The same is probably true for LeafSetNodes and their NodeWithValue keys.</p> <p>While these duplicates are small in each instance (40-100 bytes each), there are 1.4M MapEntry nodes in the dump and strings are accounting for 18% of the allocated heap - thus we should attempt to de-duplicate them while restoring the data stream.</p> CONTROLLER-1908 Deduplicate NodeIdentifierWithPredicate/LeafNode values from incoming streams Improvement High Resolved Done Robert Varga Robert Varga Mon, 26 Aug 2019 19:40:48 +0000 Wed, 20 Nov 2019 14:37:55 +0000 Tue, 5 Nov 2019 07:48:20 +0000 Magnesium Sodium SR1 Neon SR3 clustering 0 2 <p>This reduces memory footprint from 895MiB to 853MiB (-42MiB, 4.7%) by eliminating ~646K retained objects.</p> Blocks CONTROLLER-1909 Development Rank 0|i03oq7:
