----------------------------------------
Summary: Clarify or remove ordering of elements in broadcast group
XML configuration
Key: ARTEMIS-3284
URL: https://issues.apache.org/jira/browse/ARTEMIS-3284
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: Configuration
Reporter: Étienne Hossack
The XSD requires the elements of the {{<broadcast-group>}} tags to be in order.
This is because an {{xsd:sequence}} element is used instead of {{xsd:all}}
It has been so since the HornetQ donation. {{<discovery-group>}} [is not
ordered|https://github.com/apache/activemq-artemis/blob/f491651fdbc911e11c470afb3c0f7f6da1d74063/artemis-server/src/main/resources/schema/artemis-configuration.xsd#L1371].
Users may encounter cryptic error messages such as the below if they apply
configuration [as in the
documentation|https://github.com/apache/activemq-artemis/blame/f491651fdbc911e11c470afb3c0f7f6da1d74063/docs/user-manual/en/clusters.md#L153]
There are 2 ways forward:
# Update the documentation, as the current schema is correct.
We assume the current schema is correct because this allows one to have an
unbounded number of {{<connector-ref>}} elements in broadcast groups
# Alter the current schema to allow exactly 1 connector ref, and remove the
ordering constraint.
I do not have sufficient familiarity with the functionality/intent of broadcast
groups to recommend the right approach here, but am happy to take follow
through on either path.
