          public boolean isEagerTtl()

      Gets flag indicating whether expired cache entries will be eagerly removed from cache. If there is at least one cache configured with this flag set to `true`, Ignite will create a single thread to clean up expired entries in background.

    - #### getDefaultLockTimeout

          public long getDefaultLockTimeout()

      Returns:
        Default lock acquisition timeout. `0` and means that lock acquisition will never timeout.

          public ClientCacheConfiguration setPartitionLossPolicy(PartitionLossPolicy newVal)

      Parameters:

        Flag indicating whether data can be read from backup. If `false` always get data from primary node (never from backup).

    - #### setReadFromBackup

          public ClientCacheConfiguration setReadFromBackup(boolean readFromBackup)

      Parameters:
        `readFromBackup` - Read from backup.
      Returns:
        `this` for chaining.

    - #### getRebalanceBatchSize

          public int getRebalanceBatchSize()

      Returns:
        Size (in number bytes) to be loaded within a single rebalance message. Rebalancing algorithm will split total data set on every node into multiple batches prior to sending data.

    - #### setRebalanceBatchSize

          public ClientCacheConfiguration setRebalanceBatchSize(int rebalanceBatchSize)

      Parameters:
        `rebalanceBatchSize` - Rebalance batch size.
      Returns:
        `this` for chaining.

    - #### getRebalanceBatchesPrefetchCount

          public long getRebalanceBatchesPrefetchCount()

      To gain better rebalancing performance supplier node can provide more than one batch at rebalancing start and provide one new to each next demand request.
      Returns:
        Number of batches generated by supply node at rebalancing start. Minimum is 1.

    - #### setRebalanceBatchesPrefetchCount

          public ClientCacheConfiguration setRebalanceBatchesPrefetchCount(long rebalanceBatchesPrefetchCnt)

      Parameters:
        `rebalanceBatchesPrefetchCnt` - Rebalance batches prefetch count.
      Returns:
        `this` for chaining.

    - #### getRebalanceDelay

          public long getRebalanceDelay()

      Returns:
        Delay in milliseconds upon a node joining or leaving topology (or crash) after which rebalancing should be started automatically. Rebalancing should be delayed if you plan to restart nodes after they leave topology, or if you plan to start multiple nodes at once or one after another and don't want to repartition and rebalance until all nodes are started.

        Default value is `0` which means that repartitioning and rebalancing will start immediately upon node leaving topology. If `-1` is returned, then rebalancing will only be started manually.

    - #### setRebalanceDelay

          public ClientCacheConfiguration setRebalanceDelay(long rebalanceDelay)

      Parameters:
        `rebalanceDelay` - Rebalance delay.
      Returns:
        `this` for chaining.

    - #### getRebalanceMode

          public CacheRebalanceMode getRebalanceMode()

      Gets rebalance mode.
      Returns:
        `this` for chaining.

    - #### setRebalanceMode

          public ClientCacheConfiguration setRebalanceMode(CacheRebalanceMode rebalanceMode)

      Parameters:
        `rebalanceMode` - Rebalance mode.
      Returns:
        `this` for chaining.

    - #### getRebalanceOrder

          public int getRebalanceOrder()

      Returns:
        Cache rebalance order. Rebalance order can be set to non-zero value for caches with `SYNC` or `ASYNC` rebalance modes only.

        If cache rebalance order is positive, rebalancing for this cache will be started only when rebalancing for all caches with smaller rebalance order will be completed.

        Note that cache with order `0` does not participate in ordering. This means that cache with rebalance order `0` will never wait for any other caches. All caches with order `0` will be rebalanced right away concurrently with each other and ordered rebalance processes.

        If not set, cache order is 0, i.e. rebalancing is not ordered.

    - #### setRebalanceOrder

          public ClientCacheConfiguration setRebalanceOrder(int rebalanceOrder)

      Parameters:
        `rebalanceOrder` - Rebalance order.
      Returns:
        `this` for chaining.

    - #### getRebalanceThrottle

          public long getRebalanceThrottle()

      Returns:
        Time in milliseconds 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.

        Default value of `0` means that throttling is disabled.

    - #### setRebalanceThrottle

          public ClientCacheConfiguration setRebalanceThrottle(long newVal)

      Parameters:
        `newVal` - Rebalance throttle.
