CockroachDB supports efficiently storing and querying spatial data.
This page has instructions for migrating data from the GeoJSON format into CockroachDB using ogr2ogr
and IMPORT
.
In the example below we will import a data set with the locations of underground storage tanks in the state of Vermont (USA).
Before You Begin
To follow along with the example below, you will need the following prerequisites:
An ogr2ogr
version of 3.1.0 or higher is required to generate data that can be imported into CockroachDB.
Step 1. Download the GeoJSON data
First, download the storage tank GeoJSON data:
wget -O tanks.geojson https://geodata.vermont.gov/datasets/986155613c5743239e7b1980b45bbf36_162.geojson
Step 2. Convert the GeoJSON data to SQL
Next, convert the GeoJSON data to SQL using the following ogr2ogr
command:
ogr2ogr -f PGDUMP tanks.sql -lco LAUNDER=NO -lco DROP_TABLE=OFF tanks.geojson
An ogr2ogr
version of 3.1.0 or higher is required to generate data that can be imported into CockroachDB.
Step 3. Host the files where the cluster can access them
Each node in the CockroachDB cluster needs to have access to the files being imported. There are several ways for the cluster to access the data; for a complete list of the types of storage IMPORT
can pull from, see import file locations.
For local testing, you can start a local file server. The following command will start a local file server listening on port 3000:
python3 -m http.server 3000
Step 4. Prepare the database
Next, create a database to hold the storage tank data:
cockroach sql --insecure
CREATE DATABASE IF NOT EXISTS tanks;
USE tanks;
Step 5. Import the SQL
Since the file is being served from a local server and is formatted as PostgreSQL-compatible SQL, we can import the data using the following IMPORT PGDUMP
statement:
IMPORT PGDUMP ('http://localhost:3000/tanks.sql');
job_id | status | fraction_completed | rows | index_entries | bytes
---------------------+-----------+--------------------+------+---------------+---------
588555793549328385 | succeeded | 1 | 2709 | 2709 | 822504
