Question

可以从EntryProcessor的process（）方法中访问IMap或其他Hazelcast分布式数据结构（如AtomicLong）吗？

我得到以下异常：

java.util.concurrent.ExecutionException: java.lang.IllegalThreadStateException: Thread[hz.Alcatraz-ANP-Sys-HAZLE-2.actiance.local.partition-operation.thread-5,5,Alcatraz-ANP-Sys-HAZLE-2.actiance.local] cannot make remote call: com.hazelcast.concurrent.lock.operations.LockOperation@3229190f

我正在使用Hazelcast版本3.3

Answer 1

您可以访问其他数据结构，但需要确保它们与当前处理的条目位于同一数据分区中。这意味着您可以使用（例如）数据关联来将所有数据固定在同一分区中。

虽然不可能在不同分区之间共享IAtomicLong。

PS：你也不应该改变当前处理过的条目之外的其他数据，因为它可能会在不同节点之间陷入僵局。

从EntryProcessor访问IMap
