SPI has been removed due to new Ignite page memory architecture [1]. The swapping tier can only be used if a swapping file is set via MemoryPolicyConfiguration.swapFilePath property.

• localPromote - removed due to new Ignite page memory architecture [1]

CacheEntry

updateTime method was removed

CacheMetrics

The following methods were removed as part of a migration to page memory architecture [1]. New MemoryMetrics interface has been introduced in order to monitor memory usage in runtime [3].

• getOverflowSize

• getOffHeapMaxSize

• getSwapGets

• getSwapPuts

• getSwapRemovals

• getSwapHits

• getSwapMisses

• getSwapEntriesCount

• getSwapSize

• getSwapHitPercentage

• getSwapMissPercentage

CacheMemoryMode

Enumeration has been removed due to new Ignite page memory architecture [1]. Offheap is used as the main storage tier with an ability to enable Java heap caching via CacheConfiguration.onheapCacheEnabled property.

CacheAtomicWriteOrderMode

Enumeration has been removed because CLOCK mode is no longer supported for ATOMIC cache.

CachePeekMode

SWAP value has been removed due to new Ignite page memory architecture [1]. The swapping tier can only be used if a swapping file is set via MemoryPolicyConfiguration.swapFilePath property.

@AffinityKeyMapped annotation

No longer allowed on methods.

FairAffinityFunction

Implementation has been removed due to well-known problems with co-location between caches on different versions of cluster topology. Use RendezvousAffinityFunction.

RandomEvictionPolicy

Implementation has been removed with no replacement.

AffinityNodeHashResolver

Interface has been removed. Use IgniteConfiguration.consistentId property.

RandomEvictionPolicy

Implementation has been removed with no replacement.
