CockroachDB supports efficiently storing and querying spatial data.
This page has instructions for migrating data from ESRI Shapefiles into CockroachDB using
We are using
shp2pgsql in the example below, but
ogr2ogr could also be used, e.g.
ogr2ogr -f PGDUMP file.sql -lco LAUNDER=NO -lco DROP_TABLE=OFF file.shp
ogr2ogr version of 3.1.0 or higher is required to generate data that can be imported into CockroachDB.
In the example below we will import a tornadoes data set that is available from the US National Weather Service (NWS).
Please refer to the documentation of your GIS software for instructions on exporting GIS data to Shapefiles.
Before You Begin
To follow along with the example below, you will need the following prerequisites:
Step 1. Download the Shapefile data
First, download and unzip the tornado data:
Step 2. Convert the Shapefile data to SQL
To load the tornado Shapefile into CockroachDB, we must first convert it to SQL using the
shp2pgsql 1950-2018-torn-initpoint.shp > tornado-points.sql &
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
tornadoes database to store the data in, and switch to it:
cockroach sql --insecure
CREATE DATABASE IF NOT EXISTS tornadoes; USE tornadoes;
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/tornado-points.sql') WITH ignore_unsupported_statements;
job_id | status | fraction_completed | rows | index_entries | bytes ---------------------+-----------+--------------------+-------+---------------+----------- 584874782851497985 | succeeded | 1 | 63645 | 0 | 18287213 (1 row)
