Simon Willnauer commented on LUCENE-8833: ----------------------------------------- I do like the idea of #warm but the footprint is much bigger since it's a public API. I mean for my specific usecase I'd subclass mmap anyway and it would make it easier that way. FileSwitchDirectory is quite heavy and isn't really build for what I wanna do. I basically would need a IndexInput factory that I can plug into a directory that can alternate between NIOFS and mmap etc. and conditionally preload the mmap. Either way I can work with both I just think this change is the minimum viable change. lemme know if you are ok moving forward. > Allow subclasses of MMapDirecory to preload individual IndexInputs > ------------------------------------------------------------------ > > Key: LUCENE-8833 > URL: https://issues.apache.org/jira/browse/LUCENE-8833 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Simon Willnauer > Priority: Major > Time Spent: 10m > Remaining Estimate: 0h > > I think it's useful for subclasses to select the preload flag on a per index > input basis rather than all or nothing.
