Unlocking the Potential of CXL for Disaggregated Memory in Cloud-Native Databases

Summary: First CXL-switch disaggregated memory for cloud-native DBs (PolarCXLMem); reduces amplification, boosts bandwidth. PolarRecv enables rapid recovery; a multi-node coherence protocol supports cross-node sharing, with PolarDB showing up to 2x RDMA throughput. (summarized by gpt-5-nano on Feb 09 2026)
