Hi,
we send position data containing xPos and yPos and the senders ID as key. Now
we would like to receive just data from senders in a given distance. The doc
mentions ContentFilteredTopic but I'm do not really get how to use this.
Earlier it mentions MultiTopics and that you can xomehow specify filters in
SQL. How would you realize something like
SELECT * FROM positions WHERE ABS(pos - thisPos) < distance
with a ContentFilteredTopic? Do I understand it correct that a
ContentFilteredTopic is published to the domain again and maybe it's the wrong
approach to filter this dynamic (since the senders are moving) data?
regards
Knut
