Release Notes

cache2k/cache2k (org.cache2k:cache2k-api)

v2.6.1.Final: "Cogee Beach"

Compare Source

This change log lists the changes since 2.6.0.Final.

Fixes and Improvements

• Timer: Reduce scheduler events
• Timer: Correct scheduling time if an earlier expiry is inserted. Maximum lag time criteria was not met in this case.
• Timer: Rare case if only one cache entry with TTL and regular updates is used, leeds to continuous increase of scheduling events

v2.6.0.Final: "Cogee Beach"

Compare Source

This change log lists the changes since 2.4.1.Final.

New and Noteworthy

• Idle scan: an efficient expire after access / time to idle alternative, Github issue #​39
• Lots of cleanup and housekeeping with some minor changes possibly breaking compatibility
• Test coverage improvement and removal of unused code
• Cache disable support, Github issue #​74
• Continuous Android testing

Updated benchmarks comparing with Caffeine 3.0.5, and EHCache3 3.9.6

Possible breakages

Changes that may break existing applications.

• Spring support: SpringCache2kManager.defaultSetup throws IllegalStateException if not called before caches are added
• Spring support: SpringCache2kManager.defaultSetup throws IllegalStateException if called twice
• EXPIRY_NOT_ETERNAL constant removed from Cache2kConfig
• Fixed generic typing issues in org.cache2k.config package
• Sechduler.schedule uses delay duration instead of absolute time
• TimeReference.millis() renamed to ticks() and additional conversion methods to support other time resolutions than milliseconds
• Safety gap system property for sharp timeout changed to: org.cache2k.sharpExpirySafetyGapMillis
• Removed capability to modify internal constants via Tunable
• removed SpringCache2kCacheManager.setCaches(Collection<Cache2kConfig<?, ?>> cacheConfigurationList)
• Corrected signature BulkCacheLoader.BulkCallback.onLoadFailure(Set, Exception) to onLoadFailure(Iterable, Exception)
• Cache.expireAt() and MutableCacheEntry.setExpiryTime(): the maximum expiry time is capped by the specified expireAfterWriteDuration, this aligns the behavior with the ExpiryPolicy. The rationale is, that an (application) user, when setting expireAfterWrite expects that this duration is never exceeded.

API Changes

• Added CacheClosedException
• Added CacheEventListenerException

Fixes and Improvements

• Eviction improvements, minimal change to improve eviction, See issue comment
• eternal(true/false) / MutableEntry.setExpiryTime: Expiry can be modified, although no other expiry setting is present, or in other words: the timer support is available by default. If eternal(true) is configured, timer support is disabled and Cache.invoke / MutableEntry.setExpiryTime or Cache.expireAt cannot be used
• Cache.invoke / MutableEntry.setExpiryTime: has no effect if entry is not existing
• Cache.invoke / MutableEntry.getExpiryTime always returns positive time value
• CI tests with Android API level 26 and API level 30
• Expiry timer: handle time values close up to Long.MAX_VALUE - 1 without overflow
• Support Duration for duration parameters in the Cache2kBuilder
• Config section InternalConfig in cache2k-core for specific tuning values that should not be exposed in the public API
• Spring support: SpringCache2kManager.setDefaultCacheNames() added
• Spring support: SpringCache2kManager.addCache(String, Function)
• Spring support: SpringCache2kCacheManager.getCache aligned with interface contract: returns null if unknown cache name is requested
• CacheClosedListener: Wait for CompletableFuture
• Simplify integrity checking, remove integrity state from toString output
• API: add/correct @​Nullable annotations in ExpiryPolicy and AsyncCacheLoader
• Cache.invoke: Set expiry time correctly for exception propagation, in case setException and setExpiry is used atomically
• CacheInfo.getExpiryAfterWriteTicks, CacheInfo.getTimeReference(): added
• CacheControl.getCapacityLimit returns maximum weight correctly when weigher is present
• JCache: simplify implementation with access expiry and Cache.getAll
• JCache: Corrected access expiry handling for Cache.invoke / Cache.invokeAll

Non Functional Improvements

• Some tests migrated to JUnit 5 and AspectJ
• Various documentation touch ups
• Documentation and examples for expiry and expiry policy
• Examples for expiry policy in ExpiryPolicyExampleTest unit test
• Documentation improvements, fixed many typos and grammar errors in the API package

v2.4.0.Final: "Port Philip"

Compare Source

This change log lists the changes since 2.2.1.Final.

New and Noteworthy

This targets details to improve performance of big caches in multi core environments and minimizing the CPU impact on monitoring and frequent statistic polls.

Updated benchmarks comparing with Caffeine 3.0.4, and EHCache3 3.9.6

Fixes and Improvements

• Change default entry capacity to 1802. When the capacity is reported to a monitoring system or otherwise analysed, this serves as a magic number to indicate that the cache capacity is essentially not configured intentionally
• Improved hit counter accuracy for statistics, see: https://github.com/cache2k/cache2k/issues/150
• Improved statistics retrieval. When requesting the statistics, e.g. for micrometer export, no expensive operations are performed any more and no cache wide locking is done. In consequence statistics can be retrieved more frequently without big effect on the running application. Since there is no cache wide lock, statistics counters can have inconsistencies, e.g. the inserted and removed entries might not match exactly with the current size.
• Eviction throughput improvement. The Clock-Pro ghost/history table is limited to 3K entries. Profiling showed that the big ghost table attributed to lower performance with bigger cache sizes (1 million entries) and did not contribute significantly to a better hitrate.
• Various code quality improvements

API Breakages

• MutableCacheEntry.getValueOrNull: removed, since wrongly introduced in version 2.0.

v2.2.1.Final: "Twofold Bay"

Compare Source

This change log lists the changes since 2.2.0.Final.

Fixes and Improvements

• Cache.entries: throws IlliegalStateException if remove is called twice on the iterator.
• Cache.asMap: aligned to the map contract, equals, hashCode cooperate with arbitrary maps,
  toString is implemented identical to Java maps (e.g. HashMap)

Compare Source

This change log lists the complete changes since the last stable version 2.0.0.Final.

New and Noteworthy

• Bulk support: New interfaces BulkCacheLoader and AsyncBulkCacheLoader which are used by the cache operations getAll, loadAll, reloadAll and invokeAll. The will get more optimizations and improvements in the next development releases. GH#166
• CoalescingBulkLoader: combines multiple requests into a bulk requests or limits
  bulk requests to a maximum size. Recommended when using a bulk loader and refresh ahead.
  The CoalescingBulkLoader resides in the separate jar cache2k-addon.

Deprecated methods were removed (see below).

API changes

• Improve API of Feature
• Async loader: add cache to the load context
• Remove deprecated org.cache2k.integration package
• Remove deprecated methods Cache.loadAll, Cache.reloadAll with CacheOperationCompletionListener
• Remove deprecated classes AdvancedKeyValueSource, KeyValueStore
• The deprecation flag for expireAt is removed. We keep this method
• Remove unused org.cache2k.spi.Cache2kExtensionProvider

Fixes and Improvements

• cache2k-api / Modules: export org.cache2k.annotation for Nullable etc.
  Improved new bulk loader support.
• Improve entry processor performance, GH#170
• Consistent exception handling for Cache.computeIfAbsent, GH#171
• Support for AutoClosable for async loaders
• Cache.asMap(): Align exception handling computeIfPresent, compute with ConcurrentMap contract
