>> Hello there, i want to write a simple messages  broker that if a message with a
specific topic arrives the broker will write it to hdfs (using JAVA HDFS API). have you any
ideas how to recognize (from the broker side) if a specific message of a topic arrives from
a producer? Then how to persistently save it anywhere else except the default persisten storage?

I am copying/pasting the answer I provided to this same question that
you asked on StackOverflow.

You could either implement your own ActiveMQ message store
for HDFS which would allow ActiveMQ to use HDFS as a persistence
store, or you could create an ActiveMQ broker plugin
( which would allow you
to intercept messages as they enter the broker. Both are very
different approaches, so it really depends on your requirements as to
which path to take.
