> @uschindler, I understand the complexity of completely rewriting all Lucene internals. However, IMO it is necessary to do so in parallel. Relying entirely on MMAP is a bad idea it is good for warmup queries. > > Ref: https://db.cs.cmu.edu/mmap-cidr2022/ Lucene has different access patterns that are not database like. MMAP works perfectly here. Lucene is using WORM when writing files. This paper is known to use and our long-time testing figured out that it does not apply to most Lucene workloads. -- This is an automated message from the Apache Git Service.
