Data Lakes Are Not Just For Big Data - DZone Big Data

We recently wrote an article debunking common myths about data lake architectures, data lake definitions, and data lake analytics. It is called "What is a Data Lake_? Get A Leg Up Avoiding The Biggest Myths." _In that article, we framed the current conversation about data lakes and how they fit within enterprise data strategies. This topic has historically been confusing and opaque for those wanting to get value from a data lake due to conflicting advice from consultants and vendors.

One area that can be particularly confusing is the perception that lakes are only for “big data.” If you spend any time reading materials on lakes, you would think there is only one type and it would look like the Capsian Sea (it’s a lake despite “sea” in the name). People describe data lakes as massive, all-encompassing entities, designed to hold all knowledge. The good news is that lakes are not just for “big data” and you have more opportunities than ever to have them be part of your data stack.

Yes, There Are Different Types of Data Lakes

Just as they do in nature, lakes come in all different shapes and sizes. Each has a natural state, often reflecting ecosystems of data, just like those in nature reflect ecosystems of fish, birds, or other organisms.

Unfortunately, the “big data” angle gives the impression that lakes are only for “Caspian” scale data endeavors. This certainly makes the use of data lakes intimidating. As a result, describing things in such massive terms makes the concept of a lake inaccessible to those who can benefit from them on a smaller scale. Here are a few data lake examples;

• **The Great “Caspian”: ** Just like the Caspian is a large body of water, this type of lake is a large, broad repository-diverse set of data. This broad collection of diverse data reflects information from across the enterprise. This is how most data lake efforts are framed.
• **Temporary “Ephemeral”: **Just like deserts can have small, temporary lakes, an Ephemeral exists for a short period of time. They may be used for a project, pilot, PoC or a point solution and they are turned off as quickly as they were turned on.
• **Domain “Project”: **These lakes, like Ephemeral data lakes, are often focused on specific knowledge domains. However, unlike the Ephemeral lake, this lake will persist over time. These may also be “shallow,” meaning they may be focused on a narrow domain of data such as media, social, web analytics, email, or similar data sources.

We recently worked with a customer to create a “Domain” type lake. This lake would hold Adobe event data to an AWS to support an enterprise Oracle Cloud environment. Why AWS to Oracle? It was an efficient and cost-effective data consumption pattern for the customer Oracle BI environment, especially considering the agility and economics of using an AWS lake and Athena as the on-demand query service for lake content.

By design, all types of lakes should embrace an abstraction that minimizes risk and affords you greater flexibility. Also, they should be structured for easy consumption independent of their size. This ensures a lake used by a data scientist or business user or analyst all have an environment structured for easy data consumption.

Getting Started With Data Lakes

Being a successful early adopter means taking a business value approach rather than a technology one. Here are a few tips as you think about how to get started:

• Focus: Seek opportunities where you can deploy an “Ephemeral” or “Project” solution. This will ensure you reduce risk and overcome technical and organizational challenges so your team can build confidence with lakes.
• Passion: Make sure you have an “evangelist” or “advocate” internally, someone who is passionate about the solution and adoption within the company.
• Simple: Embrace simplicity and agility, put people, processes, and technology choices through this lens. The lack of complexity should not be seen as a deficiency but a byproduct of thoughtful design.
• Narrow: Keep the scope narrow and well defined by limiting your lake to understand data, say exports from ERP, CRM, Point-of-Sales, Marketing, or Advertising data. Data literacy at this stage will help you understand workflow around data structure, ingest, governance, quality, and testing.
• Experiment: Pair your lake with a modern BI and analytics tools like Tableau, Power BI, Amazon Quicksight, or Looker. This will allow non-technical users an opportunity to experiment and explore data access via a lake. This allows you to engage a different user base that can assess performance bottlenecks, discover opportunities for improvements, possible linkages to any existing EDW systems (or other data systems), and additional candidate data sources.

Getting Started With Data Lakes

Frameworks for Efficient Enterprise Analytics

The opportunities big data offers also come with very real challenges that many organizations are facing today. Often, it’s finding the most cost-effective, scalable way to store and process boundless volumes of data in multiple formats that come from a growing number of sources. Then organizations need the analytical capabilities and flexibility to turn this data into insights that can meet their specific business objectives.

This Refcard dives into how a data lake helps tackle these challenges at both ends — from its enhanced architecture that’s designed for efficient data ingestion, storage, and management to its advanced analytics functionality and performance flexibility. You’ll also explore key benefits and common use cases.

Introduction

As technology continues to evolve with new data sources, such as IoT sensors and social media churning out large volumes of data, there has never been a better time to discuss the possibilities and challenges of managing such data for varying analytical insights. In this Refcard, we dig deep into how data lakes solve the problem of storing and processing enormous amounts of data. While doing so, we also explore the benefits of data lakes, their use cases, and how they differ from data warehouses (DWHs).

Data Lake and Data Mesh Use Cases

As data mesh advocates come to suggest that the data mesh should replace the monolithic, centralized data lake, I wanted to check in with Dipti Borkar, co-founder and Chief Product Officer at Ahana. Dipti has been a tremendous resource for me over the years as she has held leadership positions at Couchbase, Kinetica, and Alluxio.

Definitions

• A data lake is a concept consisting of a collection of storage instances of various data assets. These assets are stored in a near-exact, or even exact, copy of the resource format and in addition to the originating data stores.
• A data mesh is a type of data platform architecture that embraces the ubiquity of data in the enterprise by leveraging a domain-oriented, self-serve design. Mesh is an abstraction layer that sits atop data sources and provides access.

According to Dipti, while data lakes and data mesh both have use cases they work well for, data mesh can’t replace the data lake unless all data sources are created equal — and for many, that’s not the case.

Data Sources

All data sources are not equal. There are different dimensions of data:

• Amount of data being stored
• Importance of the data
• Type of data
• Type of analysis to be supported
• Longevity of the data being stored
• Cost of managing and processing the data

Each data source has its purpose. Some are built for fast access for small amounts of data, some are meant for real transactions, some are meant for data that applications need, and some are meant for getting insights on large amounts of data.

AWS S3

Things changed when AWS commoditized the storage layer with the AWS S3 object-store 15 years ago. Given the ubiquity and affordability of S3 and other cloud storage, companies are moving most of this data to cloud object stores and building data lakes, where it can be analyzed in many different ways.

Because of the low cost, enterprises can store all of their data — enterprise, third-party, IoT, and streaming — into an S3 data lake. However, the data cannot be processed there. You need engines on top like Hive, Presto, and Spark to process it. Hadoop tried to do this with limited success. Presto and Spark have solved the SQL in S3 query problem.

Your Data Architecture: Simple Best Practices for Your Data Strategy

If you accumulate data on which you base your decision-making as an organization, you should probably think about your data architecture and possible best practices.

If you accumulate data on which you base your decision-making as an organization, you most probably need to think about your data architecture and consider possible best practices. Gaining a competitive edge, remaining customer-centric to the greatest extent possible, and streamlining processes to get on-the-button outcomes can all be traced back to an organization’s capacity to build a future-ready data architecture.

In what follows, we offer a short overview of the overarching capabilities of data architecture. These include user-centricity, elasticity, robustness, and the capacity to ensure the seamless flow of data at all times. Added to these are automation enablement, plus security and data governance considerations. These points from our checklist for what we perceive to be an anticipatory analytics ecosystem.
