Article: Time-Series Storage: Design Choices That Shape Cost and Performance
Our take

The conversation around data infrastructure is shifting, and a recent piece by Nirmesh Khandelwal on time-series storage design captures exactly why. At a moment when organizations are pouring resources into AI platforms and next-generation hardware, articles like "Google unveils Googlebooks, a new line of AI-native laptops" remind us that the industry is racing toward increasingly capable systems. But as "Turning AI cost spikes into strategic growth opportunities" makes clear, all that compute potential means little if the underlying storage layer works against you. Khandelwal's article brings this principle into sharp, practical focus: the decisions you make about how data is physically laid out, compressed, and partitioned will shape your cost and performance outcomes far more than the database product you choose.
This is a counterintuitive claim, and that is exactly what makes it valuable. Most engineering teams spend considerable energy evaluating databases, comparing feature sets, and benchmarking vendors. Khandelwal argues persuasively that this emphasis is misplaced. Row layout determines how efficiently your queries scan data. Compression timing affects both storage costs and decompression overhead at query time. Partitioning strategy dictates whether your queries touch a manageable slice of data or an unwieldy monolith. These are not secondary concerns. They are the architecture itself, and getting them right on a well-understood platform like PostgreSQL can rival the performance of specialized systems, provided you design the storage layer with intention.
What makes this analysis especially useful is its commitment to measurability. Rather than presenting abstract principles, Khandelwal works through trade-offs using tools most teams already have access to, including PostgreSQL and Apache Parquet. This approach transforms the conversation from theoretical to operational. Readers can reproduce the experiments, adapt the patterns to their own workloads, and make decisions grounded in their own data rather than vendor claims. For teams navigating the complexity of time-series workloads, whether in monitoring, financial analytics, or IoT telemetry, this kind of first-principles thinking is not just helpful, it is essential. It empowers engineers to ask better questions before committing to expensive migrations or new platform investments.
There is also a broader lesson here that extends well beyond time-series systems. As data volumes grow and AI-driven workloads introduce new patterns of access and retention, the fundamentals of storage design will only become more consequential. Teams that understand the mechanics behind their data layer will be better positioned to adapt, optimize, and scale without constantly re-platforming. Those who default to chasing the newest database trend without examining these foundational choices may find themselves solving the wrong problem. The real question for anyone managing growing data assets is not simply which tool to adopt, but how deeply they understand the storage decisions that tool is making on their behalf. As infrastructure continues to evolve at a rapid pace, that understanding is what separates durable performance from perpetual rework.

Every time-series database makes a set of storage design decisions: how to lay out rows, when to compress, what to partition on. These decisions determine cost and query performance more than the choice of database itself. This article works through those fundamentals from first principles, using widely available tools like PostgreSQL and Apache Parquet to make each trade-off measurable.
