I haven't worked with virtual threads for async IO myself, so this is more for my understanding... I read that virtual threads get pinned to the carrier platform thread when used for Foreign Function and Memory API. Since MMapDirectory on Java 21+ uses MemorySegment (part of FFM API), does this mean we cannot (should not) use virtual threads for MMAP file access use cases? Is the thinking here that we continue to use mmap access for the ANN graph search (fetching neighbor vector values for similarity checks), and independently leverage DirectIO with virtual threads for tasks like rescoring on vector similarity? -- This is an automated message from the Apache Git Service.
