Publisher review
Imply Lumi, launched in September 2025 by the original creators of Apache Druid, is marketed as the industry's first Observability Warehouse. It is a high-performance, cost-efficient data layer designed for observability and security teams that need to retain more telemetry data, accelerate investigations, and reduce costs without replacing their existing monitoring tools. The product targets organizations using Splunk, Grafana, Tableau, or AI assistants like Claude and Langchain, offering a way to decouple data storage from visualization and analysis layers. By plugging into current stacks with zero disruption, it appeals to teams burdened by legacy systems, expanding telemetry volumes, and vendor lock-in, enabling them to store years of full-fidelity data and make it instantly searchable across multiple tools.
Imply Lumi ingests data from any source using existing agents and forwarders, such as Splunk Universal Forwarders, Heavy Forwarders, and OpenTelemetry, via S2S or S3 protocols, requiring no custom agents or pipeline rewrites. Its proprietary high-efficiency storage format delivers 2–5x better compression compared to traditional formats, reducing storage costs by over 70% according to Imply's claims. The Druid-powered query engine enables queries that are 10x faster, supporting high concurrency and interactive search speeds. Data remains 'always hot' with no cold storage delays or rehydration needed, and the platform supports schema on persist for flexible indexing. Federated search within Splunk allows teams to run native SPL queries from the Splunk UI or API, preserving existing dashboards, alerts, and workflows. The system also feeds long-term datasets directly into AI, ML, and anomaly detection tools without additional preparation or duplication.
Imply Lumi competes directly with traditional observability platforms like Splunk, Grafana, Tableau, and AI assistants such as Claude and Langchain. Its key differentiator is the decoupling of storage from tooling, allowing organizations to keep their existing interfaces while gaining cost and performance benefits. As a member of the Splunk Partnerverse, Imply positions Lumi as an extension rather than a replacement for Splunk deployments, contrasting with vendors that require full stack migrations. However, it faces competition from open-source alternatives like Elastic and from cloud-native observability suites that offer integrated storage and querying. Imply's backing by investors including a16z, Bessemer Venture Partners, and Thoma Bravo provides financial credibility, but the product is new and lacks extensive third-party validation.
Honest trade-offs include the product's novelty: launched in 2025, it has limited public customer references or independent performance benchmarks, making claims of 70% storage reduction and 10x faster queries unverified outside vendor materials. The dependency on Apache Druid, while performant for time-series data, may not suit all observability workloads, particularly those requiring complex relational joins or unstructured log parsing. Pricing, starting at $100/month for a Starter plan and scaling to $4.20/hour for larger environments, is usage-based but can become unpredictable for high-volume telemetry ingestion. Additionally, while Lumi integrates with Splunk via federated search, it adds a new layer to the stack, potentially increasing operational complexity for teams that prefer a single-vendor solution.

-
Usage-based pricing
Pay only for data used, with no filters or prepayments, starting at $100/month for the Starter plan.
Strengths and trade-offs
Strengths
- Reduces storage costs by over 70% using a proprietary format with 2–5x better compression than traditional formats.
- Enables 10x faster queries via a Druid-powered engine, accelerating investigations and reducing mean time to resolution.
- Integrates with existing Splunk deployments through federated search, allowing native SPL queries without workflow changes.

- Requires adding a new data layer to the stack, increasing operational complexity for teams preferring single-vendor solutions.
- Pricing is usage-based and can become unpredictable for high-volume telemetry ingestion, despite starting at $100/month.
- Dependency on Apache Druid may not suit workloads requiring complex relational joins or unstructured log parsing beyond time-series data.
Pricing context
Flexible, usage-based pricing with a Starter plan at $100/month, higher plans from $600/month to $4.20/hour for larger environments.
Getting started with Lumi
-
Sign up for Lumi
Go to the Imply Lumi website and create an account. Choose the Starter plan at $100/month or a higher plan based on your expected data volume. Complete the registration and verify your email to activate the account.
-
Connect your data sources
Configure your existing agents, such as Splunk Universal Forwarders or OpenTelemetry collectors, to send telemetry data to Lumi via S2S or S3 protocols. No custom agents or pipeline changes are needed; just point your forwarders to the Lumi endpoint.
-
Set up federated search in Splunk
Install the Lumi federated search app from Splunkbase. Configure the connection between your Splunk instance and Lumi by providing the API endpoint and credentials. This allows you to run native SPL queries from the Splunk UI against Lumi-stored data.
-
Run your first query
Open the Splunk search bar or Lumi's query interface. Enter a native SPL query to search across your telemetry data stored in Lumi. Observe the fast, interactive results powered by the Druid engine, with no cold storage delays.
-
Monitor usage and costs
Access the Lumi dashboard to track your data ingestion volume and query activity. Review the usage-based billing metrics to ensure costs align with your budget. Adjust ingestion filters or plan limits as needed to control spending.
