+| [options.scaleReads] | <code>string</code> | <code>&quot;\&quot;masters\&quot;&quot;</code> | Scale reads to the node with the specified role. Available values are "masters", "slaves" and "all". |
+| [options.maxRedirections] | <code>number</code> | <code>16</code> | When a MOVED or ASK error is received, client will redirect the command to another node. This option limits the max redirections allowed to send a command. |

+| [options.retryDelayOnFailover] | <code>number</code> | <code>2000</code> | When an error is received when sending a command(e.g. "Connection is closed." when the target Redis node is down), |
+| [options.retryDelayOnClusterDown] | <code>number</code> | <code>1000</code> | When a CLUSTERDOWN error is received, client will retry if `retryDelayOnClusterDown` is valid delay time. |
