Hi Chris, Thanks for the quick reply! 3.9 MB heap (was the RSS also cca 4 MB?) is much smaller than I anticipated given this is running in the JVM. What's the trick? :)
I assume that DevelopmentSample app is the one from https://github.com/apache/incubator-edgent-samples/tree/develop/topology/src/main/java/org/apache/edgent/samples/topology ? How much bigger might the memory footprint be if one ran a more realistic app, say something that: * get data from JMX (so RMI involved) or calls some HTTP API that returns JSON (so parsing needed) * labels/tags data (like in the https://github.com/apache/incubator-edgent-samples/blob/develop/topology/src/main/java/org/apache/edgent/samples/topology/StreamTags.java ) ... but still no windowed analysis on the agent side. Are we then talking 10-20-30+ MB?
