Summary: OOM on creating rebalance iterator while rebalancing cache with large values. Key: IGNITE-14003 URL: https://issues.apache.org/jira/browse/IGNITE-14003 Project: Ignite Issue Type: Bug Affects Versions: 2.9.1, 2.8.1, 2.9 Reporter: Ivan Daschinskiy Scenario 1. Start replicated cache on ignite node, memory region approx 6 Gb, heap 1Gb 2. Load significant amount of data to cache with values approx 200Kb (~20K kv pairs) 3. Start another node First node (supplier) will crash while initializing rebalance iterator with OOM Main reason -- all values, to whon pointed from leaf of BTree, are all loaded to buffer in BPlusTree#ForwardCursor. For replicated cache, 512 iterators for each partition are created at once. Reproducer is attached. -- This message was sent by Atlassian Jira (v8.3.4#803005)
