The Reality of Unstructured Data

Most data today isn’t neatly organized in tables. Instead, it comes as logs, emails, chat messages, API payloads, and sensor streams. This information is valuable, but doesn’t follow a set format, making it hard to search or analyze.

Logs are a great example. Every system emits them, from backend services to mobile apps. They hold clues about what’s happening, but those clues are hidden in blocks of raw text. Cloud storage makes it easy to save huge amounts of logs, but understanding them, especially in large volumes, remains complex. Whether you’re debugging, investigating outages, or tracking trends, unstructured data slows you down unless you have the right tools. 

As systems grow more distributed, unstructured data is the norm, not the exception.

Why Is Unstructured Data Hard for Observability?

At small volumes, you can search or filter logs with simple tools. But as data grows, things get complicated.

Inconsistency is the main problem. Logs come in many formats: JSON, plain text, or custom layouts. Even within a single app, log formats can vary wildly. Without a standard structure, machines can’t easily process or categorize this information.

Most tools expect data to be structured. They need clean fields and predictable formats. When data doesn’t fit, the tools break or require heavy engineering work to transform and clean it. At scale, you're dealing with millions of log lines per minute across dozens of services. Even small inconsistencies start causing big problems.

Unstructured data at scale is hard not because it’s unreadable, but because most tools aren’t built for its volume and variety. Teams end up fixing pipelines instead of using the data. 

What “At Scale” Really Means

Handling unstructured data at scale brings new challenges:

• More Sources: Modern environments have hundreds of microservices, APIs, and tools, each logging data in its own way.
• More Volume: Even small logs add up quickly. Every request can generate dozens of lines, leading to massive datasets.
• More Diversity: Logs can be structured, messy, nested, or missing context. There’s rarely a single schema.
• More Urgency: You often need to debug issues or investigate incidents in real time. Waiting for data to be processed isn’t an option.

This is the real cost of scale. It doesn’t just strain your infrastructure; it reveals the flaws in your tooling. Most platforms aren’t designed for messy, rapidly changing data. They assume structure, order, and predictability. At scale, that breaks.

To handle unstructured data effectively, your system must embrace the mess. That means:

• Storing raw logs as-is
• Structuring data only when you query
• Supporting schema drift and deeply nested formats

Only then can you get value from unstructured data, without constant rework or brittle pipelines.

What Most Tools Get Wrong

Most log tools expect strict formats. If your logs change or are inconsistent, these tools struggle. They require you to define fields, normalize formats, and pre-parse logs, adding delay and effort. Logs may be inconsistent, deeply nested, or completely unlabeled. Some are cleanly structured, while others are filled with multiline errors, stack traces, or malformed fields. Often, there's no common schema across services, just raw, unpredictable output. Traditional tools struggle with this kind of variety because they rely on predefined formats or schemas. When that structure is missing or breaks, so do the tools.

For example:

CtrlB’s Approach: Built for Unstructured Logs

CtrlB takes a different approach. It ingests raw logs without forcing a structure. This means you don’t have to clean or reformat your data first.

• Schema-less ingestion: Logs and traces are stored as-is.
• Micro-indexing: Fast, context-rich search, even over large datasets.
• On-demand structure: You can ask new questions of old data, even if formats have changed.

With CtrlB, you get sub-second results, regardless of data size or messiness, and it adapts to your data, not the other way around.

Soon, CtrlB will also support time-series, vector, and semantic search, all from one engine. This will let teams analyze trends, cluster events, and explore patterns without switching tools or rewriting pipelines.

Conclusion: Stop Fighting the Mess

Your data will never be perfect, and that’s okay. The right system doesn’t expect structure. It finds meaning when you need it, no matter how your data looks.

CtrlB turns chaos into clarity without extra work from your team. Instead of forcing data into rigid molds, it adapts to real-world messiness. That’s how modern observability should work: by surfacing insight from chaos, not by demanding perfect data.

In the real world, data is never clean. But your understanding of it can be.
