What can Apache Spark be used for?

Can Apache Spark be used for AI?

Apache Spark (Spark) is an open source data-processing engine for large data sets. It is designed to deliver the computational speed, scalability, and programmability required for Big Data—specifically for streaming data, graph data, machine learning, and artificial intelligence (AI) applications.

Can Apache Spark be used for ETL?

Apache Spark is a very demanding and useful Big Data tool that helps to write ETL very easily. You can load the Petabytes of data and can process it without any hassle by setting up a cluster of multiple nodes.

What kind of data can be handled by Spark?

Spark Streaming framework helps in developing applications that can perform analytics on streaming, real-time data – such as analyzing video or social media data, in real-time. In fast-changing industries such as marketing, performing real-time analytics is very important.

When should you not use spark?

When Not to Use Spark

  1. 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. …
  2. Low computing capacity: The default processing on Apache Spark is in the cluster memory.

What is Apache Spark used 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 Apache Spark vs Hadoop?

Apache Hadoop and Apache Spark are both open-source frameworks for big data processing with some key differences. Hadoop uses the MapReduce to process data, while Spark uses resilient distributed datasets (RDDs).

Is PySpark an ETL?

There are many ETL tools available in the market that can carry out this process. A standard ETL tool like PySpark, supports all basic data transformation features like sorting, mapping, joins, operations, etc.

What does ETL stand for?

ETL stands for “extract, transform, load,” the three processes that, in combination, move data from one database, multiple databases, or other sources to a unified repository—typically a data warehouse.

Does Apache spark provide checkpoints?

Yes, Spark streaming uses checkpoint. Checkpoint is the process to make streaming applications resilient to failures. There are mainly two types of checkpoint one is Metadata checkpoint and another one is Data checkpoint.

What companies use Apache spark?

Internet powerhouses such as Netflix, Yahoo, and eBay have deployed Spark at massive scale, collectively processing multiple petabytes of data on clusters of over 8,000 nodes. It has quickly become the largest open source community in big data, with over 1000 contributors from 250+ organizations.
