4.3. About Local Mode
4.3.1. Local Mode Operations
Using JBoss Data Grid's local mode instead of a map provides a number of benefits.
Caches offer features that are unmatched by simple maps, such as:
- Write-through and write-behind caching to persist data.
- Entry eviction to prevent the Java Virtual Machine (JVM) running out of memory.
- Support for entries that expire after a defined period.
JBoss Data Grid is built around a high performance, read-biased data container that uses techniques such as optimistic and pessimistic locking to manage lock acquisitions.
JBoss Data Grid also uses compare-and-swap and other lock-free algorithms, resulting in high throughput multi-CPU or multi-core environments. Additionally, JBoss Data Grid's Cache API extends the JDK's
ConcurrentMap
, resulting in a simple migration process from a map to JBoss Data Grid.
