Why is Spark famous?Advantages of Using Apache Spark
There are many reasons for Spark's popularity, but some of the most important benefits include its speed, ease of use, and ability to handle large data sets.
Why is Spark so powerful?Apache Spark is powerful:
Apache Spark can handle many analytics challenges because of its low-latency in-memory data processing capability. It has well-built libraries for graph analytics algorithms and machine learning.
Why is Spark preferred?Spark is more efficient than Hadoop due to its real time processing. Most of the data scientist prefer to work with Spark as it less complex and because of its fast speed.
What is Spark best used for?Stream Processing and Structured Streaming: Spark can be used for batch processing and also has the capability to cater to stream processing use case with micro batches. Spark Streaming comes with Spark and one does not need to use any other streaming tools or APIs. Spark streaming also supports Structure Streaming.

When should you not use Spark?
When Not to Use Spark
- Ingesting data in a publish-subscribe model: In those cases, you have multiple sources and multiple destinations moving millions of data in a short time. ...
- Low computing capacity: The default processing on Apache Spark is in the cluster memory.
Why do companies use Spark?Fast data processing with spark has toppled apache Hadoop from its big data throne, providing developers with the Swiss army knife for real time analytics. Increasing speeds are critical in many business models and even a single minute delay can disrupt the model that depends on real-time analytics.
Is there anything better than Spark?The best alternatives to Spark are Polymail , HEY, and Airmail. If these 3 options don't work for you, we've listed over 20 alternatives below.
Why Spark is better than Python?Python is also a good option for prototyping machine learning models and data analysis. However, if you are working with large datasets and require distributed computing capabilities to process them efficiently, then Pyspark is the way to go.
What makes Spark better than Hadoop?Spark has been found to run 100 times faster in-memory, and 10 times faster on disk. It's also been used to sort 100 TB of data 3 times faster than Hadoop MapReduce on one-tenth of the machines. Spark has particularly been found to be faster on machine learning applications, such as Naive Bayes and k-means.
What are the cons of Spark?What are the disadvantages of Apache Spark? It has no file management system of its own, no real-time processing support, has issues with small files, and has a lesser number of algorithms. These are the key disadvantages of Apache Spark.
What is the most important feature of Spark?Fast processing: The most important feature of Apache Spark that has made the big data world choose this technology over others is its speed. Big data is characterized by its volume, variety, velocity, value, and veracity due to which it needs to be processed at a higher speed.
What is the main feature of Spark?The main feature of Spark is its in-memory cluster computing that increases the processing speed of an application. Spark is designed to cover a wide range of workloads such as batch applications, iterative algorithms, interactive queries and streaming.
How is Spark different from snowflake?Performance: The data processing capability of Snowflake is twice that of the Apache Spark analytics engine. In terms of performance and Total Cost of Ownership (TCO), Snowflake not only runs faster, but in many cases outperforms Spark by a large margin over the entire ETL cycle.
Why has Spark become a popular big data processing platform in recent years?Spark has proven very popular and is used by many large companies for huge, multi-petabyte data storage and analysis. This has partly been because of its speed.
Why is Spark better for machine learning?The Apache Spark machine learning library (MLlib) allows data scientists to focus on their data problems and models instead of solving the complexities surrounding distributed data (such as infrastructure, configurations, and so on).
What is faster SQL or Spark?MySQL can only use one CPU core per query, whereas Spark can use all cores on all cluster nodes. In my examples below, MySQL queries are executed inside Spark and run 5-10 times faster (on top of the same MySQL data). In addition, Spark can add “cluster” level parallelism.
Which language is better for Spark?“Scala is faster and moderately easy to use, while Python is slower but very easy to use.” Apache Spark framework is written in Scala, so knowing Scala programming language helps big data developers dig into the source code with ease, if something does not function as expected.
Why Spark instead of pandas?PySpark allows for parallel processing of data, while pandas does not. PySpark can read data from a variety of sources, including Hadoop Distributed File System (HDFS), Amazon S3, and local file systems, while pandas is limited to reading data from local file systems.
