Perform caching operations using Caffeine Cache with an attached CacheLoader.

Parameters

Take a look at the configuration options for the component. Parameters supported by Double Braces expressions are marked with (DB).

Required Tab

Parameter	Description	Default value	Data type
Cache Name (DB)	the cache name	N/A	string
Fail On Error	If true will stop pipeline with an error, if false will let the pipeline continue but the output will show a property success with value false	false	boolean

Optional Tab

Parameter	Description	Default value	Data type
Action	To configure the default cache action. If an action is set in the message header, then the operation from the header takes precedence.		string
Create Cache If Not Exist	Automatic create the Caffeine cache if none has been configured or exists in the registry.	true	boolean
Eviction Type	Set the eviction Type for this cache	SIZE_BASED	string
Expire After Access Time	Specifies that each entry should be automatically removed from the cache once a fixed duration has elapsed after the entry’s creation, the most recent replacement of its value, or its last read. Access time is reset by all cache read and write operations. The unit is in seconds.	300	number
Expire After Write Time	Specifies that each entry should be automatically removed from the cache once a fixed duration has elapsed after the entry’s creation, or the most recent replacement of its value. The unit is in seconds.	300	number
Initial Capacity	Sets the minimum total size for the internal data structures. Providing a large enough estimate at construction time avoids the need for expensive resizing operations later, but setting this value unnecessarily high wastes memory.	N/A	number
Key (DB)	To configure the default action key. If a key is set in the message header, then the key from the header takes precedence.	N/A	string
Maximum Size	Specifies the maximum number of entries the cache may contain. Note that the cache may evict an entry before this limit is exceeded or temporarily exceed the threshold while evicting. As the cache size grows close to the maximum, the cache evicts entries that are less likely to be used again. For example, the cache may evict an entry because it hasn’t been used recently or very often. When size is zero, elements will be evicted immediately after being loaded into the cache. This can be useful in testing, or to disable caching temporarily without a code change. As eviction is scheduled on the configured executor, tests may instead prefer to configure the cache to execute tasks directly on the same thread.	N/A	number
Stats Enabled	To enable stats on the cache	false	boolean
Value Type (DB)	The cache value type, default java.lang.Object	N/A	string

Headers Tab

Parameter	Description	Default value	Data type
CamelCaffeineAction (DB)	The action to execute. Possible values: CLEANUP PUT PUT_ALL GET GET_ALL INVALIDATE INVALIDATE_ALL AS_MAP	N/A	string
CamelCaffeineActionHasResult	The flag indicating whether the action has a result or not.	false	boolean
CamelCaffeineActionSucceeded	The flag indicating whether the action was successful or not.	false	boolean
CamelCaffeineKey (DB)	The key for all actions on a single entry.	N/A	string
CamelCaffeineKeys (DB)	The keys to get (GET_ALL), to invalidate (INVALIDATE_ALL) or existing (AS_MAP) according to the action.	N/A	JSON
CamelCaffeineValue (DB)	The value of key for all put actions (PUT or PUT_ALL).	N/A	string
CamelCaffeineOldValue (DB)	The old value returned according to the action.	N/A	string

Successful executions should output at least a property "success": true
