It's simply the initial size given to a Map implementation so that its internal array bucket is already sized up. See HashMap constructor args for more info. Frankly, I think this is an example of option-itis - too many configuration options. ~ David Smiley

Is it correct that it controls how much heap is allocated to each cache at startup? I can see how it makes sense for queryResultCache since it is documented as an "ordered lists of document ids (DocList) based on a query, a sort, and the range of documents requested". Therefore the initial size can be computed. But the documentCache is a list of stored fields and fields vary in size so how is the initialSize determined? Cheers, Phil Farber
