Overview

The HTAPSys workshop aims to bring together researchers, practitioners as well as students in the area of hybrid analytical and transactional processing (HTAP) systems to exchange their ideas, share the latest results and identify future directions in this area. All aspects of HTAP systems are of interest, including but not limited to (1) data organization (relational and beyond), (2) data transformation and synchronization (e.g., ETL and conversions between row vs. columnar or hybrid data formats), (3) HTAP system architecture (e.g., single unified vs. distributed and replicated separate stores), (4) optimization and scheduling of hybrid analytical and transactional workloads, (5) interoperability between specialized systems and data formats, (6) query interfaces and usability of HTAP systems and (7) verification, evaluation and benchmarking of HTAP systems. We welcome both regular research papers and visionary position papers.

Call for Papers

Submission Instructions

We welcome submissions describing original, unpublished work that is not being considered for publication by other venues.

Manuscripts should follow the latest IEEE proceedings format and be submitted as PDF files at: https://cmt3.research.microsoft.com/HTAPSys2026. The paper length should not exceed six (6) pages inclusive of everything (e.g., references).

HTAPSys is a single-anonymous workshop. Authors are expected to include their names and affiliations on the first page of the manuscript.

Evaluation Criteria and Reviewing Process

Submissions will be done through Microsoft CMT in a single-blind manner. Authors are expected to indicate their names, contact information and affiliations in their submission. During submission of a research paper, the submission site will request information about Conflicts of Interest (COI) of the paper’s authors with program committee (PC) members. It is the full responsibility of all authors of a paper to identify all (and only) PC members with potential COIs as per the definition provided here.
Definition of Conflict of Interest (COI):
An author X of an HTAPSys 2026 research paper has a COI with a PC member if and only if one or more of the following conditions hold:

• X is a co-author of an HTAPSys 2026 submission together with Y.
• X is a co-author of Y in a publication in the past three years.
• X has been a co-author of Y for 4 (or more) publications in the last 10 years.
• X has been a co-worker of Y in the same company or university within the past three years.
• X has been a collaborator of Y within the past three years (e.g., held a joint grant).
• X is or was Y’s primary thesis advisor or vice versa, no matter how long ago.
• X is a relative or a close personal friend of Y (or vice versa).

Papers with incorrect or incomplete conflict of interest information as of the submission closing time are subject to immediate rejection.
