<title>LDBC Organizational Updates</title>
<link>https://ldbcouncil.org/post/ldbc-organizational-updates/</link>

<description><p>The Linked Data Benchmark Council (LDBC) was founded in 2012 with the goal of accelerating progress in graph data management.
Over the years, LDBC&rsquo;s membership grew to <a href="https://ldbcouncil.org/organizational-members/">20+ companies</a> and its operations extended to graph query languages and schemas.
This growth necessitated a rethink of the organization&rsquo;s governance and funding structure.</p>
<p>Last December, the LDBC met in London to decide on future leadership, governance, and finances. The outcome of this meeting is briefly summarized below.</p>
<h4 id="leadership">Leadership</h4>
<ul>
<li><a href="https://www.linkedin.com/in/henry-gabb-8b5b762/">Dr Henry Gabb</a> became LDBC&rsquo;s new chair. He was previously Intel’s representative in the LDBC and brings considerable expertise in benchmarking, hardware, and application development in the graph domain.</li>
<li><a href="https://www.linkedin.com/in/alastair-green-65a861a7/">Alastair Green</a> remains as LDBC vice chair.</li>
<li><a href="https://www.linkedin.com/in/basteer/">Dr Benjamin Steer</a> and <a href="https://www.linkedin.com/in/qishipeng/">Shipeng Qi</a> remain on the <a href="https://ldbcouncil.org/leadership/">Board of Directors</a>.</li>
<li><a href="https://szarnyasg.org/">Dr Gabor Szarnyas</a> returned to the Board. He is the maintainer of the LDBC Social Network Benchmark and the LDBC Graphalytics graph analytics benchmark.</li>
</ul>
<p>The LDBC thanked <a href="https://homepages.cwi.nl/~boncz/">Prof Peter Boncz</a> for his many contributions to the organization, including serving as chair or vice chair from inception until 2024.</p>
<h4 id="membership">Membership</h4>
<p>The annual LDBC membership fee for organizations is based on a <a href="https://ldbcouncil.org/becoming-a-member/#annual-membership-fees">tiered fee structure</a> related to company size. Note that the &ldquo;sponsor member&rdquo; tier is no longer available. Individual associate membership continues to be free.</p>
<p>To help build the graph community, the application process for individual LDBC membership was streamlined. You can expect faster turnaround times for applications.</p>
<h4 id="looking-ahead">Looking ahead</h4>
<p>Strategic planning is underway for 2025 and beyond. If you have any questions or feedback, please contact us at <a href="mailto:[email protected]">[email protected]</a>.</p>

<title>Record-Breaking SNB Interactive Results for GraphScope</title>
<link>https://ldbcouncil.org/post/record-breaking-snb-interactive-results-for-graphscope/</link>
<pubDate>Sun, 26 May 2024 00:00:00 +0000</pubDate>
<guid>https://ldbcouncil.org/post/record-breaking-snb-interactive-results-for-graphscope/</guid>
<description><p>We are happy to annonunce new <a href="https://ldbcouncil.org/benchmarks/snb-interactive/">audited results for the SNB Interactive workload</a>, achieved by the open-source <a href="https://github.com/alibaba/GraphScope">GraphScope Flex</a> system.</p>
<p>The current audit of the system has broken several records:</p>
<ul>
<li>It achieved 130.1k ops/s on scale factor 100, compared to the previous record of 48.8k ops/s.</li>
<li>It achieved 131.3k ops/s on scale factor 300, compared to the previous record of 48.3k ops/s.</li>
<li>It is the first system to successfully complete the benchmark on scale factor 1000. It achieved a throughput of 127.8k ops/s</li>
</ul>
<p>The audit was commissioned by the <a href="https://www.alibabacloud.com/">Alibaba Cloud</a> and was conducted by <a href="https://www.linkedin.com/in/arnau-prat-a70283bb/">Dr. Arnau Prat-Pérez</a>, one of the original authors of the SNB Interactive benchmark. The queries were implemented as C++ stored procedures and the benchmark was executed on the Alibaba Cloud&rsquo;s infrastructure. The <a href="https://ldbcouncil.org/benchmarks/snb/LDBC_SNB_I_20240514_SF100-300-1000_graphscope-executive_summary.pdf">executive summary</a>, <a href="https://ldbcouncil.org/benchmarks/snb/LDBC_SNB_I_20240514_SF100-300-1000_graphscope.pdf">full disclosure report</a>, and <a href="https://datasets.ldbcouncil.org/audits/LDBC_SNB_I_20240514_SF100-300-1000_graphscope-attachments.tar.gz">supplementary package</a> describe the benchmark&rsquo;s steps and include instructions for reproduction.</p>
<p>LDBC would like to congratulate the GraphScope Flex team on their record-breaking results.</p>

