Method Details
-
init
Deprecated.Initialize this processor with the given context. The framework ensures this is called once per processor when the topology that contains it is initialized. When the framework is done with the processor,close()
will be called on it; the framework may later re-use the processor by calling#init()
again.The provided
context
can be used to access topology and record meta data, toschedule
a method to becalled periodically
and to access attachedStateStore
s.- Parameters:
context
- the context; may not be null
-
process
Deprecated.Process the record with the given key and value.- Parameters:
key
- the key for the recordvalue
- the value for the record
-
close
void close()Deprecated.Close this processor and clean up any resources. Be aware that#close()
is called after an internal cleanup. Thus, it is not possible to write anything to Kafka as underlying clients are already closed. The framework may later re-use this processor by calling#init()
on it again.Note: Do not close any streams managed resources, like
StateStore
s here, as they are managed by the library.
