Do not request segments from all nodes at once ---------------------------------------------- Key: ISPN-2580 URL: https://issues.jboss.org/browse/ISPN-2580 Project: Infinispan Issue Type: Enhancement Components: State transfer Affects Versions: 5.2.0.Beta5 Reporter: Radim Vansa Assignee: Adrian Nistor Priority: Blocker Fix For: 5.2.0.CR1 When a new node joins large cluster filled with data, it gets the new CH and REBALANCE_START command, and requests data from all nodes at once (or almost all with even distribution of segments). It may be not able to handle this amount of transfers in parallel even at the JGroups level - this results in data sent to the node and discarded at the receiver, sent again and again. With a heavy congestion the node just buffers fragments of a message from one sender and never passes this up. The number of StateRequestCommands(START_STATE_TRANSFER) should be limited so that the node is not congested.
