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 rate_of_neonatal_hospital_stays_with_withdrawal table in this repository, by referencing it like:

"pa-gov/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync:latest"."rate_of_neonatal_hospital_stays_with_withdrawal"

or in a full query, like:

SELECT
    ":id", -- Socrata column ID
    "total_number_of_birth", -- Count of birth hospitalizations in specified timeframe.
    "age", -- Age of neonates (newborn child) (all less than 28 days of age in this dataset).
    ":@computed_region_nmsq_hqvv",
    ":@computed_region_d3gw_znnf",
    ":@computed_region_amqz_jbr4",
    ":@computed_region_r6rf_p9et",
    ":@computed_region_rayf_jjgk",
    "state_fips_code", -- These are the first 2 digits of the 5-digit Federal Information Processing Standard (FIPS) code that designate the State association. Each State has its own 2-digit number and each County within the state has its own 3-digit number which are combined into a 5-digit number to uniquely identify every US county. For more technical details : Federal Information Processing Standards Publications (FIPS PUBS) are issued by the National Institute of Standards and Technology (NIST) after approval by the Secretary of Commerce pursuant to Section 111 (d) of the Federal Property and Administrative Services Act of 1949 as amended by the Computer Security Act of 1987, Public Law 100-235. Federal Information Processing Standard (FIPS) 6-4, Counties and Equivalent Entities of the U.S., Its Possessions, and Associated Areas -- 90 Aug 31 , provides the names and codes that represent the counties and other entities treated as equivalent legal and/or statistical subdivisions of the 50 States, the District of Columbia, and the possessions and freely associated areas of the United States. Counties are considered to be the "first-order subdivisions" of each State and statistically equivalent entity, regardless of their local designations (county, parish, borough, etc.). Information gathered from census data - https://www.census.gov/library/reference/code-lists/ansi.html
    "latitude_longitude", -- Latitude and longitude coordinates in degrees for a centroid point for geographic area.
    "county_code_text", -- Pennsylvania county code provided as text (1-67 for counties sorted alphabetically, 0 for Commonwealth).
    "number_of_neonatal_hospital_2", -- Number of neonatal hospital stays with a diagnosis of withdrawal symptoms using ICD-10 code P96.1 in the first 28 days of life.
    "type_of_rate", -- Description of neonatal hospital stays with withdrawal symptoms.
    "gender", -- Gender of neonates or newborn child
    "total_number_of_birth_2", -- Describes number of birth hospitalizations.
    "number_of_neonatal_hospital_1", -- Indicates if the number of neonatal hospital stays with a diagnosis of withdrawal symptoms from maternal use of drugs of addiction in the first 28 days of life has been suppressed to protect confidentiality. Counts less than 11 are not provided.
    "year", -- Calendar year for measurement (January 1–December 31).
    "time_period", -- Period for measurement (annual, federal fiscal year, or quarterly, if available).
    "time_period_dates", -- Start and end dates of time period.
    "total_number_of_birth_1", -- Indicates if the number of birth hospitalizations has been suppressed to protect confidentiality. Counts less than 11 are not provided.
    "county_code_number", -- Pennsylvania county code provided as a number (1-67 for counties, 0 for Commonwealth).
    "geographic_area", -- Region for measure, either total for Commonwealth or individual county.
    "geographic_name", -- Name of geographic area.
    "geocoded_column", -- Georeferenced Latitude and Longitude column for use in visualization such as maps.
    "county_fips_code", -- Last 3 digits of the 5-digit Federal Information Processing Standard (FIPS) code that designate the county association. Each state has its own 2-digit number and each county within the state has its own 3-digit number which are combined into a 5-digit number to uniquely identify every US county.
    "number_of_neonatal_hospital", -- Number of neonatal hospital stays with a diagnosis of withdrawal symptoms from maternal use of drugs of addiction in the first 28 days of life. This count is provided by the Pennsylvania Health Care Cost Containment Council (PHC4).
    "rate_of_neonatal_hospital" -- Rate of neonatal hospital stays in which there is a diagnosis of withdrawal symptoms from maternal use of drugs of addiction in the first 28 days of life, relative to the total number of birth hospitalizations.
FROM
    "pa-gov/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync:latest"."rate_of_neonatal_hospital_stays_with_withdrawal"
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/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync 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/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync: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/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync" \
  --handler-options '{
    "domain": "data.pa.gov",
    "tables": {
        "rate_of_neonatal_hospital_stays_with_withdrawal": "39ba-sync"
    }
}'

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/rate-of-neonatal-hospital-stays-with-withdrawal-39ba-sync is just another Postgres schema.
