In a worst case scenario it was up to 2% slower, however run-to-run variations of `pgbench` were >2%, which likely means that in a real system the performance impact of `pg_uuidv7` is negligible. ## Methods Performance benchmarks were evaluated using Postgres 18 and `pgbench`. The following functions were benchmarked: * the native `gen_random_uuid()` function which is built in since Postgres 13 * the `uuid_generate_v7()` function from this extension (`pg_uuidv7`) * a pure sql version of `uuid_generate_v7()` from [kjmph](https://gist.github.com/kjmph/5bd772b2c2df145aa645b837da7eca74) * the native `uuidv7()` function which is built in since Postgres 18 See the [benchmark directory](test/benchmark) for the implementation. ## Results ``` pgbench --client=8 --jobs=8 --transactions=200000 --file=${TEST}.sql -- SELECT gen_random_uuid();

Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License. 2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents. 2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.

These are regular Postgres UUIDs, so they can be used as primary keys, converted to and from strings, included in indexes, etc: ```sql SELECT uuid_generate_v7(); uuid_generate_v7 -------------------------------------- 018570bb-4a7d-7c7e-8df4-6d47afd8c8fc (1 row) ``` The timestamp component of these UUIDs can be extracted: ```sql SELECT uuid_v7_to_timestamptz('018570bb-4a7d-7c7e-8df4-6d47afd8c8fc'); uuid_v7_to_timestamptz ---------------------------- 2023-01-02 04:26:40.637+00 (1 row) ``` Timestamps can be converted to v7 UUIDs: ```sql SELECT uuid_timestamptz_to_v7('2023-01-02 04:26:40.637+00'); uuid_timestamptz_to_v7 -------------------------------------- 018570bb-4a7d-7630-a5c4-89b795024c5d (1 row) -- for date range queries set the second argument to true to zero the random bits SELECT uuid_timestamptz_to_v7('2023-01-02 04:26:40.637+00', true); uuid_timestamptz_to_v7 -------------------------------------- 018570bb-4a7d-7000-8000-000000000000 (1 row) ``` `uuid_generate_v7()` is as fast as the native `gen_random_uuid()` function. See the [benchmarks](BENCHMARKS.md) for more details. ## Background Version 7 UUIDs have a few advantages. They include a 48-bit Unix timestamp with millisecond accuracy and will overflow far in the future (10899 AD). They also include 74 random bits which means [billions can be created every second](https://en.wikipedia.org/wiki/Birthday_problem#Probability_table) without collisions. Because of their structure they are globally sortable and can be created in parallel in a distributed system. ## Quickstart > [!IMPORTANT] > These instructions are for x86_64 Linux. On other architectures (e.g. Apple M1, Raspberry Pi, etc.) follow the [build instructions](#build) instead. 1. Download the [latest `.tar.gz` release](https://github.com/fboulnois/pg_uuidv7/releases) and extract it to a temporary directory 2. Copy `pg_uuidv7.so` for your Postgres version into the Postgres module directory 3. Copy `pg_uuidv7--1.7.sql` and `pg_uuidv7.control` into the Postgres extension directory 4. Enable the extension in the database using `CREATE EXTENSION pg_uuidv7;` ```sh # example shell script to install pg_uuidv7 cd "$(mktemp -d)" curl -LO "https://github.com/fboulnois/pg_uuidv7/releases/download/v1.7.0/{pg_uuidv7.tar.gz,SHA256SUMS}" tar xf pg_uuidv7.tar.gz sha256sum -c SHA256SUMS PG_MAJOR=$(pg_config --version | sed 's/^.* \([0-9]\{1,\}\).*$/\1/') cp "$PG_MAJOR/pg_uuidv7.so" "$(pg_config --pkglibdir)" cp pg_uuidv7--1.7.sql pg_uuidv7.control "$(pg_config --sharedir)/extension" psql -c "CREATE EXTENSION pg_uuidv7;" ``` ## Build ### Build locally `pg_uuidv7` only requires the `libpq` headers and Postgres extension tools to build the code. On Debian, these headers are included in the `libpq-dev` and `postgresql-server-dev-all` packages. To build the code run `make`. To install the extension locally run `make install`. ### Build using Docker A [`Dockerfile`](Dockerfile) is available to build the code using the official Postgres Docker image: ```sh docker build . --tag pg_uuidv7 ``` A prebuilt x86_64 version of this image is on GitHub: ```sh docker pull ghcr.io/fboulnois/pg_uuidv7:1.7.0 ``` The prebuilt image [is similar](https://github.com/fboulnois/pg_uuidv7/pull/29#issuecomment-1996102946) to a vanilla Postgres instance so the extension needs to be enabled manually or with an initialization script with `CREATE EXTENSION pg_uuidv7;`. ## Test A separate [`Dockerfile`](test/Dockerfile) is available to build the extension against a specific version of Postgres and run the regression tests: ```sh docker build . --file test/Dockerfile --tag pgxn-test docker run --rm -it pgxn-test /bin/sh # once in container pg-start 18 pg-build-test # optionally run the benchmarks cd test/benchmark ./benchmark.sh postgres ``` ## Contributing See the [CONTRIBUTING.md](CONTRIBUTING.md) file for more details.
