Detailed Description

template<class TKey, class TValue>
class Apache::Geode::Client::AttributesFactory< TKey, TValue >

Factory class to create instances of RegionAttributes.

An AttributesFactory 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 CreateRegionAttributes 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 preset RegionAttributes.

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

[default: null]

User-implemented plug-in for loading data on cache misses.
see SetCacheLoader, RegionAttributes.CacheLoader

[default: null]

User-implemented plug-in for intercepting cache modifications, e.g. for writing to an external data source.
see SetCacheWriter, RegionAttributes.CacheWriter

[default: null]

User-implemented plug-in for receiving and handling cache-related events.
see SetCacheListener, RegionAttributes.CacheListener

[default: null]

User-implemented plug-in for custom partitioning.

Expiration

RegionTimeToLive [default: no expiration]

Expiration configuration for the entire region based on the lastModifiedTime ( CacheStatistics.LastModifiedTime ).
see SetRegionTimeToLive, RegionAttributes.RegionTimeToLive, AttributesMutator.SetRegionTimeToLive

RegionIdleTimeout [default: no expiration]

Expiration configuration for the entire region based on the lastAccessedTime ( CacheStatistics.LastAccessedTime ).
see SetRegionIdleTimeout, RegionAttributes.RegionIdleTimeout, AttributesMutator.SetRegionIdleTimeout

EntryTimeToLive [default: no expiration]

Expiration configuration for individual entries based on the lastModifiedTime ( CacheStatistics.LastModifiedTime ).
see SetEntryTimeToLive, RegionAttributes.EntryTimeToLive, AttributesMutator.SetEntryTimeToLive

EntryIdleTimeout [default: no expiration]

Expiration configuration for individual entries based on the lastAccessedTime ( CacheStatistics.LastAccessedTime ).
see SetEntryIdleTimeout, RegionAttributes.EntryIdleTimeout, AttributesMutator.SetEntryIdleTimeout

Storage

InitialCapacity [default: 16]

The initial capacity of the map used for storing the entries.
see SetInitialCapacity, RegionAttributes.InitialCapacity

LoadFactor [default: 0.75]

The load factor of the map used for storing the entries.
see SetLoadFactor, RegionAttributes.LoadFactor

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.
