Data Lake – Architecture, Solutions & Best Tools Explained
Introduction: Why Data Lake Matters Today
In a world increasingly dominated by digital, it’s no secret that business generates an overwhelming amount of structured and unstructured data. Effectively harnessing and analyzing all of this data is essential to driving innovation and customer-centricity, as well as supporting effective decision-making processes. While traditional databases limit volumes and formats of data, a data lake stores terabytes (or more) of raw data for future processing and analytics.
What is a Data Lake?
A data lake is a single storage location to store all the various types of data – structured, semi-structured, and unstructured – and at any dimension, all at one place. It can accept any type of data at its raw format, and as opposed to a pre-defined schema like a data warehouse, solution allows for an organization to ingest its data, and then structure it at a later time, when it is most needed.
The main advantages of data lake, include:
– Large data storage at a comparatively low cost
– Acceptance of all means of data (CSV, JSON, video, logs, IoT streams)
– Cloud, or on-premises scalability
– Flexibility for AI, machine learning, and advanced analytics
Simply put, if your business handles large and diverse data sets,It is a solution that can provide the agility and scalability required to turn that data into insights.
Data Lake vs Data Warehouse: What’s the Difference?
One of the most frequently asked questions we get is: what is the difference between a data warehouse and a data lake? Although they sound similar, they have remarkably different use cases.
Key Differences:
The data
– Data Lake – Able to store raw, unstructured, and structured data of the highest quality.
– Data Warehouse – Able to store structured, processed, and cleaned data.
The schema
– Data Lake – This means that it follows a schema on read (the data is structured when you access it).
– Data Warehouse – This means that it follows a schema on write (the data is structured before its stores).
Use case:
– Data Lake – This use case is best for data that is going to be used for AI, machine learning, or big data analytics.
– Data Warehouse – This use case is best for reporting, BI dashboards, or historical analysis.
Cost & scalability :
– Data Lakes – provided higher returns on investment and capacity to scale.
– Data Warehouses – hence a more traditional approach in processing cost and performance optimization.
In short, if you are managing your data lake vs data warehouse choice, it boils down to what your organization values most – real time innovation vs structured reporting.
Data Lake Architecture Explained
It is important to understand the architecture of a data lake to be successful. Although there are different architectures , in general it is comprised of four main layers:
Ingestion Layer – The first one is the ingestion layer, which is responsible for ingesting the raw inputs from multiple sources (web and mobile applications, different types of databases, IoT devices, social applications, and any other source).
Storage Layer – After the data is ingested it is stored as is (raw) or transformed (structured or unstructured), in the storage layer on local clusters or cloud storage.
Processing Layer – After the storage layer, the data is transformed, cleaned, and/or enriched into a useful dataset for advanced analytics in the processing layer.
Consumption Layer – This last layer is where the users query, visualize, or analyze the data through various business intelligence tools, dashboard visualizations, or AI models.
Modern tools provide native integration with machine learning platforms, so that organizations can build predictive models on top of the data lake data.
Delta Lake vs Data Lake: What’s the Difference?
Another important and interesting comparison is :
– Data lake: Store everything, limited consistency, lower transaction support.
– Delta lake: Enhanced storage layer that is built on top of a basic data lake. Delta lakes include features such as ACID transactions, data schema enforcement, time travel queries and checkpoints.
