Spatiotemporal Load Balancing for Near-Memory Accelerated Databases by Partial Resharding

This paper proposes an extension of query density-driven partitioning to support dynamically changing workloads and achieves significantly higher throughput than PIM-tree, a skew-resistant state-of-the-art data structure, during periods without workload changes.

Query Density-Driven Partitioning for Spatiotemporal Load Balancing on Processing-in-Memory Systems

A query density-driven key-range partitioning scheme that balances query density among PIM processors, allowing us to strike a balance between query load and data size via a parameter.
