A DuckDB extension for graph workloads that supports the SQL/PGQ standard. For more information, please see the documentation page.
This repository is currently a research project and a work in progress. Feel free to play around with it and give us feedback.
Since DuckDB v1.0.0, DuckPGQ can be loaded as a community extension without requiring the unsigned
flag. From any DuckDB instance, the following two commands will allow you to install and load DuckPGQ:
install duckpgq from community;
load duckpgq;
See the DuckPGQ community extension page for more information.
For older DuckDB versions there are two ways to install the DuckPGQ extension.
Both ways require DuckDB to be launched in the unsigned
mode.
The first way is by setting the custom_extension_repository
command (see below). The other way is by directly downloading the extension file for your OS + architecture (see the DuckPGQ availibility section)
For CLI:
duckdb -unsigned
set custom_extension_repository = 'http://duckpgq.s3.eu-north-1.amazonaws.com';
force install 'duckpgq';
load 'duckpgq';
For Python:
import duckdb
conn = duckdb.connect(config = {"allow_unsigned_extensions": "true"})
conn.execute("set custom_extension_repository = 'http://duckpgq.s3.eu-north-1.amazonaws.com';")
conn.execute("force install 'duckpgq';")
conn.execute("load 'duckpgq';")
To use the extension, check the direct download links below. To install and load the extension, launch DuckDB in unsigned mode and execute the commands:
force install 'path/to/duckpgq_extension';
load 'duckpgq';

DuckDB extensions uses VCPKG for dependency management. Enabling VCPKG is very simple: follow the installation instructions or just run the following:
git clone https://github.com/Microsoft/vcpkg.git
./vcpkg/bootstrap-vcpkg.sh
export VCPKG_TOOLCHAIN_PATH=`pwd`/vcpkg/scripts/buildsystems/vcpkg.cmake
Note: VCPKG is only required for extensions that want to rely on it for dependency management. If you want to develop an extension without dependencies, or want to do your own dependency management, just skip this step. Note that the example extension uses VCPKG to build with a dependency for instructive purposes, so when skipping this step the build may not work without removing the dependency.
Checkout git submodules:
git submodule update --init --recursive
Now to build the extension, run:
make <debug> GEN=ninja
The location of the binaries depends on the BUILD_TYPE
flag (release
or debug
) specified during the build process. By default, the binaries are organized as follows:
- DuckDB binary:
./build/release/duckdb
- Unit tests:
./build/release/test/unittest
- DuckPGQ extension:
./build/release/extension/duckpgq/duckpgq.duckdb_extension
- DuckDB binary:
./build/debug/duckdb
- Unit tests:
./build/debug/test/unittest
- DuckPGQ extension:
./build/debug/extension/duckpgq/duckpgq.duckdb_extension
Ensure you specify the appropriate BUILD_TYPE
flag when configuring the build to place binaries in the corresponding directory.
duckdb
is the binary for the duckdb shell with the extension code automatically loaded.unittest
is the test runner of duckdb. Again, the extension is already linked into the binary.duckpgq.duckdb_extension
is the loadable binary as it would be distributed.
To run the extension code, simply start the shell with ./build/release/duckdb
.
Caution
Any query containing SQL/PGQ syntax requires a -
at the start of the query when building the extension from the source, otherwise, you will experience a segmentation fault. This is not the case when loading the extension from DuckDB.
Different tests can be created for DuckDB extensions. The primary way of testing DuckDB extensions should be the SQL tests in ./test/sql
. These SQL tests can be run using:
make test
To install your extension binaries from S3, you will need to do two things. Firstly, DuckDB should be launched with the
allow_unsigned_extensions
option set to true. How to set this will depend on the client you're using. Some examples:
CLI:
duckdb -unsigned
Python:
con = duckdb.connect(':memory:', config={'allow_unsigned_extensions' : 'true'})
NodeJS:
db = new duckdb.Database(':memory:', {"allow_unsigned_extensions": "true"});
Secondly, you will need to set the repository endpoint in DuckDB to the HTTP url of your bucket + version of the extension you want to install. To do this run the following SQL query in DuckDB:
SET custom_extension_repository='bucket.s3.eu-west-1.amazonaws.com/<your_extension_name>/latest';
Note that the /latest
path will allow you to install the latest extension version available for your current version of
DuckDB. To specify a specific version, you can pass the version instead.
After running these steps, you can install and load your extension using the regular INSTALL/LOAD commands in DuckDB:
INSTALL duckpgq
LOAD duckpgq
