The challenges of data engineering

With the growing need to handle and process huge amounts of data, Big Data Engineer skills are becoming a must-have. Not long ago, even the thought of storing and manipulating large-scale data warehouses would send chills down the companies’ spines.

But some functional challenges remain on the road to managing such vast amounts of rapidly growing data. Let’s understand some of these bottlenecks in brief.

Metadata

It is common knowledge that with the growing volume and variety of data, organizing it into handleable parts is quite a tall task. This is when a need for an added layer of information, conceptually known as data about the data or metadata, arises.

There are multiple prominent pieces of information like data sources, time of updates, description of schema, and other useful tidbits. These act as guides for large data pools and help navigate through them.

Data security 

Since data is increasing exponentially, security is bound to be compromised in the long run. The variety of data coming from different sources in different pipelines makes it susceptible to hackers’ attacks, leading to sensitive information being leaked. 

This acts as one of the roadblocks to data engineers getting access to use the data due to the vulnerability that clouds it. Additional security touchpoints and leveraging cloud platform security protocols are the main ways to ensure the security and integrity of data. 

Machine Learning and predictive analytics have often been leveraged to track and prevent attacks.

Multiple data sources

Real-time data is pouring in at lightning-fast speeds and in massive volumes. Handling this data from different software and platforms and bringing it to a common standard that can be used for further processing is a bigger challenge than it seems. 

Virtual data warehouses have popped onto the scene with their ability to connect data from different locations and consolidate it in a dedicated cloud-based repository. Such methodical storage leads to actionable insights from the data that can be credibly deployed to solve business problems.

Data quality

Data in its truest form is messy and hard to understand. It has to go through an entire cleaning pipeline before it can be processed and fed to machine learning models.

Poorly curated data is a huge concern in data science and data engineering, as it affects the foundation of all other activities to follow.
