Compositional
• Highly customizable operator based on basic building blocks
• Manual topology definition and optimization
TopologyBuilder builder = new TopologyBuilder();
builder.setSpout(“input", new RandomSentenceSpout(), 1);
builder.setBolt("split", new SplitSentence(), 3).shuffleGrouping("spout");
builder.setBolt("count", new WordCount(), 2).fieldsGrouping("split", new Fields("word"));

Observation
• Flink and Storm has close performance and are better choices to meet sub-
second SLA requirement if no repartition happened.
• Spark Streaming need to schedule task with additional context. Under tiny
batch interval case, the overhead could be dramatic worse compared to other
frameworks.
• According to our test, minimum Batch Interval of Spark is about 80ms (140
tasks per batch), otherwise task schedule delay will keep increasing
• Repartition is heavy for every framework, but usually it’s unavoidable.
• Latency of Gearpump is still quite low even under 800MB/s input throughput.

actual performance.
Observation
• Exactly-once semantics usually require state management and checkpoint.
But better guarantees come at high cost.
• There is no obvious performance difference in Flink when switching fault
tolerance on or off.
• Checkpoint mechanisms and storages play a critical role here.

  • 38. Observation • Flink and Storm has close performance and are better choices to meet sub- second SLA requirement if no repartition happened. • Spark Streaming need to schedule task with additional context. Under tiny batch interval case, the overhead could be dramatic worse compared to other frameworks. • According to our test, minimum Batch Interval of Spark is about 80ms (140 tasks per batch), otherwise task schedule delay will keep increasing • Repartition is heavy for every framework, but usually it’s unavoidable. • Latency of Gearpump is still quite low even under 800MB/s input throughput. 38

  • 42. Observation • Exactly-once semantics usually require state management and checkpoint. But better guarantees come at high cost. • There is no obvious performance difference in Flink when switching fault tolerance on or off. • Checkpoint mechanisms and storages play a critical role here. 42
