| contents | Batch codes serve as critical tools for load balancing in distributed storage systems. While numerous constructions exist for specific batch sizes t, current methodologies predominantly rely on code dimension parameters, limiting their adaptability. Practical implementations, however, demand versatile batch code designs capable of accommodating arbitrary batch sizes-a challenge that remains understudied in the literature. This paper introduces a novel framework for constructing batch codes through finite groups and their subgroup structures, building on the quasi-uniform group code framework proposed by Chan et al. By leveraging algebraic properties of groups, the proposed method enables systematic code construction, streamlined decoding procedures, and efficient reconstruction of information symbols. Unlike traditional linear codes, quasi-uniform codes exhibit broader applicability due to their inherent structural flexibility.
Focusing on abelian 2-groups, the work investigates their subgroup lattices and demonstrates their utility in code design-a contribution of independent theoretical interest. The resulting batch codes achieve near-optimal code lengths and exhibit potential for dual application as locally repairable codes (LRCs), addressing redundancy and fault tolerance in distributed systems. This study not only advances batch code construction but also establishes group-theoretic techniques as a promising paradigm for future research in coded storage systems. By bridging algebraic structures with practical coding demands, the approach opens new directions for optimizing distributed storage architectures. |
