openobserve-api-http

openobserve-api-http is the HTTP transport composition root for OpenObserve. It composes the independent API crates, routers, OpenAPI schemas, and rate-limit path mappings used by the server binary.

HTTP handlers are grouped into four business-domain crates:

• openobserve-api-ingest for log, metric, trace/OTLP, RUM, and cluster ingestion.
• openobserve-api-search for search, log pattern extraction, PromQL, trace query, saved-view, and search-job APIs.
• openobserve-api-pipelines for pipelines, functions, enrichment tables, and reusable regex transformation patterns.
• openobserve-api-management for alerts, dashboards, organizations, users, streams, actions, AI, node and platform administration, and other control-plane APIs.

Two further crates support them rather than owning a domain:

• openobserve-api-common for shared HTTP types, extractors, and authentication.
• openobserve-core for application services and business logic.

API crates must not depend on one another. Cross-domain behavior belongs in a non-API shared crate such as openobserve-core, common, audit, or openobserve-api-common. This crate is the only layer that aggregates API crates.

When adding an API, choose its crate by the resource it primarily owns:

1. Data entering OpenObserve goes to src/api/ingest.
2. Reading or querying stored observability data goes to src/api/search.
3. Data transformation and processing configuration goes to src/api/pipelines.
4. CRUD, administration, automation, alerts, dashboards, stream and node management, health, authentication, and configuration go to src/api/management.

Code used by two or more API crates goes to openobserve-api-common only when it is transport-specific. Shared business behavior belongs in openobserve-core; shared metadata and general utilities belong in common. Business endpoints must never be placed in a common crate.

This is an internal workspace crate and is not published independently. New business logic should normally be implemented in openobserve-core, leaving this crate responsible for HTTP transport composition.
