I am planning to use SortingMergePolicy where all the merge-participating segments are already sorted... I understand that I need to define a DocMap with old-new doc-id mappings.
Is it possible to optimize the eager loading of DocMap and make it kind of lazy load on-demand? Ex: Pass List<AtomicReader> to the caller and ask for next new-old doc mapping.. Since my segments are already sorted, I could save on memory a little-bit this way, instead of loading the full DocMap upfront -- Ravi
