With the massive amount of data generated daily, businesses must implement the best technologies to extract valuable insights and put them to use. Big data is now a core data science strategy that helps deal with enormous data sets and their computational analysis. As per recent reports, by 2028, the big data industry is expected to reach over USD 400 billion. 

Hadoop and Spark are widely used in big data because of their efficient data processing capabilities. These frameworks simplify building scalable systems to collect, store, transform, and utilize data and optimize business operations. They also support advanced analytics.

So, what are Hadoop and Spark? How can you build efficient data pipelines with Hadoop and Spark? Read on to find out. 

What are Hadoop and Spark?

Apache Hadoop can manage huge data sets and uses simple programming models for distributed processing. There are no format requirements since it deals with structured, unstructured, and even semi-structured data. Since it uses nodes (computer networks), Hadoop breaks down complex jobs into parallel-running smaller workloads. Thus, it allows rapid data access across multiple servers. 

Apache Spark also supports huge-scale data transformations and analyses at a faster speed. It is a multi-language data processing engine and facilitates development APIs in Java, R, Scala, and Python. It can also reuse data with in-memory cache and thus handles iterative workloads effectively. Spark is based on the RDD (Resilient Distributed Dataset) structure, which is the key to its lightning-fast speed.

Building Efficient Data Pipelines with Hadoop and Spark

Raw data cannot be used directly and needs to be organized, transformed, and moved across different phases for business intelligence and analysis. Data pipelines help aggregate information from diverse sources, reformat and process the available information, and store it in a data repository for better usability. Thus, it breaks down data silos and enables seamless information flow without inconsistencies. 

Modern data pipelines eliminate most manual steps with automation. This reduces the workload considerably and increases the breadth and scope of data usage. They are resilient structures that can scale as per growing data needs. Also, efficient data pipelines aid in real-time analytics, which is essential for informed decision-making.

Here’s how you can use Hadoop and Spark for data pipelines:

Defining Goals

It is important to assess the business requirements and define the goals and objectives of the pipelines. Some common types are batch processing, real-time data, and cloud-native data pipelines. You can decide whether Spark or Hadoop will cater the best based on your needs. For instance, Spark can create a robust framework that provides speed and flexibility if you want real-time results. If you want distributed batch processing on a budget, choose Hadoop.  

Optimizing Design

An efficient data pipeline has these key components: Data Ingestion, Data Storage, Data Processing, and Data Output. You can choose Spark or Hadoop or adopt a hybrid model for these components. Spark is ideal for data collection if you are dealing with interactive loads and want to design a user-friendly model. Hadoop can help you with linear data processing, while Spark is suitable for low-latency data processing. For secure data storage, choose Hadoop because it has advanced features.

Choosing Right Technologies

Based on the data type, structure, size, and velocity, you should choose the right technology that fits your requirements seamlessly. Also, as business needs keep changing with time, it is essential to prioritize scalable architectures. Besides, the designed pipeline should integrate into your existing infrastructure without causing any issues. For instance, if your workload is based on Machine Learning algorithms, then Spark has in-built libraries. However, Hadoop needs external libraries for this. 

Data Quality and Integrity

Data quality and consistency are crucial to developing efficient data pipelines. No matter what framework you use, Hadoop or Spark, maintaining high-quality data without inconsistencies and errors can yield better outcomes. Try data cleansing, reformatting, validation, and other such techniques. Besides, you can implement quality checks, define strict standards, and establish rules and procedures for data governance to ensure there’s no compromise in the data quality and accuracy.

Final Words 

Hadoop and Spark can adeptly handle massive datasets and unlock their true potential. They have their advantages and can also be combined for maximum benefits. Therefore, you must learn these technologies in detail to use them for building efficient data pipelines.
