AWS micro instance

A scalable solution should scale both ways. Let's see how UncleK performs on a t2.micro AWS instance. All on one box.

• 1 instance, 4 topics, one of them is compacted, one has a short retention.
  • CPU when idle: 0.1%
  • CPU with 1 slow (300 records/s) producer: 0.4%
  • RAM: 75Mb used, 312Mb cache

Not bad really. Considering that default Apache Kafka installation won't even start on this instance. After some tweaking (export KAFKA_HEAP_OPTS="-Xmx512M -Xms512M") one can get it to launch.

• 1 instance, 4 topics, 1 partition each
  • CPU when idle: 2.6%
  • RAM: 634Mb used, 239Mb cache
