Big Data Pipeline Recipe

Introduction

If you are starting with Big Data it is common to feel overwhelmed by the large number of tools, frameworks and options to choose from. In this article, I will try to summarize the ingredients and the basic recipe to get you started in your Big Data journey. My goal is to categorize the different tools and try to explain the purpose of each tool and how it fits within the ecosystem.

First let’s review some considerations and to check if you really have a**Big Data problem**_. _I will focus on open source solutions that can be deployed on-prem. Cloud providers provide several solutions for your data needs and I will slightly mention them. If you are running in the cloud, you should really check what options are available to you and compare to the open source solutions looking at cost, operability, manageability, monitoring and time to market dimensions.

Data Considerations

(If you are a experience with big data, skip to the next section…)

Big Data is complex, do not jump into it unless you absolutely have to. To get insights, start small, maybe use Elastic Search and Prometheus/Grafana to start collecting information and create dashboards to get information about your business. As your data expands, these tools may not be good enough or too expensive to maintain. This is when you should start considering a **data lake or data warehouse; **and switch your mind set to start thinking big.

Check the volume of your data, how much do you have and how long do you need to store for. Check the temperature! of the data, it loses value over time, so how long do you need to store the data for? how many storage layers(hot/warm/cold) do you need? can you archive or delete data?

Other questions you need to ask yourself are: What type of data are your storing? which formats do you use? do you have any legal obligations? how fast do you need to ingest the data? how fast do you need the data available for querying? What type of queries are you expecting? OLTP or OLAP? What are your infrastructure limitations? What type is your data? Relational? Graph? Document?

I could write several articles about this, it is very important that you understand your data, set boundaries, requirements, obligations, etc in order for this recipe to work.

4Vs of Big Data

Data volume is key, if you deal with billions of events per day or massive data sets, you need to apply Big Data principles to your pipeline. However, there is not a single boundary that separates “small” from “big” data and other aspects such as the velocity, your team organization, the size of the company, the type of analysis required, the infrastructure or the **business goals **will impact your big data journey. Let’s review some of them…

OLTP vs OLAP

Several years ago, businesses used to have online applications backed by a relational database which was used to store users and other structured data(OLTP). Overnight, this data was archived using complex jobs into a **data warehouse **which was optimized for data analysis and business intelligence(OLAP). Historical data was copied to the data warehouse and used to generate reports which were used to make business decisions.

Data Warehouse vs Data Lake

As data grew, data warehouses became expensive and difficult to manage. Also, companies started to store and process unstructured data such as images or logs. With Big Data, companies started to create **data lakes **to centralize their structured and unstructured data creating a single repository with all the data.

Image for post

In short, a data lake it’s just a set of computer nodes that store data in a HA file system and a set of **tools **to process and get insights from the data. Based on Map Reduce a huge ecosystem of tools such Spark were created to process any type of data using commodity hardware which was more** cost effective**.The idea is that you can process and store the data in cheap hardware and then query the stored files directly without using a database but relying on file formats and external schemas which we will discuss later. Hadoop uses the HDFS file system to store the data in a cost effective manner.

For OLTP, in recent years, there was a shift towards NoSQL, using databases such MongoDB or Cassandra which could scale beyond the limitations of SQL databases. However, recent databases can handle large amounts of data and can be used for both , OLTP and OLAP, and do this at a **low cost for both stream and batch processing; **even transactional databases such as YugaByteDB can handle huge amounts of data. Big organizations with many systems, applications, sources and types of data will need a data warehouse and/or data lake to meet their analytical needs, but if your company doesn’t have too many information channels and/or you run in the cloud, a single massive database could suffice simplifying your architecture and drastically reducing costs.

Hadoop or No Hadoop

Since its release in 2006, Hadoop has been the main reference in the Big Data world. Based on the MapReduce programming model, it allowed to process large amounts of data using a simple programming model. The ecosystem grew exponentially over the years creating a rich ecosystem to deal with any use case.

Recently, there has been some criticism of the Hadoop Ecosystem and it is clear that the use has been decreasing over the last couple of years. New OLAP engines capable of ingesting and query with ultra low latency using their own data formats have been replacing some of the most common query engines in Hadoop; but the biggest impact is the increase of the number of Serverless Analytics solutions released by cloud providers where you can perform any Big Data task without managing any infrastructure.

Simplified Hadoop Ecosystem

Given the size of the Hadoop ecosystem and the huge user base, it seems to be far from dead and many of the newer solutions have no other choice than create compatible APIs and integrations with the Hadoop Ecosystem. Although HDFS is at the core of the ecosystem, it is now only used on-prem since cloud providers have built cheaper and better deep storage systems such S3 or GCS. Cloud providers also provide **managed Hadoop clusters **out of the box. So it seems, Hadoop is still alive and kicking but you should keep in mind that there are other newer alternatives before you start building your Hadoop ecosystem. In this article, I will try to mention which tools are part of the Hadoop ecosystem, which ones are compatible with it and which ones are not part of the Hadoop ecosystem.

Batch vs Streaming

Based on your analysis of your data temperature, you need to decide if you need real time streaming, batch processing or in many cases, both.

In a perfect world you would get all your insights from live data in real time, performing window based aggregations. However, for some use cases this is not possible and for others it is not cost effective; this is why many companies use both batch and stream processing. You should check your business needs and decide which method suits you better. For example, if you just need to create some reports, batch processing should be enough. Batch is simpler and cheaper.

Image for post

The latest processing engines such Apache Flink or Apache Beam, also known as the 4th generation of big data engines, provide a unified programming model for batch and streaming data where batch is just stream processing done every 24 hours. This simplifies the programming model.

A common pattern is to have streaming data for time critical insights like credit card fraud and batch for reporting and analytics. Newer OLAP engines allow to query both in an unified way.

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.
