Common Challenges

Data Security and Access: Misalignment between data security initiatives and data access controls can leave organizations vulnerable to data leaks, breaches, and insider threats. Securing data with appropriate access rights is a major challenge, with over 50% of data engineers reporting it as one of their biggest issues. Scalability of Data Access Policies: Traditional role-based access control (RBAC) policies are not scalable, leading to role explosion and the need for manual maintenance of numerous hyper-specific policies. This burden results in data engineers spending significant time managing data access issues. Data Quality: Poor data quality can lead to inaccurate insights and decisions. Factors contributing to poor data quality include human error, system errors, and data drift. Implementing data quality metrics, checks, and using data profiling tools can help improve data quality. Data Scalability: The ability of a system to handle increasing amounts of data without affecting performance is a critical challenge. The volume of data is constantly growing, and factors such as the type of data, size of data, and system architecture affect scalability. Data Integration: Integrating data from different sources into a single, consistent dataset is complex due to data silos, different formats, and schemas. This process consumes a significant amount of time, with 80% of time spent on data discovery, preparation, and protection rather than on actual analytics. Data Security: Protecting data from unauthorized access, use, disclosure, disruption, modification, or destruction is crucial. Human error, system vulnerabilities, and malicious attacks are key factors contributing to data security problems. Talent Shortages and Skills Gap: There is a growing gap between the supply of qualified candidates and the skills demanded by data engineering. The increasing complexity of data science tasks and the rising demand for data-driven decision-making exacerbate this issue. High Costs and Resource Constraints: Data engineering teams often face high costs associated with tools and personnel. The expense of data tools can range from $50,000 to $1 million per year, in addition to the salaries of data engineers. Burnout and Workload: The workload on data engineers is significant, with many feeling burnt out due to the lack of resources and the burden of managing data access and security. Only a small percentage of companies invest in automated data access tools to alleviate this load. Decentralization and Automation: Trends such as data mesh and the rise of AI could transform the role of data engineers, potentially reducing their autonomy and strategic involvement. Data engineering tasks might become more automated, shifting the focus towards infrastructure maintenance and support roles. Addressing these challenges requires a multifaceted approach, including streamlining data access and security processes, adopting automated data security platforms, improving data quality, enhancing scalability, and investing in the development of data engineering skills.
