LUCENE-10129: Add RamUsageEstimator.shallowSizeOf() for primitive arrays (#367)
Co-authored-by: Stefan Vodita <vodi...@amazon.com>
> Add RamUsageEstimator shallowSizeOf(long[]) overload that just calls
> sizeOf(long[])?

> Reporter: Robert Muir
> Priority: Major

> See LUCENE-10128 for an example. The problem is there is only a
> {{sizeOf(long[])}}, so if the programmer uses {{shallowSizeOf}} instead of
> {{sizeOf}} then it falls back to {{shallowSizeOf(Object)}} which does a bunch
> of reflection.
> This is pretty crazy because it can create performance traps. Should we just
> add a {{shallowSizeOf(long[])}} that calls {{sizeOf(long[])}}, so that things
> are fast? (same for other primitive arrays). It would solve the problem
> easily I think.
