> Lucene currently uses ReadAdvice.RANDOM when opening these files. I think
it would be better to use RANDOM_PRELOAD.
As per the documentation for RANDOM_PRELOAD:
_This should only be used on very small files that can be expected to fit
in RAM with very high confidence._
Hence, I am wondering if it can have adverse impact for cases having small
page cache. While https://github.com/apache/lucene/pull/13264 adds way to
configure ReadAdvice, that applies to all file formats I guess. It would be
great, if users can tune the ReadAdvice for specific formats, depending on the
server page cache and data size.
