What is modern data ecosystem and how can businesses process this enormous incoming data flow? Let’s overview a general data engineering stack. 

Big Data Frameworks 

Big data frameworks are essential for handling and processing large datasets across distributed computing environments efficiently. These contain structured, semi-structured, or unstructured data. Datasets can range in size from terabytes to petabytes to exabytes. Here are the  

  • Hadoop: An open-source framework that allows for the distributed storage and processing of large data sets across clusters of computers using simple programming models. Its main components are the Hadoop Distributed File System (HDFS) and a data processing engine that implements the MapReduce program for filtering and sorting data. 
  • Spark: A unified analytics engine for big data processing, known for its speed and ease of use, offering high-level APIs in Java, Scala, Python, and R. is intended to run faster than Map Reduce by processing data and holding it in memory for subsequent steps rather than writing the results directly back to memory. This allows Spark to be up to 100 times faster than Hadoop for smaller workloads. 
  • Hive: A data warehouse software built on top of Hadoop, facilitating data query and analysis through a SQL-like interface, enabling easy data summarization and ad-hoc queries. Apache Hive allows developers to use Hive Query Language (HQL) statements similar to standard SQL statements for data query and analysis. Hive can run on the HDFS and is best suited for data warehousing tasks such as extract, transform, and load (ETL), reporting, and data analysis. 
  • Flink: A stream-processing framework that provides robust capabilities for both batch and stream data processing, known for low latency and high throughput. 

Stream Processing Technologies 

Stream processing is based on continuous data streams. Data sources, such as sensors, generate a constant stream of data in a specific data format. The data stream consists of individual data or smaller packets with multiple data. How much data is filled into the packages can depend on time or quantity. Receivers such as analysis applications receive the data stream and process it. The most widely used software solutions include: 

  • Kafka: A distributed real-time processing platform handles trillions of events a day. It is used for building  data pipelines in real time and stream apps. An analytics company Swim found in its «State of Streaming Data» study that nearly half of companies generate insights from streams, with Kafka as the leading choice in terms of enabling technology. 
  • Flink: A powerful stream processing framework that provides low-latency data processing, stateful computations, and support for event time processing. 
  • Storm: A distributed real-time computation system that allows for the processing of unbounded data streams, ensuring reliability and scalability. 
  • Kinesis: An Amazon Web Services (AWS) service for real-time processing of streaming data at a massive scale, enabling application development for streaming data analytics. 

Practical examples of utilizing cloud-based data services include use cases across all industries, including real-time stock trading, minute-by-minute retail inventory management, social media feeds, multiplayer gaming, and ride-sharing apps. 

For example, when a passenger orders a ride through Lyft, real-time data streams unite to create a seamless user experience. Using this data, the application combines real-time location tracking, traffic statistics, pricing, and real-time traffic information to find the best possible driver for the passenger, calculate prices, and estimate the estimated arrival time at the destination based on both real-time and historical data.

Data Warehousing Solutions 

Data warehousing solutions are designed for storing and managing large volumes of structured and semi-structured data, optimizing query performance and analytics. Reliable data, especially when collected over time, helps users make smarter, more informed decisions about running their business.  

  • Redshift: A fully managed data warehouse service by AWS, offering fast query performance and scalability for handling large datasets. 
  • Snowflake: A cloud-based data warehousing platform that provides separate compute and storage scaling, automatic performance optimization, and secure data sharing. 
  • BigQuery: Google Cloud’s fully managed, serverless data warehouse that enables super-fast SQL queries using the processing power of Google’s infrastructure. 
  • Synapse Analytics: An integrated analytics service from Azure, combining big data and data warehousing, providing end-to-end analytics solutions. 

A data warehouse is inherently relational. This means that the structure or schema of the data is determined by predefined business and product requirements that are compiled, customized, and optimized for SQL query operations. Therefore, data warehousing solutions are best suited for storing data prepared for a specific purpose, such as data mining for BI analysis or obtaining data for an already identified business use case. 

For example, businesses can collect data from multiple structured sources across the organization, such as point-of-sale systems, websites, or email lists, and quickly retrieve and bring them together in one place for analysis and insights. 

Workflow Management Tools 

Workflow management tools orchestrate and automate complex workflow in the evolving data landscape, ensuring tasks are executed correctly and dependencies are managed. By automating routine processes, teams can focus on higher-impact projects instead of repetitive tasks and gain insight into workflows to identify opportunities. The most widely used tools include:

  • Airflow: An open-source tool to programmatically author, schedule, and monitor workflows, with a focus on creating data pipelines. 
  • Luigi: A Python package for building complex pipelines of batch jobs, handling dependency resolution, workflow management, and visualization. 
  • Oozie: A workflow scheduler system to manage Apache Hadoop jobs, supporting multiple types of Hadoop jobs and workflows. 
  • Prefect: A modern workflow orchestration tool that enables data engineers to build, monitor, and manage complex data workflows with ease and reliability. 

Workflow management software runs on data sources and a set of rules to process that data to reflect human activity. These workflow tools typically follow «if/then» statements and operate under the rule «if A occurs, then do B.» This rule-based logic system outlines the actions that should follow an event. This saves time and money and reduces the risk of human error.
