[jira] [Comment Edited] (LOG4J2-1010) Injectable context properties

    [ https://issues.apache.org/jira/browse/LOG4J2-1010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15399011#comment-15399011 ]

--------------------------------------------------------------

About avoiding interaction with ThreadContext, note that [ThreadContextMapFilter|https://logging.apache.org/log4j/2.0/log4j-core/xref/org/apache/logging/log4j/core/filter/ThreadContextMapFilter.html] and [ContextMapLookup|https://logging.apache.org/log4j/2.0/log4j-core/xref/org/apache/logging/log4j/core/lookup/ContextMapLookup.html] get values from ThreadContext, but that is fine since that is the "contract" of these classes, that is what they are defined to do. I don't think these need to be changed. If we support additional sources of Context data, we can add filters and lookups for them.

For {{DynamicThresholdFilter}} I think it makes sense to go through the ContextDataInjector rather than querying the ThreadContext.

> It would be useful to have a way to inject context properties into a {{LogEvent}}, as an alternative to {{ThreadContext}}.
> In an asynchronous environment, using ThreadContext as currently implemented is not so useful since JVM threads might not be coupled to the logical flow of the application.
