Control whether the type metadata for PDX objects is persisted to disk. The default for this
setting is false. If you are using persistent regions with PDX then you must set this to true.
If you are using a WAN gateway with PDX then you should set this to true.

@param isPersistent true if the metadata should be persistent
@return this ClientCacheFactory
@since GemFire 6.6
@deprecated Pdx Persistence is not supported on client side. Even when set, it's internally
            ignored.
