Furthermore, the Statistic Server (optionally AI-enhanced to provide cardinality and ndv) can be deployed separately, enabling GPU-heterogeneous computing and seamless hot-updates. - Extensible : VIDEX offers convenient interfaces allowing users to apply models like cardinality and ndv to downstream MySQL tasks (e.g., index recommendation); Latest News - [2025-05-28] 🥳🎉 VIDEX demo paper has been accepted by the VLDB 2025 Demo Track ! 🥳🎉 \"VIDEX: A Disaggregated and Extensible Virtual Index for the Cloud and AI Era\" (arXiv Preprint How to Cite) - [2025-04-28] VIDEX v0.1.0 is released. What's VIDEX The virtual index (aka hypothetical index ) aims to simulate the cost of indexes within SQL query plans, thereby demonstrating to users the impact of indexes on SQL plans without the need to create actual indexes on raw instances. This technology is widely applied in various SQL optimization tasks, including index recommendation and table join order optimization. As a reference, many other databases already have virtual index features from official or third-party sources, such as Postgres, ","default_branch":null,"files":null,"tree":[],"storefront":"/r/bytedance","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/bytedance/videx/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
