-RE: Multiplexing to multiple JdbcChannel (Derby) + event header ?
Alain B. 2013-01-23, 08:01
Ok, I got it thank you. I'll follow your advice and go for file channels instead.
W.r.t. the interceptor, I'll implement a custom org.apache.flume.interceptor class.
Just one more question: interceptors are configured in the source configuration. But are they executed before the events are inserted in the source or when they get out of the source (before going to the channel). If it's the later case, then I suppose it's done before any selector does its job (multiplexing on the basis of a header in my specific case).
So is it :
log4jappender -> interceptor -> source -> selector -> channel
log4jappender -> source -> interceptor -> selector -> channel
