Simplyblock provides high-IOPS and low-latency Kubernetes persistent volumes for your demanding database and other stateful workloads.

Production-grade PostgreSQL on Kubernetes with Álvaro Hernández Tortosa from OnGres (interview)

Updated: 1 day ago

This interview is part of the Simplyblock Cloud Commute Podcast, available on Youtube, Spotify, iTunes/Apple Podcasts, Pandora, Samsung Podcasts, and our show site.


In this installment, we're talking to Álvaro Hernández Tortosa from OnGres, a company creating StackGres, a PostgreSQL operator to help operate PostgreSQL in a Kubernetes environment, as well as the Postgres ecosystem and why it is so hard to create a production-grade Postgres service.


Key Learnings


Why is high-performance disk access important to a database?


High-performance disk access is crucial for a database because it significantly affects the speed and efficiency of data retrieval and storage operations. Databases frequently read and write large amounts of data, and fast disk access reduces latency, ensuring quick query responses and high transaction throughput. This is especially important for maintaining performance under heavy loads, minimizing downtime, and supporting real-time data processing and analytics. Efficient disk access also helps in optimizing resource usage, reducing costs, and improving overall application performance and user experience.

Why is low latency disk access important to a database?


Low latency disk access is crucial to a database for several reasons:


1. Faster Query Responses: Low latency ensures that data retrieval and storage operations are quick, leading to faster query execution and improved application performance.


2. High Transaction Throughput: Reduces wait times for read and write operations, allowing the database to handle more transactions per second, essential for high-traffic applications.


3. Real-Time Processing: Critical for applications requiring real-time data processing and analytics, enabling timely decision-making and insights.


4. User Experience: Enhances the end-user experience by providing quick responses and minimizing delays in data-intensive applications.


5. Efficiency and Resource Utilization: Reduces bottlenecks, leading to more efficient use of computing resources and potentially lowering operational costs.


How can Simplyblock help with PostgreSQL optimization?


Simplyblock, as a storage solution, can help with PostgreSQL optimization in several ways:


  • Improved Storage Performance: Simplyblock offers optimized storage performance compared to traditional storage solutions in terms of latency and workloads. This can result in faster read and write operations for PostgreSQL databases, especially for large datasets or intensive workloads.

  • Data Compression: Simplyblock provides data compression techniques which can significantly reduce the amount of storage space required for PostgreSQL databases. This not only saves on storage costs but also improves I/O performance by reducing the amount of data that needs to be read from or written to disk.

  • Deduplication: By identifying and eliminating duplicate data, simplyblock can further optimize storage usage, ensuring that only unique data is stored. This can be particularly beneficial for PostgreSQL databases with redundant data.

  • Improved I/O Performance: Simplyblock's storage solutions are optimized for high I/O performance, which can translate to faster read and write operations for PostgreSQL databases. This is crucial for performance-critical applications where database speed is a key factor.

  • Caching: Simplyblock can utilize advanced caching mechanisms (host-local NVMe based near-caching) to store frequently accessed data in faster, host-local storage tiers, reducing the latency for read operations.

  • Scalable Storage: Simplyblock offers scalable storage solutions that can grow with your PostgreSQL database needs. This means you can start small and scale up as your data volume increases without worrying about running out of storage space.

  • Immediate Snapshots: Simplyblock provides a full copy-on-write block device, enabling immediate snapshots. While not an actual backup, snapshots can be a simple means to increase the resilience of a PostgreSQL database, ensuring data integrity, availability, and quick recovery in failure situations.


By leveraging simplyblock’s advanced storage capabilities, PostgreSQL databases can achieve better performance, lower storage costs, and greater scalability, making it a robust solution for businesses of all sizes.
