This is neat -- if Lucene implements enough top-down prefetch hinting, it might eventually be that DirectIO, alone, is sufficient for good query latency/throughput? I.e. we could stop entirely relying on OS to do its prefetching/caching (buffer cache), maybe, in very cold indices? Isn't `DirectIODirectory` today only inserting itself for merge context reading & writing? -- This is an automated message from the Apache Git Service.
