The main reason I can't have pre-defined topics (in properties file or
database) is because symbols are changed every day (some may be added, some may
be deleted, some may just change slightly).
Maintaining an accurate list of these symbols is not trivial (some large banks
have groups dedicated to this).
After sending the original message, I realized that I might be able to take advantage of
selectors or 'where clause' like functionality. In other words, I could subscribe to
level1 but limit the values to "symbol=MSFT" (which means only MSFT should
travel down the wire to the client, nothing else). Can't find if qpid has this
capability or not though.
you can also use the exclusive binding key feature. it has been used for
this use case before
