Overview

Background job for exporting interactions to CSV or NDJSON.

Streams filtered interactions to an export file stored in ActiveStorage. Supports filtering by provider, model, project, date range, tags, etc.

Supported Formats

  • CSV - Comma-separated values with headers
  • NDJSON - Newline-delimited JSON (one interaction per line)

Exported Fields

  • timestamp, project, provider, model, status
  • input_tokens, output_tokens, cost_total_cents
  • tags (pipe-separated)
  • request_payload, response_payload (JSON)
  • metadata

Examples:

Enqueue export job

blob = ExportJob.perform_now(
  format: :csv,
  filters: {
    provider: "openai",
    from: 30.days.ago,
    to: Date.current
  }
)
download_url = Rails.application.routes.url_helpers.rails_blob_url(blob)

Export specific project

ExportJob.perform_later(
  format: :ndjson,
  filters: { project: "support", review_state: "approved" }
)
