Use the CONFLATION topic property to select a conflation policy for a topic.
Conflation is configured through several settings.
Conflation can be enabled or disabled on a per session basis using the setConflated API call.
The default value for this is set using the conflates value in the queue-definition
section of Server.xml. In Diffusion™ 6.1, this is set to true
for a fresh installation.
You can specify the conflation policy for each topic when it is created, using the
CONFLATION topic property. The default policy is "conflate" (see below).
Use the CONFLATION topic property to set a topic's conflation policy using one of the following values.
