Package pkg/cache provides a cache implementation with support for multiple eviction policies, including: LRU, Segmented LRU, LFU, and TinyLFU.
Other notable features include:
Configurable eviction callback w/support for both synchronous and asynchronous processing
Item Expiry/TTL
Improved Key Caching
Key caching has been refactored to utilize the new cache package.
Added support for a shared intermediate key cache. When enabled, and session caching disabled, caching performance mirrors that of the legacy session cache.
Smaller caches (capacity < 100) automatically default to synchronous eviction process to help prevent memlock exhaustion in low memory environments (e.g. AWS Lambda).
Session Caching
Session caching has also been refactored using the new cache package.
Also...
Removed the deprecated SessionCacheEngine policy option.
Removed the mango cache dependency
Tracing Benchmarks
A new integrationtest/tracing package for benchmarking the performance of the SessionFactory class and
its dependencies. It compares Metastore and KMS access patterns with different cache configurations by playing back access traces.
