[infinispan-issues] [JBoss JIRA] (ISPN-5553) Functional Java 8 API

Galder Zamarreño created ISPN-5553: -------------------------------------- Summary: Functional Java 8 API Key: ISPN-5553 URL: https://issues.jboss.org/browse/ISPN-5553 Project: Infinispan Issue Type: Feature Request Reporter: Galder Zamarreño Assignee: Galder Zamarreño Fix For: 8.0.0.Final Infinispan 8 is baselining on Java 8 and that enables a more advanced , functional, APIs to be built instead of relying on the traditional Map-like APIs. Such APIs, taking lambda functions, can improve on the current APIs in the following way: * Being able to provide a write operation, where the operation is defined as a lambda, better enables conditional (CAS) like operations that are based in functions other than equality, e.g. version equality. If this functions can be executed atomically, they provide a better solution for Hot Rod version-based replace operations that currently can cause some weird behaviour (ISPN-4972) * When operations are defined as lambdas, it's easier to move towards a model that tracks/replicates operations leading to state, rather than replicating state itself. This makes it easier to implement more-efficiently replicated alternative data structures, such as counts, lists...etc, and paths the way towards CRDTs, particularly CmRDT (Commutative Replicated Data Types) or operation-based CRDTs. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
