zhijiang created FLINK-7377: ------------------------------- Summary: Implement FixedBufferPool for floating buffers in SingleInputGate Key: FLINK-7377 URL: https://issues.apache.org/jira/browse/FLINK-7377 Project: Flink Issue Type: Task Components: Core Affects Versions: 1.4.0 Reporter: zhijiang Assignee: zhijiang
Currently the number of network buffers in {{LocalBufferPool}} for {{SingleInputGate}} is limited by {{a * <number of channels> + b}}, where a is the number of exclusive buffers for each channel and b is the number of floating buffers shared by all channels. Considering the credit-based flow control feature, we want to implement a new fixed size buffer pool type used to manage the floating buffers for {{SingleInputGate}}. Compared with {{LocalBufferPool}}, this is a non-rebalancing buffer pool which will not participate in redistributing the left available buffers in {{NetworkBufferPool}}. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
