----------------------------------------
[~asasvari] and [~akatona] - Got the point and its valid. And thanks for
mentioning it. \
By the way how the appender behaves when kafka is down while its being
initialized? And what happens if the application ignores the appender
initialization exception and continues with application startup? there could be
a chance of NullPointer on producer?
