如何启用版本控制？

Question

I'd like to enable versioning for a replicated cache in a locally-running Infinispan server (8.2.4 final, two Infinispan servers form a cluster).

This is documented in the user guide .

Quote:

10.2.5. Configuration

By default versioning will be disabled.

and the user guide contains the following snippet:

<versioning scheme="SIMPLE|NONE" />

I am using locally-running Infinispan servers, the configuration is in clustered.xml.

A fragment thereof:

    <subsystem xmlns="urn:infinispan:server:core:8.2" default-cache-container="clustered">
        <cache-container name="clustered" default-cache="default" statistics="true">
            [...]
            <replicated-cache name="demoCache" mode="ASYNC" >
                <versioning scheme="SIMPLE"/>
            </replicated-cache>

So when I add the versioning element, starting fails with

Caused by: javax.xml.stream.XMLStreamException: ParseError at [row,col]:[186,6]

Message: WFLYCTL0198: Unexpected element '{urn:infinispan:server:core:8.2}versioning' encountered

The XML element versioning indeed exists in urn:infinispan:config:8.2 , but not in urn:infinispan:server:core:8.2 (which is used in clustered.xml).

urn:infinispan:config:8.2 is defined in infinispan-server-8.2.4.Final/docs/schema/infinispan-config-8.2.xsd .

urn:infinispan:server:core:8.2 is defined in infinispan-server-8.2.4.Final/docs/schema/jboss-infinispan-core_8_2.xsd

How can I enable (cluster aware) versioning when running Infinispan as a separate server?

远程使用Infinispan时，版本控制没有意义，因为版本控制仅用于检测具有可重复读取事务的写入歪斜情况，并且该功能实际上不适用于服务器模式下的用户。
