Exclusive buffers can be used by only one particular channel. A channel can request additional floating buffers from a buffer pool shared across all channels belonging to the given input gate. The remaining floating buffers are optional and are acquired only if there are enough resources available. +The number of buffers in one pool calculated according to the above formula can be divided into two parts. The part below this configured value `taskmanager.network.memory.read-buffer.required-per-gate.max` is required. The excess part buffers, if any, is optional. A task will fail if the required buffers cannot be obtained in runtime. A task will not fail due to not obtaining optional buffers, but may suffer a performance reduction. If not explicitly configured, the default value is Integer.MAX_VALUE for streaming workloads, and 1000 for batch workloads.
