No I want to check plain user credentials for authentication against an external system. Where best to plug in this check. I thought the new AuthenticateCallbackHandler would be convenient, but I am very much in doubt if this is the right way. It is also not clear for me from the docs how to implement this.
Please see my stackoverflow question for a minimal test setup which I try to get working. https://stackoverflow.com/questions/50412589/kafka-custom-authenticatecallbackhandler Any help/pointers/examples is much appreciated! > Op 1 jun. 2018 om 21:05 heeft Martin Gainty <mgai...@hotmail.com> het > volgende geschreven: > > are you referring to onCompleteCallback from > > https://github.com/apache/kafka/commit/837f31dd1850b179918f83338b4b4487486b2c58 > > [https://avatars2.githubusercontent.com/u/14958864?s=200&v=4]<https://github.com/apache/kafka/commit/837f31dd1850b179918f83338b4b4487486b2c58> > > KAFKA-6927; Chunked down-conversion to prevent out of memory errors o… · > apache/kafka@837f31d<https://github.com/apache/kafka/commit/837f31dd1850b179918f83338b4b4487486b2c58> > github.com > …n broker [KIP-283] (#4871) Implementation for lazy down-conversion in a > chunked manner for efficient memory usage during down-conversion.
