Examples of org.apache.phoenix.coprocessor.ServerCachingProtocol$ServerCacheFactory

org.apache.phoenix.coprocessor.ServerCachingProtocol
EndPoint coprocessor to send a cache to a region server. Used for: a) hash joins, to send the smaller side of the join to each region server b) secondary indexes, to send the necessary meta data to each region server @since 0.1
