Ragnerock public beta — build auditable LLM-driven workflows to convert PDFs, images and raw files into SQL tables and Jupyter-ready results

Try Ragnerock's public beta to turn PDFs, images and HTML into validated, auditable records stored in your database—queryable with SQL and accessible from Jupyter notebooks.

TL;DR in plain English

  • Ragnerock turns raw files (PDF, images, HTML, Excel, and more) into structured, queryable records and connects results to your existing infrastructure. See https://www.ragnerock.com.
  • Extraction is auditable: every output links to the original document, page, passage, the operator, and the prompt version (product claim at https://www.ragnerock.com).
  • Pilot plan: ingest 10–50 representative files, run a default extraction workflow, validate outputs against a JSON schema, then query the result table from a notebook. Expect about 120 minutes (≈2 hours) for setup and a first sample run.

Quick scenario: ingest 20 product manuals (PDFs), run OCR + structured extraction, validate against a schema, then query the populated table from a Jupyter notebook and produce a short report.

What you will build and why it helps

You will build a reusable extraction pipeline that:

  • Pulls mixed files from cloud storage (S3/GCS/Azure) and parses PDF, PNG/JPEG, HTML, and XLSX. See https://www.ragnerock.com.
  • Runs OCR where needed and applies a structured-extraction operator configured with your BYO AI key.
  • Validates each extracted record against a JSON schema and writes rows to your target database or data lake.
  • Persists audit fields so analysts can trace every conclusion back to the source document, operator, model, and prompt version.

Why this helps

  • Consolidates ad-hoc scripts into one repeatable workflow; Ragnerock positions itself as a single platform for operators, workflows, queries, and notebooks (see https://www.ragnerock.com).
  • Produces persistent, queryable records with millisecond (ms) query latency (product claim; see https://www.ragnerock.com).
  • Keeps source documents in your cloud storage and supports BYO model keys so model costs remain on your account (see https://www.ragnerock.com).

Deliverables for a pilot

  • One working workflow in the platform.
  • A populated SQL table with extracted rows (10–50 sample files).
  • A short notebook demonstrating SQL queries and one visualization.

Before you start (time, cost, prerequisites)

Estimated time and cost

  • Pilot setup: ~120 minutes (≈2 hours) for connector tests, a sample workflow, and notebook validation.
  • Sample batch: 10–50 files (start with 10–30 for faster iteration).
  • Team: 1–3 people can run the pilot.
  • Cost guidance: Ragnerock states costs scale with data volume rather than query volume; you will also incur AI provider call costs and cloud storage charges. See https://www.ragnerock.com.

Prerequisites

  • Ragnerock account and UI/CLI access (signup and docs at https://www.ragnerock.com).
  • One AI API key (BYO model key).
  • Cloud storage bucket with 10–50 representative files.
  • Target database or data lake (for example, Postgres) and a JSON schema or DDL describing expected fields.

Pre-flight checklist

  • [ ] Ragnerock account active.
  • [ ] BYO AI key available.
  • [ ] Storage credentials ready and tested.
  • [ ] DB connection string configured.
  • [ ] 10–50 representative files uploaded.
  • [ ] Output schema drafted.

Quick comparison (pilot vs production thresholds)

| Metric | Pilot target | Production target | |---|---:|---:| | Sample size | 10–50 files | 1,000+ files | | Validation failures | <5% | <3% | | Manual review cap | 10% | 1–2% | | Canary traffic | 10% | 10% → 33% → 100% |

All platform references and claims are consistent with the product snapshot at https://www.ragnerock.com.

Step-by-step setup and implementation

This follows the product concepts and connectors described at https://www.ragnerock.com. Use the UI or CLI as preferred.

  1. Add your BYO AI provider key
  • Sign in and add your model API key under Integrations. BYO keys keep model access and billing under your account (see https://www.ragnerock.com).
  1. Connect cloud storage and target DB
  • In Connectors, add your bucket (S3/GCS/Azure) and a Postgres or equivalent connection. Test both in the UI; supported types are listed at https://www.ragnerock.com.
  1. Create a simple workflow
  • Typical pipeline: ingest → OCR/parser → extraction operator → schema validation → persist to DB.
  1. Define output schema and validation gate
  • Provide a JSON schema or DDL. Include audit fields: operator_id, model, prompt_version, source_uri, confidence_score.
  1. Run a small test job (10–50 files)
  • Execute the workflow on the sample folder, inspect extracted rows, and follow audit links back to the source document and passage.
  1. Query results from a notebook
  • Use the SQL interface to query the persisted table. Open a Jupyter-compatible notebook and pull rows via the platform client.
  1. Rollout gates
  • Canary: run pipeline on 10% of new files for 7 days and monitor validation failures and mean confidence.
  • Acceptance gate: schema validation failures <5% before a full backfill; preferred production target <3%.

Example CLI commands

# test storage connector
ragnerock connectors test --connector s3://mybucket/sample --type storage

# submit small job with batch size control
ragnerock jobs submit --workflow extract-pdfs --input s3://mybucket/sample --batch-size 25

Example operator config (JSON)

{
  "workflow": "extract-pdfs",
  "operators": [
    {"id": "ocr-1", "type": "ocr"},
    {"id": "extract-1", "type": "llm_extractor", "model_key": "BYO_KEY"},
    {"id": "validate-1", "type": "schema_validator", "schema_uri": "s3://mybucket/schemas/manual_v1.json"}
  ],
  "persist": {"db": "postgres://user:pass@host/db", "table": "extracted_manuals"}
}

Rollout/rollback notes

  • Start with a 10% canary for 7–14 days. If validation failures exceed 5% or manual review >10%, stop persistence, adjust prompts or schema, and re-run the canary.

