-------------------------------
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}}.
