问题描述
错误纯粹是标题.我对从Hazelcast检索到的地图中的containsKey所做的任何调用都收到此特定错误.下面的示例:
The error is purely the title. Any call I do to containsKey in a map retrieved from Hazelcast I get this specific error. Example below:
val structuresMapStore : IMap[ String, Object ] = instance.getMap( MapNames.Structures )
if ( structuresMapStore.containsKey( uuidModel ) ) {
logger.info( "\n\n Server - Dropping map: " + uuidModel + "\n\n" )
structuresMapStore.remove( uuidModel )
instance.getMap( uuidModel ).destroy()
return "SUCCESS"
}
return "FAIL"

当我在if语句中调用containsKey时发生错误.
The error occurs when I call containsKey inside if statement.
推荐答案
在直写的情况下，不允许通过MapStore接口方法进行操作.因为直写映射存储操作在分区线程上运行，并且使用其他基于分区的操作(如Containskey)可能会导致死锁.这就是为什么我们在那里有检查和异常的原因.
It is not allowed to make operations from MapStore interface methods in case of write through. Because writethrough map store operations run on partition thread, and using another partition based operation(like Containskey) can cause deadlock. That is why we have a check and an exception there.
