1st Workshop on Hybrid Transactional/Analytical Processing Systems (HTAPSys 2026)
Co-located with ICDE 2026, Montreal, Canada.

Workshop website: https://sfu-dis.github.io/htapsys

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.

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We welcome submissions describing original, unpublished work that is not being considered for publication by other venues.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-blind workshop. Authors are expected to include their names and affiliations on the first page of the manuscript.
