The equivalent property configuration is as follows: # queryId based routing file appender appender.test-query-routing.type = Routing appender.test-query-routing.name = test-query-routing appender.test-query-routing.routes.type = Routes appender.test-query-routing.routes.pattern = $${ctx:queryId} # default route appender.test-query-routing.routes.test-route-default.type = Route appender.test-query-routing.routes.test-route-default.key = $${ctx:queryId} appender.test-query-routing.routes.test-route-default.app.type = NullAppender appender.test-query-routing.routes.test-route-default.app.name = test-null-appender # queryId based route appender.test-query-routing.routes.test-route-mdc.type = Route appender.test-query-routing.routes.test-route-mdc.name = test-query-routing appender.test-query-routing.routes.test-route-mdc.app.type = RandomAccessFile appender.test-query-routing.routes.test-route-mdc.app.name = test-query-file-appender appender.test-query-routing.routes.test-route-mdc.app.fileName = ${sys:hive.log.dir}/${ctx:sessionId}/${ctx:queryId}.test appender.test-query-routing.routes.test-route-mdc.app.layout.type = PatternLayout appender.test-query-routing.routes.test-route-mdc.app.layout.pattern = %d{ISO8601} %5p %c{2}: %m%n appender.test-query-routing.routes.test-route-mdc.app.filter.type = TestFilter
