Indexing: 2 real scaling case studies
2 of the 73 engineering write-ups in our database are tagged with the technique "indexing". They come from 2 companies (Axiom and Datadog) and were published between 2024 and 2025. Stack that shows up most often in these stories: Rust (2). 1 of the 2 state concrete scale numbers, for example "178.6 billion rows/sec" (Axiom). Each card below links to our short summary and the original post.

Haydex: From Zero to 178,600,000,000 rows a second in 30 days
Axiom turned a failed filter-index prototype into a production system for its event store, letting queries skip data and scan 178.6B rows per second.
Datadog · 2024
Timeseries indexing at scale
Datadog redesigned its timeseries indexing to handle a large jump in ingested data.
