to determine when the policy should be applied. Currently we have - a simple policy 'topicdelete', this will disconnect consumers of topics where their - consumption rate falls sufficiently to hit one of the trigger values. </para> - </section> - - - <section id="Limitiations"> - <title>Limitiations</title> - <para> As of 0.8 the topic configuration is limited to straight string matching. This means - that given the following two topic configuring sections for 'stocks.us' and 'stocks.*' a - subscription for 'stocks.uk' will not match the expected 'stocks.*'. Nor will any - additional configuration listed in 'stocks.*' affect any 'stocks.us' subscriptions. </para> - <programlisting> - <topics> - <topic> - <name>stocks.us</name> - ... - </topic> - <topic> - <name>stocks.*</name> - ... - </topic> - </topics> - </programlisting> - <para> A subscription for 'stocks.us' will only receive configuration settings that are - defined in the 'stocks.us' section. </para> - </section> - -</section> |
