Detailed Description

Creates instances of RegionAttributes.

An RegionAttributesFactory instance maintains state for creating RegionAttributes instances. The setter methods are used to change the settings that will be used for creating the next attributes instance with the {} method. If you create a factory with the default constructor, then the factory is set up to create attributes with all default settings. You can also create a factory by providing a RegionAttributes, which will set up the new factory with the settings provided in that attributes instance. Once a RegionAttributes is created, it can only be modified after it has been used to create a Region, and then only by using an AttributesMutator obtained from the region.

Attributes

Callbacks

CacheLoader [default: nullptr]

User-implemented plug-in for loading data on cache misses.
setCacheLoader RegionAttributes#getCacheLoader AttributesMutator#setCacheLoader

CacheWriter [default: nullptr]

User-implemented plug-in for intercepting cache modifications, e.g. for writing to an external data source.
setCacheWriter RegionAttributes#getCacheWriter AttributesMutator#setCacheWriter

CacheListener [default: nullptr]

User-implemented plug-in for receiving and handling cache related events.
setCacheListener RegionAttributes#getCacheListener AttributesMutator#setCacheListener

Expiration

RegionTimeToLive [default: no expiration]

Expiration configuration for the entire region based on the lastModifiedTime.
setRegionTimeToLive {} AttributesMutator#setRegionTimeToLive}

RegionIdleTimeout [default: no expiration]

Expiration configuration for the entire region based on the lastAccessedTime.
setRegionIdleTimeout {} AttributesMutator#setRegionIdleTimeout}

EntryTimeToLive [default: no expiration]

Expiration configuration for individual entries based on the lastModifiedTime.
setEntryTimeToLive {} AttributesMutator#setEntryTimeToLive}

EntryIdleTimeout [default: no expiration]

Expiration configuration for individual entries based on the lastAccessedTime.
setEntryIdleTimeout {} AttributesMutator#setEntryIdleTimeout}

Storage

InitialCapacity [default: 16]

The initial capacity of the map used for storing the entries.
RegionAttributes#getInitialCapacity

LoadFactor [default: 0.75]

The load factor of the map used for storing the entries.
RegionAttributes#getLoadFactor

ConcurrencyLevel [default: 16]

The allowed concurrency among updates to values in the region is guided by the concurrencyLevel, which is used as a hint for internal sizing. The actual concurrency will vary. Ideally, you should choose a value to accommodate as many threads as will ever concurrently modify values in the region. Using a significantly higher value than you need can waste space and time, and a significantly lower value can lead to thread contention. But overestimates and underestimates within an order of magnitude do not usually have much noticeable impact. A value of one is appropriate when it is known that only one thread will modify and all others will only read.
setConcurrencyLevel {}

StatisticsEnabled [default: false]

Whether statistics are enabled for this region. The default is disabled, which conserves on memory.
setStatisticsEnabled {}
