name: Nuix API Rate Limits
description: Nuix does not publish explicit public rate limits for its REST APIs.
  The Core Engine REST API is deployed as a self-hosted service (on-premises or private
  cloud) and throttling behavior is governed by the server configuration, available
  worker counts, and license parameters rather than by a centrally enforced rate limit
  tier. Concurrency is bounded by the number of licensed workers acquired at client
  initialization.

limits:
  - name: Concurrent Workers
    description: Each REST API client session is initialized with a specified number
      of workers. The total workers available is bounded by the active Nuix license.
      Exceeding available workers results in a license acquisition failure.
    scope: Per Client Session
    unit: Workers
    enforced: true
    notes: Worker count is specified via the `workers` parameter when calling NewClient.
      Unused workers must be released by calling Close() on the client before program
      exit.
  - name: Concurrent Client Sessions
    description: The number of simultaneous client sessions is constrained by available
      license seats for the selected license type (enterprise-workstation, law-enforcement-desktop,
      web-reviewer, workflow).
    scope: Per License
    unit: Sessions
    enforced: true
    notes: Each license type has a finite seat count determined by the enterprise
      agreement. Sessions that are not properly closed may hold license seats until
      timeout.
  - name: Processing Jobs
    description: Asynchronous processing jobs (evidence ingestion, OCR, tagging,
      production exports) run as Functions on the server. Concurrent job limits depend
      on server hardware capacity and worker allocation, not a published API limit.
    scope: Per Server
    unit: Jobs
    enforced: false
    notes: Jobs can be paused, resumed, or cancelled via the REST API. Status is
      polled via the functions queue endpoint.
  - name: Search Pagination
    description: Search results from the Core Engine REST API are paginated. The
      caller specifies startIndex and numberOfRecordsRequested in each search request.
      No documented maximum page size is published.
    scope: Per Request
    unit: Records
    enforced: false
    notes: Large result sets should use pagination to avoid memory pressure on the
      server.
notes:
  - Nuix REST APIs are self-hosted; rate limits are not imposed by a SaaS gateway
    but by server capacity and license constraints.
  - For Nuix Discover SaaS deployments, service availability is tracked at status.nuix.com.
  - Contact Nuix support for guidance on tuning concurrency and worker allocation
    for high-volume deployments.
