Lead Platforms

Apache Storm

Apache Spark

Apache Samza

Apache Flink

Akka

Apache Storm

• Stream processing framework with micro-batching capabilities

• Included in most Hadoop distributions

• Main model (spouts and bolts) -One at a time -Lower latency -Operates on tuple streams• Trident -Micro-batching -Higher throughput

Apache Storm: Benefits vs. Challenges

• Broad adoption• Included in Hadoop distributions• Vibrant community • Extensibility • Support for different programming

languages

• Increasing competition from newer stacks

• Performance limitations at very large scale

Benefits Challenges

Apache Spark

• Micro-batching processing framework

• Elastic scalability models• Receivers split data into batches• Spark Streaming processes

batches and produces results• High throughput – higher latency • Functional APIs

Spark Streaming: Benefits vs. Challenges

• MPP infrastructure• Interoperability with other Spark

programming models (Java, Python, SQL)

• Integration with messaging frameworks

• Extensibility• Included in most Hadoop

distributions

• Time window queries• Complex infrastructure setup• Integration with line of business

systems

Benefits Challenges

Apache Samza

• Built to address some of the limitations of Apache Storm

• Deep integration with Samza and Yarn

• Simple API comparable to map-reduce

• Leverages Yarn for task distribution, fault tolerance and scalability

Apache Samza: Benefits vs. Challenges

• Highly scalable, fault-tolerant model

• Stateful stream data processing• Extensibility • Simple infrastructure

• Small adoption• Low level API• Heavy IO operations

Benefits Challenges

Apache Flink Streaming

• Alternative to Spark• Everything is a stream• Platform to unity batch and stream

processing• True streaming with adjustable

latency and throughput • Support different stream sources

and transformations

Apache Flink Streaming: Benefits vs. Challenges

• Combine batch and stream data processing

• Expressive APIs • Data flows and transformation • Extensiblity

• Small adoption• Limited state management • High availability models

Benefits Challenges

Akka Streams

• Micro-service, actor oriented model

• Messaging driven • Isolated failures• Reactive programming model

based on source, sinks and flows• DSL for stream data manipulation

Akka Streams: Benefits vs. Challenges

• Rich stream data processing model• Extensibility• Concurrency and thread-safey • Leverage mainstream Java and

Scala programming models

• Small adoption• Dependent on Akka’s architecture

style• Support for languages outside the

JVM

Benefits Challenges
