Load Pyogrio data to DuckDB

Build a Pyogrio to DuckDB pipeline with your coding agent. One prompt scaffolds it with the dltHub AI harness, plus the Pyogrio API base URL, auth, endpoints, and incremental loading.

SourcePyogrioPyogrio API DocumentationDestinationDuckDBIn-process analytical database. The default local destination for dlt pipelines.

Pyogrio is a library that provides fast, bulk-oriented read and write access to GDAL/OGR vector data sources such as Shapefiles, GeoPackage, and GeoJSON. Everything needed to build a working Pyogrio → DuckDB pipeline is on this page: the API's base URL, authentication, endpoints, pagination and incremental field — plus a prompt that hands the whole job to your coding agent.


Build your Pyogrio to DuckDB pipeline

Paste this prompt into Claude, Codex, or Cursor. The agent does the rest.

Prompt
Run uvx dlthub-init@latest to build a pipeline from Pyogrio to DuckDB and run it on dltHub

That scaffolds a dltHub workspace and installs the dltHub AI harness — the project rules, the secrets-management skill, and the dlt MCP server your agent needs to work safely. From there it reads the Pyogrio API, proposes the endpoints to load, then writes, runs and validates the pipeline while you review rather than type. Credentials are inspected through MCP tools, so your agent never reads secrets.toml itself. How the LLM-native workflow works →

Prefer to write it yourself? Every fact the agent uses is below.


Pyogrio API at a glance

Base URLN/A
Example endpointGET pyogrio.read_dataframe
AuthenticationNot applicable; Pyogrio is a local file I/O library — sent in the request header
PaginationNot paginated
Incremental fieldpath_or_buffer
API referencehttps://pyogrio.readthedocs.io/en/latest/api.html

These values come from the Pyogrio API reference — the authoritative source if anything here looks out of date.


How do I authenticate with the Pyogrio API?

Pyogrio is a Python library for bulk-oriented vector I/O using GDAL/OGR and does not provide a REST API or any authentication mechanisms.

No credentials required. The Pyogrio API is public, so there is nothing to obtain and nothing to add to .dlt/secrets.toml — the pipeline above runs as written.


What Pyogrio data can I load into DuckDB?

These are the Pyogrio endpoints dlt can load into DuckDB:

ResourceEndpointMethodData selectorDescription
list_driverspyogrio.list_driversGETdictList drivers available in GDAL.
list_layerspyogrio.list_layersGETlistList layers in an OGR data source.
read_infopyogrio.read_infoGETdictRead information about an OGR data source.
read_boundspyogrio.read_boundsGETtupleRead the total bounds of an OGR data source.
read_dataframepyogrio.read_dataframeGETGeoDataFrameRead from an OGR data source to a GeoPandas GeoDataFrame.

How do I load only new Pyogrio records?

Pyogrio exposes path_or_buffer on pyogrio.read_dataframe, so dlt can request only the records that changed since the last run. Set it as the cursor_path and dlt tracks the high-water mark for you between runs.

{"name": "read_dataframe", "endpoint": { "path": "pyogrio.read_dataframe", "incremental": {"cursor_path": "path_or_buffer", "initial_value": "2024-01-01T00:00:00Z"}, }}

On the first run dlt loads everything from initial_value; on every run after that it requests only what changed and appends with write_disposition="merge" if you set a primary key. See incremental loading.


What does the generated Pyogrio pipeline look like?

A standard dlt REST API pipeline — the same code you would write by hand, loading read_dataframe and read_info from the Pyogrio API into DuckDB:

import dlt from dlt.sources.rest_api import RESTAPIConfig, rest_api_resources @dlt.source def pyogrio_source(): config: RESTAPIConfig = { "client": { "base_url": "N/A", }, "resources": [ {"name": "read_dataframe", "endpoint": {"path": "pyogrio.read_dataframe"}}, {"name": "read_info", "endpoint": {"path": "pyogrio.read_info", "data_selector": "dict"}} ], } yield from rest_api_resources(config) def load_pyogrio_to_duckdb() -> None: pipeline = dlt.pipeline( pipeline_name="pyogrio_pipeline", destination="duckdb", dataset_name="pyogrio_data", ) load_info = pipeline.run(pyogrio_source()) print(load_info) if __name__ == "__main__": load_pyogrio_to_duckdb()

Run it with python pyogrio_pipeline.py. The agent iterates on this until it loads cleanly — you review and approve, rather than write it from scratch.


How do I query Pyogrio data in DuckDB?

dlt creates one table per resource. Query the loaded data with Python or SQL — or ask your agent to, through the MCP server's execute_sql_query tool.

Python (pandas DataFrame):

import dlt data = dlt.pipeline("pyogrio_pipeline").dataset() df = data.read_dataframe.df() print(df.head())

SQL:

SELECT * FROM pyogrio_data.read_dataframe LIMIT 10;

See querying your data with dataset and exploring it in marimo notebooks.


How do I deploy the Pyogrio to DuckDB pipeline in production?

The pipeline runs locally, which is ideal for prototyping and one-off analysis. When you need it on a schedule, monitored on every load, and shared with your team, deploy the same dlt code on the dltHub platform — no infrastructure to maintain. The prompt above already ends with "run it on dltHub", so your agent can take it there directly.

  • Deploy & schedule — run the pipeline as a managed job with automatic retries.
  • Monitor — observable job queues, alerting, and load metrics for every run.
  • Transform — promote raw Pyogrio loads into governed, documented models.
  • Visualize & share — explore data in notebooks and publish live dashboards instead of static screenshots.

What other destinations can I load Pyogrio data to?

dlt loads into any of these — only the destination argument changes:

DestinationExample value
PostgreSQL"postgres"
BigQuery"bigquery"
Snowflake"snowflake"
Redshift"redshift"
Databricks"databricks"
Filesystem (S3, GCS, Azure)"filesystem"

Set dlt.pipeline(destination="snowflake") and add credentials in .dlt/secrets.toml. On the dltHub platform the same pipeline runs against a managed Iceberg lakehouse. See the full destinations list.
