TL;DR: Federated search makes retained data queryable without first building a new index, according to Query, while index-first designs still force teams to pre-pay for speed and schema decisions. For practitioners, the control question shifts from how much to ingest to where each data source should live and be searched.
Editorial analysis by NHI Mgmt Group, based on content published by Query: “Where the Index Lives”.
Key questions
Q: When should security teams use a column store instead of a log index?
A: Security teams should use a column store when the main workload is analytical queries across many rows but only a few fields, such as aggregation, reporting, and long-range trend analysis.
Q: How do index-first search engines handle security logs?
A: An index-first search engine stores security logs in an index optimised for querying, so analysts can filter by fields such as host, user, event type and time without scanning raw files each time.
Practitioner guidance
- Define search tiers by workload shape Place rare-indicator hunts, scheduled detections and historical analytics on different retrieval paths instead of forcing one architecture to handle all three equally well.
- Keep identity and security systems queryable in place Preserve direct query access to identity providers, EDR consoles, ticketing platforms and SaaS audit logs so investigations do not depend on export pipelines.
- Separate index decisions from retention decisions Choose whether a dataset should be indexed based on query frequency and analytical shape, not simply because it must be retained for compliance.
Bottom line: Federated search changes security data architecture by reducing the need to prebuild and store indexes for every retained source.

Federated search is a governance decision about where security truth lives. Once a platform copies every source into its own index, it also becomes the place where retention cost, schema assumptions and query shape are controlled. That can simplify hunting, but it centralises operational risk and creates a standing obligation to keep the index current. Practitioners should treat search architecture as a control plane decision, not just a performance choice.
A few things that frame the scale:
- 28.65 million new hardcoded secrets were detected in public GitHub commits in 2025 alone, a 34% year-over-year increase and the largest single-year jump ever recorded, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: When should security teams use a column store instead of a log index?
A: Security teams should use a column store when the main workload is analytical queries across many rows but only a few fields, such as aggregation, reporting, and long-range trend analysis. Use a log index when the priority is fast event retrieval, full-text search, and low-latency investigation across semi-structured security logs.
