Zettabyte
A zettabyte (ZB) is a unit of data equal to 10²¹ bytes.
It's an executive-friendly concept to justify retrieval, indexing, compression, and governance rather than brute-force "more context."
Explanation
It's used to describe extremely large-scale datasets—useful for communicating why architecture matters: you can't "stuff everything into context," even with long windows.
Marketing Relevance
It's an executive-friendly concept to justify retrieval, indexing, compression, and governance rather than brute-force "more context."
Example
"We have zettabytes of enterprise knowledge—so we retrieve only what's relevant and approved for this user and question."
Common Pitfalls
Using it as hype without connecting to real constraints (cost, latency, risk).
