---------------------------------------
Summary: camel-core - Throttle EIP: do not reschedule the clean of
the throttling state on every exchange
Key: CAMEL-26472
URL: https://issues.apache.org/jira/browse/CAMEL-26472
Project: Camel
Issue Type: Sub-task
Reporter: Adriano Machado
Assignee: Adriano Machado
Fix For: 4.24.0
Tier 2 item of CAMEL\-25132. On every exchange, both throttler modes schedule a
new clean of the throttling state and cancel the previous one, which takes the
scheduled executor queue lock about three times. {{ThrottlePermit.compareTo}}
also reads the clock twice per comparison, although it only needs to compare
the two scheduled times.
The pending clean can be kept while it is not close to firing, and only
rescheduled otherwise. In total requests mode the clean removes a state whose
permits are all returned, even if they are still delayed \(see CAMEL\-25300\),
so a clean must stay at least one period after the last return. Keeping it only
while it is at least two periods away ensures that. A clean then runs between 8
and 10 periods after the last permit was returned, instead of exactly 10.
