We consume a lot of memory for the `indexIn` slices. If `indexIn` is of type `MemorySegmentIndexInput` the overhead of keeping loads of slices around just for cloning is far higher than the extra 12b per reader this adds (the slice description alone often costs a lot). In a number of Elasticsearch example uses with high segment counts I investigated, this change would save up to O(GB) of heap. -- This is an automated message from the Apache Git Service.
