slot.idle.timeout
50000 Long The timeout in milliseconds for a idle slot in Slot Pool.

slotmanager.number-of-slots.max
2147483647 Integer Defines the maximum number of slots that the Flink cluster allocates. This configuration option is meant for limiting the resource consumption for batch workloads. It is not recommended to configure this option for streaming workloads, which may fail if there are not enough slots. Note that this configuration option does not take effect for standalone clusters, where how many slots are allocated is not controlled by Flink.
