Hi All,<div><br></div><div> SparseLargeTable appears not to be sparse at all. If you look at SparseLargeTable>>initChunkSize:size:arrayClass:base:defaultValue: you'll see tat each bin is initialized with an instance of the base class rather than being filled lazily. Further, instead of pvtNoCheckAt:put: lazily creating an entry in each bin as needed it simply throws away the write if the bin is empty. Instead the usage pattern is to create fully-populated instances and then make them sparse by sending zapDefaultOnlyEntries.</div>
<div><br></div><div>It seems to me that SparseLargeTable>>initChunkSize:size:arrayClass:base:defaultValue: should leave bins empty until pvtNoCheckAt:put: puts other than the default value. Since I want to create a sparse table with 2^32 entries the existing approach won't work.</div>
<div><br></div><div>I wondered whether anyone else had already fixed this or whether there's a good reason not to lazily initialize.</div><div><br></div><div>Best</div><div>Eliot</div>
