Heartbeat Manager Configuration

Key	Default	Type	Description

heartbeat.interval

| 10 s | Duration | Time interval between heartbeat RPC requests from the sender to the receiver side. | |

heartbeat.rpc-failure-threshold

| 2 | Integer | The number of consecutive failed heartbeat RPCs until a heartbeat target is marked as unreachable. Failed heartbeat RPCs can be used to detect dead targets faster because they no longer receive the RPCs. The detection time is heartbeat.interval * heartbeat.rpc-failure-threshold. In environments with a flaky network, setting this value too low can produce false positives. In this case, we recommend to increase this value, but not higher than heartbeat.timeout / heartbeat.interval. The mechanism can be disabled by setting this option to -1 | |

heartbeat.timeout

| 50 s | Duration | Timeout for requesting and receiving heartbeats for both sender and receiver sides. |
