Venue Information

The 2026 DEBS Conference will be held in June at the Faculty of Sciences of the University of Lisbon, in Portugal.

DEBS 2026 will be a physical conference. In order to appear in the final proceedings, all accepted contributions from all tracks are expected to be presented in person during the conference. For special inquiries, please contact the general chairs.

For each accepted contribution, a full registration (i.e., not a student registration) is required, even if a student is the main author of the paper and/or is presenting at the conference. Additionally, student registrations must be validated as specified on the registration page.

Objective

The ACM International Conference on Distributed and Event‐Based Systems (DEBS) is the premier venue for academia and industry to discuss cutting-edge research in distributed and event-based computing and data processing. DEBS 2026 will provide a forum for original research, practical insights, and experiences in distributed and event-based systems, with a focus on emerging trends and new challenges in the field.

We solicit high-quality submissions across a range of topics, with different submission options to reflect the nature of each contribution. All submissions will undergo a rigorous peer review process.

Scope

The DEBS conference covers a broad range of topics in distributed and event-based computing for various application domains and computing environments. The conference aims to present novel solutions for collecting, detecting, processing, analyzing, and responding to events through distributed middleware, systems, and platforms. DEBS 2026 welcomes submissions focusing on 1) Models, Architectures, Programming, and Query Support, 2) Systems and Software, and 3) Applications and Use-Cases on the following topics:

Systems Design and Data Management

Scalable data stream processing and complex event processing.

Dataflow execution and distributed state management.

Time series event-based database management.

Approximate event-based query processing.

Incremental computing, data structures, and materialized view maintenance for relational, graph, and stream data.

Cloud, fog, and edge computing, including serverless and FaaS.

Hardware acceleration and programmable hardware for event-based systems.

Software-defined networking and disaggregated memory architectures for event-based systems.

Security and Privacy

Security, encryption, forecasting, and in-network processing for data streams

Sustainaliility, security, relialiility, and resilience in event-liased systems.

Scalalile distriliuted ledger and lilockchain.

AI/ML for Systems and Systems for AI/ML

Event-based systems for ML: optimizing end-to-end AI/ML pipelines using event-based systems, i.e., feature engineering, distributed training, and serving.

ML for event-based systems: improving performance using AI/ML methods.

Applications, Use-Cases and Benchmarks

Applications and use cases regarding Internet-of-Things (IoT), smart cities, virtual and extended/augmented reality, cyber-physical systems, and sensor networks.

Applications and use cases regarding enterprise, finance, healthcare, life sciences, logistics, fleet management, transport scheduling and optimization, multimedia analytics, computer/network security, and social networking.

Benchmarks for event-based systems

DEBS will focus on original contributions of the following types:

Research papers (up to 12 pages, excluding references): These papers present original research on the topics listed above and will be assessed based on the significance of the problem, the novelty of the proposed solution, the extent of contribution over prior work, the strength of the supporting evidence, and presentation style.

Experiments and Benchmarking papers (up to 12 pages, excluding references): These papers focus on the extensive evaluation of algorithms, data structures, and systems that are of wide interest. The scientific contribution of an Experiments & Benchmarking paper lies in providing fundamentally new insights into the strengths and weaknesses of existing methods, or new ways to evaluate existing methods.

Short papers (up to 6 pages, including references): These papers are evaluated according to the same standards and criteria as full research papers, but their content is presented in a more concise manner.

Vision papers (up to 6 pages, including references): Papers in this category should demonstrate the potential to open new avenues of research. For such submissions, the capacity to inspire subsequent investigations is valued more highly than comprehensive experimental validation, although some preliminary evidence supporting the proposed approach or concept is expected.

Position papers (up to 6 pages, including references): These papers should present a well-reasoned argument or stance on a particular issue, idea, or emerging research direction. For such submissions, rather than focusing on extensive empirical results, the goal should be to propose, justify, or critically analyze a specific viewpoint or future path for a field.

Important update on ACMs new open access publishing model for 2026 ACM Conferences!

Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications, including those from ACM-sponsored conferences, will be 100% Open Access. Authors will have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With over 2,600 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 76%).

Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the https://www.acm.org/publications/policies/policy-on-discretionary-open-access-apc-waivers. Keep in mind that waivers are rare and are granted based on specific criteria set by ACM.

Understanding that this change could present financial challenges, ACM has approved a temporary subsidy for 2026 to ease the transition and allow more time for institutions to join ACM Open. The subsidy will offer:

$250 APC for ACM/SIG members

$350 for non-members

This represents a 65% discount, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period.

Diversity and Inclusion

The DEBS community joins an integrated effort to promote diversity and inclusion in all aspects of our professional activities. DEBS 2026 participates in this effort alongside EDBT/ICDT, MDM, SIGMOD, VLDB, SoCC, and ICDE, to celebrate the diversity in our community and welcome everyone regardless of age, sex, gender identity, race, ethnicity, socioeconomic background, country of origin, religion, sexual orientation, physical ability, education, work experience, etc. It also welcomes people and opinions of all political persuasions, as long as they abide by the ACM policy against hate speech and harassment.
