# Class CacheClientConfiguration

Ignite client cache configuration. Same thing as CacheConfiguration, but with a subset of properties that can be accessed from Ignite thin client (see IIgniteClient).

Note that caches created from server nodes can be accessed from thin client, and vice versa. The only difference is that thin client can not read or write certain CacheConfiguration properties, so a separate class exists to make it clear which properties can be used.

#### RebalanceDelay

Gets or sets delay upon a node joining or leaving topology (or crash) after which rebalancing should be started automatically.

##### Property Value

Type | Description
--- | ---
System.Int32 |

#### RebalanceThrottle

Time to wait between rebalance messages to avoid overloading of CPU or network. When rebalancing large data sets, the CPU or network can get over-consumed with rebalancing messages, which consecutively may slow down the application performance. This parameter helps tune the amount of time to wait between rebalance messages to make sure that rebalancing process does not have any negative performance impact. Note that application will continue to work properly while rebalancing is still in progress.
