Data Lake Management Made Easy: Top 8 Best Practices for High Performance

If you’re reading this, chances are you’re looking to utilize the full potential of your Data Lake. Nevertheless, as you may have already noticed, having a Data Lake alone isn’t sufficient. You must put into action Data Lake best practices that can assist you in efficiently managing and utilizing your Data Lake if you want to achieve high performance and gain valuable insights from your data.

In this blog, we’re going to discuss the top 8 Data Lake best practices for high-performance Data Lakes.  But, these Data Lake best practices aren’t just for data experts. They are for anyone who wishes to maximize their investment in a Data Lake. These best practices will assist you in driving business growth and making data-driven decisions whether you’re a business owner, analyst, or data scientist.

What is Data Lake and Why is it Good?

A Data Lake is a large repository of raw, unstructured, or semi-structured data which means data can be kept in a more flexible format for future use. Unlike hierarchical data warehouses, which organize data into files and folders, Data Lakes store data using object storage and metadata tags, making it easier to locate and retrieve data across regions.

Data Lakes are great because they are flexible, scalable, and cost-effective. Storing data in its native format reduces the cost of data transformation and processing, making it more cost-effective than traditional data warehouses.

Additionally, Data Lakes are highly scalable and allow for real-time data analysis, leading to faster and more informed decision-making. To fully benefit from a Data Lake, it should serve as a centralized repository for both structured and unstructured data, while also allowing for easy access to relevant data sources for various analytic use cases. Following best practices for ingestion, storage, and management is essential for optimal Data Lake performance. Learn more about Data Lakes and Data Lake Platforms in our previous blog.

8 Data Lake Best practices for High Performance

• Importance of Early Data Ingestion in Data Lakes

The procedure of gathering or absorbing data into object storage is known as data ingestion. Unlike traditional data warehouses, Data Lakes allow for the storage of semi-structured data in its native format, making ingestion simpler.  To ensure proper data storage and convenient access in the future, it is crucial to plan for data ingestion in advance. Effective data ingestion can also solve practical issues like processing streaming event data with an exactly-once strategy and optimizing storage for analytical performance. Check out our dedicated blog on Best Practices for Data Lake Ingestion to improve your Data Lake strategy.

• Data Lake Architecture

A solid Data Lake strategy includes a well-designed Data Lake architecture to achieve high performance. It should include key components such as data ingestion, storage, processing, governance, security, quality, and visualization. These components work together to ensure that data is ingested, stored, processed, and accessed in a secure and efficient manner. Proper design and implementation of these components can help organizations unlock the full potential of their Data Lake investment and achieve valuable insights from their data.

• Retention Policy

Having a retention policy in place for your Data Lake is crucial to avoid storing unnecessary data that may pose a regulatory risk or incur unnecessary costs. Regulatory requirements, such as GDPR, may necessitate deleting personally identifiable information after a certain period. Moreover, storage costs can quickly escalate if you store vast amounts of data. To implement your retention policy, you must be able to identify data that needs to be deleted and locate it in your object storage layer. This will not only help to reduce storage costs but also ensure compliance with regulations.

• Data Security

Implementing strong security measures is crucial to safeguarding sensitive data from unwanted access, breaches, and cyber-attacks.   Using role-based access control, which can restrict access to sensitive data and make sure that only authorized people can access it, is one of the finest data security strategies. Encrypting data can also shield sensitive information from hacks, breaches, and unwanted access. Monitoring and auditing data access is essential to identifying and preventing unwanted access as well as guaranteeing compliance with legal obligations.

Data masking is another best practice that can be used to protect sensitive data by hiding it from unwanted users. Finally, adding a second layer of protection to prevent unwanted access can be accomplished by adopting multi-factor authentication. By implementing these best practices, Data Lake owners can help to ensure the security of their data and protect it from potential threats.

• Data Partition

Partitioning your data is a useful technique that can help optimize the performance and reduce the cost of querying data in your Data Lake. Partitions are logical entities mapped to folders on storage platforms such as Amazon S3. Data is commonly partitioned based on timestamps such as hourly, daily, or minute-wise. The size of the partition depends on the type of queries being run. For instance, if queries require data from the last 12 hours, hourly partitioning should be used rather than daily, which would scan more data.

Partitioning also enables efficient data retrieval for different use cases, such as analytical queries, reporting, or machine learning. Organising Data facilitates analysis, resulting in quicker insights and more precise outcomes. Partitioning also offers a mechanism to quickly load, update, and remove data within particular partitions without affecting the rest of the data, which can help in data processing and administration.

• Right File Format

Storing data for analytics in a format that is optimized for reads, such as Apache Parquet or ORC, makes it easy to read and analyze. These open-source file formats can be read by various analytical services. It’s worth noting that compressed data needs to be decompressed before reading, so it’s important to choose compression that is not too strong to avoid wasting computing resources. While compression can save costs, choosing the right level of compression is crucial to avoid any negative impact on performance.

• Data Processing

Data processing is the crucial step of transforming, analyzing, and combining data in a Data Lake. To ensure efficient processing, it’s recommended to use distributed computing technologies like Apache Spark, which can speed up data processing. Parallel processing techniques can also speed up data processing, along with caching frequently accessed data to improve query performance. Finally, using columnar storage can reduce the amount of data accessed and improve query performance. By adopting these best practices, you can optimize your data processing and ensure faster and more efficient analytics.

• Data Governance

Data Governance is crucial for managing the availability, usability, integrity, and security of data in the Data Lake. Best practices include defining data policies and standards, implementing metadata management and data lineage, using data catalogs, and establishing data stewardship. These practices can help ensure proper management of the Data Lake, improve data quality, and maintain data security.

Additionally, access control tools such as Amazon’s Lake Formation and tokenization can be used to address concerns over unstructured data repositories. By implementing these measures, organizations can take advantage of the flexibility and scalability of a Data Lake while maintaining control over their data.

Wrap-Up

A Data Lake can help organizations efficiently manage and utilize their data for better decision-making and growth. Following best practices for ingestion, storage, management, and processing is essential to fully leverage its benefits. These 8 best practices include early planning, proper file format, and effective data processing. By implementing these best practices, organizations can ensure that their Data Lake is secure, efficient, cost-effective, and capable of providing valuable insights for various use cases. Remember that a well-designed Data Lake architecture, retention policy, and data security measures are crucial for the success of your Data Lake.

Overall, implementing these best practices requires planning, expertise, and a continuous effort to improve and maintain your Data Lake. Nevertheless, the benefits of having a high-performance Data Lake can outweigh the challenges, and the insights gained can lead to better business outcomes and competitive advantages in today’s data-driven world.
