Query the Data Delivery Network

Query the DDN

The easiest way to query any data on Splitgraph is via the "Data Delivery Network" (DDN). The DDN is a single endpoint that speaks the PostgreSQL wire protocol. Any Splitgraph user can connect to it at data.splitgraph.com:5432 and query any version of over 40,000 datasets that are hosted or proxied by Splitgraph.

For example, you can query the tobacco_products_tax_licenses_current_monthly table in this repository, by referencing it like:

"pa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8:latest"."tobacco_products_tax_licenses_current_monthly"

or in a full query, like:

SELECT
    ":id", -- Socrata column ID
    ":@computed_region_d3gw_znnf",
    ":@computed_region_amqz_jbr4",
    "postal_code", -- Postal Code of the location where the license will be used as provided on the application
    "account", -- Account number used to track the tobacco products license provided by the Department of Revenue (DOR).  Account numbers are eight (8) digits in length.  Generally the first two digits of the license number are the county code.
    "location_1_state",
    "county", -- County of the location where the license/certificate will be used as provided on the application. PA has 67 counties. 
    "location_1_zip",
    "location_1_address",
    "legal_name", -- Legal Name of the entity or individual registering as provided on the application
    "expiration_date", -- Expiration date of the license or certificate.  Licenses must be renewed every year, expiring at the end of February.
    "country", -- Country of the location where the license will be used as provided on the application
    "location_1_city",
    "license_type", -- License type that was requested on the application. Other tobacco products includes the following: E-cigarettes, liquids or any other substance that goes into e-cigarettes, roll-your-own tobacco, pipe tobacco (periques, granulated, plug cut, crimp cut, ready rubbed, and other smoking tobacco), and  chewing tobacco (snuff, dry snuff, snuff flour, Cavendish, plug and twist tobacco, and fine cut).  Cigarette Stamping Agent license authorizes them to put stamps on packs of cigarettes for sale in PA. They are not authorized to sell to consumers unless they also have a retail license. Cig/OTP retail license authorizes them to sell cigarettes and/or other tobacco products to consumers Wholesale licenses authorize them to purchase stamped cigarettes and sell to retailers Vending authorizes the cigarettes to be sold at a vending machine.    Licenses can be combined, such as Wholesale/Vending which would authorize them to purchase stamped cigarettes from an CSA and sell them at a vending machine. More information available on Department of Revenue website: Cigarette licenses: https://www.revenue.pa.gov/TaxTypes/CigaretteTax/ForLicensees/Pages/default.aspx#    Other tobacco products (OTP): https://www.revenue.pa.gov/TaxTypes/OTPT/Pages/default.aspx  Prior detailed answers are available here:  https://revenue-pa.custhelp.com/app/answers/list/search/1/kw/tobacco%20license
    "location_1", -- Address of the location where the license will be used as provided on the application including the latitude and longitude as created during import of the data. 
    "trade_name", -- Trade Name of the location where the license will be used as provided on the application
    ":@computed_region_r6rf_p9et",
    ":@computed_region_rayf_jjgk",
    ":@computed_region_nmsq_hqvv"
FROM
    "pa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8:latest"."tobacco_products_tax_licenses_current_monthly"
LIMIT 100;

Connecting to the DDN is easy. All you need is an existing SQL client that can connect to Postgres. As long as you have a SQL client ready, you'll be able to query pa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8 with SQL in under 60 seconds.

This repository is an "external" repository. That means it's hosted elsewhere, in this case at data.pa.gov. When you querypa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8:latest on the DDN, we "mount" the repository using the socrata mount handler. The mount handler proxies your SQL query to the upstream data source, translating it from SQL to the relevant language (in this case SoQL).

We also cache query responses on the DDN, but we run the DDN on multiple nodes so a CACHE_HIT is only guaranteed for subsequent queries that land on the same node.

Query Your Local Engine

Install Splitgraph Locally
bash -c "$(curl -sL https://github.com/splitgraph/splitgraph/releases/latest/download/install.sh)"
 

Read the installation docs.

Splitgraph Cloud is built around Splitgraph Core (GitHub), which includes a local Splitgraph Engine packaged as a Docker image. Splitgraph Cloud is basically a scaled-up version of that local Engine. When you query the Data Delivery Network or the REST API, we mount the relevant datasets in an Engine on our servers and execute your query on it.

It's possible to run this engine locally. You'll need a Mac, Windows or Linux system to install sgr, and a Docker installation to run the engine. You don't need to know how to actually use Docker; sgrcan manage the image, container and volume for you.

There are a few ways to ingest data into the local engine.

For external repositories (like this repository), the Splitgraph Engine can "mount" upstream data sources by using sgr mount. This feature is built around Postgres Foreign Data Wrappers (FDW). You can write custom "mount handlers" for any upstream data source. For an example, we blogged about making a custom mount handler for HackerNews stories.

For hosted datasets, where the author has pushed Splitgraph Images to the repository, you can "clone" and/or "checkout" the data using sgr cloneand sgr checkout.

Mounting Data

This repository is an external repository. It's not hosted by Splitgraph. It is hosted by data.pa.gov, and Splitgraph indexes it. This means it is not an actual Splitgraph image, so you cannot use sgr clone to get the data. Instead, you can use the socrata adapter with the sgr mount command. Then, if you want, you can import the data and turn it into a Splitgraph image that others can clone.

First, install Splitgraph if you haven't already.

Mount the table with sgr mount

sgr mount socrata \
  "pa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8" \
  --handler-options '{
    "domain": "data.pa.gov",
    "tables": {
        "tobacco_products_tax_licenses_current_monthly": "ut72-sft8"
    }
}'

That's it! Now you can query the data in the mounted table like any other Postgres table.

Query the data with your existing tools

Once you've loaded the data into your local Splitgraph engine, you can query it with any of your existing tools. As far as they're concerned, pa-gov/tobacco-products-tax-licenses-current-monthly-ut72-sft8 is just another Postgres schema.