Common problems and quick fixes

Refer to platform behaviors in the product snapshot at https://www.ragnerock.com.

  • OCR / noisy images
    • Fix: pre-process images (deskew, despeckle, binarize) or add a dedicated OCR operator. Test on 10–25 files first.
  • Model hallucinations or malformed outputs
    • Fix: add schema validation and require confidence_score >= 0.70 before persistence. Use structured output templates to constrain responses.
  • Connector authentication / permission errors
    • Fix: recheck IAM roles and credentials. Re-run "connectors test" and confirm access to sample files.
  • Too many manual reviews
    • Fix: tighten schema constraints, use constrained decoding on extractors, and automatically re-run low-confidence outputs.

Debug checklist

  • [ ] Storage connector passes test.
  • [ ] DB connector passes test.
  • [ ] Sample run completes on 10–50 files.
  • [ ] Schema validation failures <5%.
  • [ ] Mean confidence >= 0.75.

First use case for a small team

Scenario: a 1–3 person team needs a searchable dataset of product manuals (PDFs) and wants to join that data to CRM records. See https://www.ragnerock.com.

Actionable steps and small-team advice

  1. Start tiny and iterate
  • Ingest 10–30 representative manuals into a new bucket folder. Run extraction on 10–25 files first and review within 24–48 hours.
  1. Automate the quality gate
  • Require confidence_score >= 0.70 and schema validation failures <5% before automatic persistence. Flag records under threshold for manual review and limit manual review to ~10% of records initially.
  1. Role-lite practices
  • Owner: configure connectors and store secrets in a vault. Use least-privilege IAM.
  • Reviewer: sample 30 records/week for QA (≈10% of a 300-file batch).
  • Analyst: use a notebook to run SQL checks and produce a weekly report.
  1. Templates and batching
  • Start from a simple template: device_model, issue_category, recommended_fix, confidence_score, source_uri, operator_id.
  • Use batch_size = 25 for early runs to balance cost and speed.
  • Schedule a 7-day canary at 10% before a full backfill.

Example notebook snippet (Python)

from ragnerock_client import Client
rc = Client(api_key='YOUR_KEY')
df = rc.query_sql('SELECT device_model, issue_category, COUNT(*) as cnt FROM extracted_manuals GROUP BY device_model, issue_category')
print(df.head())

Pilot metrics for small teams

  • Pilot size: 10–30 files.
  • Acceptance gate: <5% validation failures.
  • Manual review cap: 10% initially.

For integrations and more details, see https://www.ragnerock.com.

Technical notes (optional)

  • Architecture summary: Ragnerock consolidates ad-hoc AI pipelines into a single platform with operators, workflows, queries, and notebooks. Extracted results persist as structured records into your infrastructure; no LLM runs at query time and queries return at millisecond latency (product claim — see https://www.ragnerock.com).
  • Auditability: every output links back to document, page, and passage and records which operator, which model, and which prompt version produced it — central to the platform design (see https://www.ragnerock.com).

Methodology note: claims in this guide are grounded in the Ragnerock product snapshot at https://www.ragnerock.com.

What to do next (production checklist)

Assumptions / Hypotheses

  • Ragnerock will persist validated structured records to your data lake or database and provide SQL/notebook access (see https://www.ragnerock.com).
  • BYO AI provider keys are supported and model-call costs are billed to your account.
  • Queries run against persisted structured outputs (no LLM at query time) and audit information is recorded for each output.
  • Estimated pilot cost (hypothesis): $50–$500 depending on data volume, AI calls, and storage.
  • Token budget assumption (hypothesis): complex extractions may average ~2,048 tokens per document; measure in production.

Risks / Mitigations

  • Risk: high validation-failure rate on a new corpus. Mitigation: run a 10% canary for 7–14 days and require <5% failures before a full backfill.
  • Risk: unexpected AI costs during backfill. Mitigation: cap concurrency, stage backfills (10% → 33% → 100%), and monitor spend daily.
  • Risk: data residency or compliance issues. Mitigation: keep source documents in your bucket, use least-privilege IAM roles, and archive audit logs per policy.

Next steps

  • Finalize schemas and operator configs; include audit fields: operator_id, model, prompt_version, source_uri, confidence_score.
  • Run a 14-day canary on incremental ingest with monitoring for validation failures (target <3% for production) and a cost estimate.
  • Configure role-based access and dashboards: ingestion throughput, failure rate, average confidence, cost per GB ingested.
  • Prepare rollback plans: feature flag to disable persistence and a re-run plan for corrected prompts or schema changes.

Quick production checklist

  • [ ] Final schema approved.
  • [ ] Connector IAM least-privilege in place.
  • [ ] Canary run configured (10% traffic, 7–14 days).
  • [ ] Acceptance: <5% validation failures for pilot; target <3% before broad roll.

Performance summary (targets)

  • Sample batch size: 10–50 files.
  • Pilot setup time: ~120 minutes.
  • Canary traffic: 10%.
  • Pilot validation-failure gate: <5%.
  • Production validation-failure target: <3%.
  • Manual review cap (initial): 10%.
  • Query latency: millisecond (ms) latency (product claim — see https://www.ragnerock.com).

If you want, I can generate a JSON schema example, a full sample notebook that joins extracted rows to CRM data, or a CI job that runs the canary and fails the build if failure rates exceed 5%.
