TECHNOLOGY PROFILE · TECH-0297
whylogs
Data profiling library using compact statistical summaries.
Reference link only — not reviewed this edition. This profile preserves the prepared catalog’s original descriptions. Advantages depend on the workload; comparisons are editorial, not benchmark results.
Where it has an edge
Profiles large datasets without retaining every raw value in a monitoring system.
Best-fit problems
Dataset and feature observability where raw-data movement is undesirable.
Tradeoffs & cautions
Profiles can still leak information; summaries may miss rare or joint-pattern failures.
What to test before choosing
Inject failures and data shifts; verify useful alerts, observability cost and redaction of sensitive content.
