Class CacheConfig

java.lang.Object

com.exalead.mercury.mami.indexing.v10.CacheConfig

All Implemented Interfaces:

com.exalead.util.Checkable, java.io.Serializable

public class CacheConfig
extends java.lang.Object
implements com.exalead.util.Checkable, java.io.Serializable

PageCache configuration. Warning: The index page cache is limited to 32000 files in the index directory. If you get an error like "FileRAM: too many cached files (c_max_files=32767)", it means that the limit has been crossed and you should set a more aggressive compact policy.
