Key Differences Between Apache Storm vs Apache Spark
Streaming technologies are leading the Big Data world now. It becomes complex for the users to choose one. Apache Storm and Spark are the two most popular real-time technologies on the list.
Let’s compare Apache Storm and Spark on the basis of their features, and help users to make a choice. The purpose of this article Apache Storm Vs Apache Spark is not to make a judgment about one or other, but to study the similarities and differences between the two.
In this blog, Spark training in Bangalore will cover the differences between Apache Storm and Apache Spark. Let’s start first with the introduction to each, after that, we will move to the comparison of Apache Storm Vs Spark on the basis of the features of both.
Apache Storm is an open-source, fault-tolerant, scalable, and real-time stream processing computation system. It is the framework for real-time distributed data processing. It focuses on event processing or stream processing. Storm actualizes the fault-tolerant mechanism to perform a computation or to schedule multiple computations of an event. Apache storm is based on streams and tuples.
Apache Spark is designed to perform fast computation on the processing of large datasets. One needs to plug into a storage system and cluster resource manager of own choice.
Here we are going to explain the feature-wise difference between real-time processing tools like Apache Spark and Apache Storm.
Storm: Apache Storm holds the true streaming model for stream processing via the core storm layer.
Spark: Apache Spark Streaming acts as a wrapper over the batch processing.
Apache Storm provides a wide variety of primitives that perform tuple level processing at the stream intervals (functions, filters).
In Apache Spark, Output operators are used for writing information on the external systems and stream transformation operators are used to transforming DStream into another.
Storm: Apache Storm does not provide any framework for the storage of any intervening bolt output as a state. That’s why each application needs to create its state for itself whenever required.
Spark: No pluggable strategy can be applied for the implementation of state in the external system.
Storm: In Apache Storm, when a process fails, the supervisor process will restart it automatically as state management is managed by Zookeeper.
Spark: Apache Spark manages to again restart workers through resource manager which may be Mesos, YARN or its standalone manager.
Storm – At the worker process level, the executors run isolated for a particular topology. It shows that there is no the connection between topology tasks, and thus results in isolation at the time of execution. Also, an executor thread can run tasks of the same element only that avoid intermixing of tasks of different elements.
Spark – Spark application runs on the YARN cluster as a different application while the executors run in the YARN container.
The execution of different topologies is not possible in the same JVM, so YARN provides JVM level isolation. YARN also supports the organization of container level resource constraints, and thus provides resource-level isolation.
A certification is a credential that helps you stand out from the crowd. Get success in your career as a Spark developer by being a part of the Spark Training in Bangalore.

Apache Storm
Apache Storm is an open-source, fault-tolerant, scalable, and real-time stream processing computation system. It is the framework for real-time distributed data processing. It focuses on event processing or stream processing. Storm actualizes the fault-tolerant mechanism to perform a computation or to schedule multiple computations of an event.

Apache Spark
Apache Spark is designed to perform fast computation on the processing of large datasets. One needs to plug into a storage system and cluster resource manager of own choice.
Comparison between Apache Storm and Apache Spark
Here we are going to explain the feature-wise difference between real-time processing tools like Apache Spark and Apache Storm.
Processing Model
Storm: Apache Storm holds the true streaming model for stream processing via the core storm layer.
Spark: Apache Spark Streaming acts as a wrapper over the batch processing.
Primitives
Apache Storm provides a wide variety of primitives that perform tuple level processing at the stream intervals (functions, filters).
In Apache Spark, Output operators are used for writing information on the external systems and stream transformation operators are used to transforming DStream into another.
State Management
Storm: Apache Storm does not provide any framework for the storage of any intervening bolt output as a state. That’s why each application needs to create its state for itself whenever required.
Spark: No pluggable strategy can be applied for the implementation of state in the external system.
Fault-Tolerant
Storm: In Apache Storm, when a process fails, the supervisor process will restart it automatically as state management is managed by Zookeeper.
Spark: Apache Spark manages to again restart workers through resource manager which may be Mesos, YARN or its standalone manager.
Isolation
Storm – At the worker process level, the executors run isolated for a particular topology.
