In the era of Big Data, these pipelines must provide not only accessibility and efficiency to data, but also high-throughput and scalability while maintaining low-latency. This article has gathered insights on how streamlining your Big Data architecture can help you meet these network requirements.
Why it is important:
Data pipelines are used to combine, process, and consolidate data into one system. While doing so, they need to achieve high throughput and low latency. Without these two metrics, valuable time and dollars are wasted.
This article will help you understand Big Data Pipelines by taking you through the following topics:
Big Data Pipeline
Big Data pipelines create a seamless flow of operations from the collection of data to its insightful application. Typical stages of the Big Data pipeline are:
Most efforts are gone in the collection, ingestion, and preparation stages—collectively known as data engineering.
The pipeline is triggered with data collection that involves the extraction of data from multiple sources, including websites, apps, devices, microservices, and analytics. Once the data is received, it is dropped into a data lake. The data is then cleaned—mostly using the extract, transform, load (ETL) approach—and catalogs in a ready-to-use format for data warehouse storage.
At data warehouses, several algorithms, including analytics, machine learning, or other data science procedures, are used for computation to deliver models and insights. Lastly, the insights obtained are delivered to the final users through dashboards, notifications, microservices, and other interfaces.
High-Throughput and Low-Latency
Big Data pipelines are measured by two primary metrics:
High-throughput: How much data can be transmitted from one place to another in a given time
Low-latency: Minimal to zero delays to produce outcome from the input
Meeting the requirement of high-throughput and low-latency is not easy. Pursuing these two metrics can bring up several challenges, creating trade-offs in other network characteristics affecting performance.
Several measures are taken to improve throughput, such as using Optimal Superframe and Data Buffer Scheme (OSDBS), parallelized decision-making, and RDMA. However, meeting high-throughput requirements also creates a few challenges:
Several methods are used to achieve low-latency. The most promising way is to divide your processing work between ingest and query time such that most work is managed during ingest, thus lowering latency. However, this can also make ingestion expensive. Moreover, reducing latency can affect other network characteristics like accuracy, which shouldn’t be compromised. Also, for your data to reach the destination faster, more bandwidth is consumed, which is another challenge.
Can we achieve high-throughput and low-latency without compromising other network characteristics? The answer is yes.
Monitoring endpoints that cause the most latency can help you understand and mitigate bottlenecks. However, this is only a half-baked measure. To bring a real transformation in your network performance, you need to create flexibility in your Big Data architecture, so your pipelines are aligned to meet the needs of high-throughput and low-latency.
Architectural Choices for Big Data Pipeline
Data lakes, warehouses, and the pipeline must be structured to make way for high-throughput and low-latency. A way to do this is by creating a balance between batch and stream processing during computation. This can be easily done in lambda architecture divided into three layers:
AWS has built a Well-Architected Review (WAR) framework to guide you on architectural best practices for high-performance data pipelines. It helped InterMiles, a travel and lifestyle reward program, align its architecture with the cloud best practices.

While building an architecture for big data, its components play a significant role in determining the level of performance your system will deliver. These components include Endpoints, Message Queue, Data Store, Infrastructure, Computer Engine, and ML Framework. While your endpoints, message queue, and storage capacity together influence the throughput of your network, computation and databases can influence its latency. Thus, the best way to achieve the desired levels of throughput and latency is to understand the role these components play and make the right choices in the selection of your tech stack to ensure the best performance.
|Architectural components||Technology choices|
|Endpoints||REST/MQTT end points are the most suitable protocols for Big Data applications|
|Message Queue||Kafka provides a high ingestion rate|
|Data Store||Hadoop HDFS data lakes and AWS S3 cloud storage provide high-volume storage at a low cost.|
|Query Infrastructure||Apache Hive is a popular language to convert data lakes into data warehouses.|
|Computes||Hadoop Map-Reduce and Apache Spark provide batch computer engines to deliver high-throughput, while Apache Storm, Flink, and Beam on a stream runner can help with latency needs.|
AWS, Microsoft Azure, and Google Cloud Platform (GCP) also offer serverless computing choices for Big Data architecture. In a serverless architecture, the codes run on containers, and for any storage requirements, communication is established with the backend.
Serverless analytics flow through four layers of the pipeline:
There are several benefits of serverless architecture:
Pursuing High-Throughput, Low-Latency Big Data Pipelines
High-throughput and low-latency pipelines create high customer satisfaction that brings high revenues. Organizations need to realize that these are not merely selective requirements but mandates considering the speed at which the digital world is growing today. You must design your architecture with these considerations of network performance if you want to keep up with your competition.
