Matthieu Morel created S4-99:
--------------------------------
Summary: Provide injectable load shedding mechanism
Key: S4-99
URL: https://issues.apache.org/jira/browse/S4-99
Project: Apache S4
Issue Type: Improvement
Reporter: Matthieu Morel
The main queues in S4 are the NIO buffer and the Stream event queue. The stream
event queue is a good place for implementing various load shedding strategies,
because metadata is available from the EventMessage class.
Currently, the default mechanism is avoid load shedding by using a blocking
write operation on the stream queue. We already experiment alternatives (see
S4-62), but the best way would be a pluggable mechanism.
