Bram de Kruijff commented on AMDATU-397:
----------------------------------------
Some Felix bundles supply metatype OCD, most do not. We could add them ourselfs
eg. in wrapped versions that handle multitenancy. The only moderately
interesting option at this point is managing eventadmin resource usage. I
suggest we forst work up the mt model before doing anything in this context.
Sample metatype for eventadmin for future reference:
{code}
<OCD id="org.apache.felix.eventadmin" name="Apache Felix EventAdmin
configuration">
<AD id="org.apache.felix.eventadmin.CacheSize" name="CacheSize"
type="Integer" cardinality="0" default="30"
required="false"
description="The size of various internal caches. The default value is
30. Increase in case of a large number (more then 100) of services. A value
less then 10 triggers the default value." />
<AD id="org.apache.felix.eventadmin.ThreadPoolSize" name="ThreadPoolSize"
type="Integer" cardinality="0" default="10"
required="false"
description="The size of the thread pool. The default value is 10.
Increase in case of a large amount of synchronous events where the event
handler services in turn send new synchronous events in the event dispatching
thread or a lot of timeouts are to be expected. A value of less then 2 triggers
the default value. A value of 2 effectively disables thread pooling." />
<AD id="org.apache.felix.eventadmin.Timeout" name="Timeout" type="Integer"
cardinality="0" default="5000"
required="false"
description="The black-listing timeout in milliseconds. The default value
is 5000. Increase or decrease at own discretion. A value of less then 100 turns
timeouts off. Any other value is the time in milliseconds granted to each event
handler before it gets blacklisted." />
<AD id="org.apache.felix.eventadmin.RequireTopic" name="RequireTopic"
type="Boolean" cardinality="0" default="true"
required="true"
description="The size of the thread pool. The default value is 10.
Increase in case of a large amount of synchronous events where the event
handler services in turn send new synchronous events in the event dispatching
thread or a lot of timeouts are to be expected. A value of less then 2 triggers
the default value. A value of 2 effectively disables thread pooling." />
<AD id="org.apache.felix.eventadmin.IgnoreTimeout" name="IgnoreTimeout"
type="String" cardinality="100" default=""
required="false"
description="Configure event handlers to be called without a timeout. If
a timeout is configured by default all event handlers are called using the
timeout. For performance optimization it is possible to configure event
handlers where the timeout handling is not used - this reduces the thread usage
from the thread pools as the timout handling requires an additional thread to
call the event handler. However, the application should work without this
configuration property. It is a pure optimization! The value is a list of
strings. If a string ends with a dot, all handlers in exactly this package are
ignored. If the string ends with a star, all handlers in this package and all
subpackages are ignored. If the string neither ends with a dot nor with a
start, this is assumed to define an exact class name." />