<title>Launching open-source language tools for ISO/IEC GQL</title>
<link>https://ldbcouncil.org/post/ldbc-announces-open-source-gql-tools/</link>
<pubDate>Thu, 09 May 2024 00:00:00 +0000</pubDate>
<guid>https://ldbcouncil.org/post/ldbc-announces-open-source-gql-tools/</guid>
<description><p>Following the publication of ISO/IEC GQL (graph query language) in April 2024, LDBC today launches open-source language engineering tools to help implementers, and assist in generation of code examples and tests for the GQL language. See this <a href="https://ldbcouncil.org/pages/opengql-announce">announcement from Alastair Green, Vice-chair of LDBC</a>.</p>
<p>These tools are the work of the <strong>LDBC GQL Implementation Working Group</strong>, headed up by Michael Burbidge. Damian Wileński and Dominik Tomaszuk have worked with Michael to create these artefacts based on his ANTLR grammar for GQL.</p>

<title>Announcing the Official Release of LDBC Financial Benchmark v0.1.0</title>
<link>https://ldbcouncil.org/post/announcing-the-official-release-of-ldbc-financial-benchmark/</link>
<pubDate>Tue, 27 Jun 2023 00:00:00 +0000</pubDate>
<guid>https://ldbcouncil.org/post/announcing-the-official-release-of-ldbc-financial-benchmark/</guid>
<description><p>We are delighted to announce the official release of the initial version (v0.1.0) of <a href="https://ldbcouncil.org/benchmarks/finbench/">Financial Benchmark (FinBench)</a>.</p>
<p>The Financial Benchmark (FinBench) project defines a graph database benchmark targeting financial scenarios such as anti-fraud and risk control. It is maintained by the <a href="https://ldbcouncil.org/benchmarks/finbench/ldbc-finbench-work-charter.pdf">LDBC FinBench Task Force</a>. The benchmark has one workload currently, <strong>Transaction Workload</strong>, capturing OLTP scenario with complex read queries that access the neighbourhood of a given node in the graph and write queries that continuously insert or delete data in the graph.</p>
<p>Compared to LDBC SNB, the FinBench differs in application scenarios, data patterns, and workloads, resulting in different schema characteristics, latency bounds, path filters, etc. For a brief overview, see the <a href="https://ldbcouncil.org/benchmarks/finbench/finbench-talk-16th-tuc.pdf">slides</a> in the 16th TUC. The <a href="https://arxiv.org/pdf/2306.15975.pdf">Financial Benchmark&rsquo;s specification</a> can be found on arXiv.</p>
<p>The release of FinBench initial version (v0.1.0) was approved by LDBC on June 23, 2023. It is the good beginning of FinBench. In the future, the FinBench Task Force will polish the benchmark continuously.</p>
<p>If you are interested in joining FinBench Task Force, please reach out at info at ldbcouncil.org or qishipeng.qsp at antgroup.com.</p>

<ol>
<li>
<p>Our paper <a href="https://ldbcouncil.org/docs/papers/ldbc-snb-bi-vldb-2022.pdf">The LDBC Social Network Benchmark: Business Intelligence Workload</a> was published in PVLDB.</p>
</li>
<li>
<p>David Püroja just completed his MSc thesis on creating a design towards <a href="https://ldbcouncil.org/docs/papers/msc-thesis-david-puroja-snb-interactive-v2-2023.pdf">SNB Interactive v2</a> at CWI&rsquo;s Database Architectures group. David and I gave a deep-dive talk at the FOSDEM conference&rsquo;s graph developer room titled <a href="https://fosdem.org/2023/schedule/event/graph_ldbc/">The LDBC Social Network Benchmark</a> (<a href="https://www.youtube.com/watch?v=YNF6z6gtXY4">YouTube mirror</a>).</p>
