Disk-Based LSMs: An Unexpectedly Good Index for Partly Coherent CXL Memory

Abstract. We consider the design of an in-memory range index for systems with CXL shared memory in which only a small part of the memory is cache coherent. While existing index data structures can be ported to such a setting using a software-coherence approach, the result performs poorly. We find that the key reason is...
