-| `dapr_placement.keepAliveTime` | Sets the interval at which the placement service sends keepalive pings to daprd on the gRPC stream to check if the connection is still alive. Lower values will lead to shorter actor rebalancing time in case of pod loss, but higher network traffic during normal operation. Accepts values between `1s` and `10s`. <br> [Мore info](https://grpc.io/docs/guides/keepalive/) on gRPC keepalive | `2s` |

 | `dapr_placement.disseminateTimeout` | Sets the timeout period for dissemination to be delayed after actor membership change (usually related to pod restarts) so as to avoid excessive dissemination during multiple pod restarts. Higher values will reduce the frequency of dissemination, but delay the table dissemination. Accepts values between `1s` and `5s` | `2s` |
