Clay: Fine-Grained Adaptive Partitioning for General Database Schemas
Summary: Clay is an online partitioner for general schemas with FKs, not limited to tree structures. It uses fine-grained blocks of hot and co-accessed data to balance load and minimize movement, delivering up to 15x throughput and 99% latency reduction. (summarized by gpt-5-nano on Feb 09 2026)
