zhijiang updated FLINK-7378: ---------------------------- Summary: Create a fix size (non rebalancing) buffer pool type for the floating buffers (was: Implement the FixedBufferPool for floating buffers of SingleInputGate) > Create a fix size (non rebalancing) buffer pool type for the floating buffers > ----------------------------------------------------------------------------- > > Key: FLINK-7378 > URL: https://issues.apache.org/jira/browse/FLINK-7378 > Project: Flink > Issue Type: Sub-task > Components: Core > Reporter: zhijiang > Assignee: zhijiang > Fix For: 1.4.0 > > > 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)
