`flink-gs-fs-hadoop` can also be configured by setting the following options in [Flink configuration file]({{< ref "docs/deployment/config#flink-配置文件" >}}):

| gs.filesink.entropy.enabled | Set this property to improve performance due to hotspotting issues on GCS. This option defines whether to enable entropy injection in filesink gcs path. If this is enabled, entropy in the form of temporary object id will be injected in beginning of the gcs path of the temporary objects. The final object path remains unchanged. |
| gs.http.connect-timeout | Set this property to [set the connection timeout](https://cloud.google.com/java/docs/reference/google-cloud-core/latest/com.google.cloud.http.HttpTransportOptions.Builder#com_google_cloud_http_HttpTransportOptions_Builder_setConnectTimeout_int_) for java-storage client. |

Subsequent calls will use this value adjusted according to the gs.retry.rpc-timeout-multiplier. |
| gs.retry.rpc-timeout-multiplier | Set this property to [controls the change in RPC timeout](https://cloud.google.com/java/docs/reference/gax/latest/com.google.api.gax.retrying.RetrySettings#com_google_api_gax_retrying_RetrySettings_getRpcTimeoutMultiplier__). The timeout of the previous call is multiplied by the RpcTimeoutMultiplier to calculate the timeout for the next call. |
