Configuration and Performance
=============================
+Files Processing Configuration
+""""""""""""""""""""""""""""""
+The PM Mapper consumes the 3GPP XML files from DMaaP-DR, and processes them. It is possible to process it in parallel.
+In order to parallel processing, new configuration env has been introduced:
+
+- PROCESSING_LIMIT_RATE (optional, default value: 1) - allows to limit the rate of processing files through channel.
+
+- THREADS_MULTIPLIER (optional, default value: 1) - allows to specify multiplier to calculate the amount of threads.
+
+- PROCESSING_THREADS_COUNT (optional, default value: number of threads available to JVM) - allows to specify number of threads that will be used for files processing.
+
+
+Envs should be specified in section "envs:" in blueprint. Example part of blueprint configuration:
+
+::
+
+ ...
+ pm-mapper:
+ type: dcae.nodes.ContainerizedServiceComponentUsingDmaap
+ interfaces:
+ cloudify.interfaces.lifecycle:
+ create:
+ inputs:
+ ports:
+ - '8443:0'
+ - '8081:0'
+ envs:
+ PROCESSING_LIMIT_RATE: "1"
+ THREADS_MULTIPLIER: "2"
+ PROCESSING_THREADS_COUNT: "3"
+ relationships:
+ - type: dcaegen2.relationships.subscribe_to_files
+ target: pm-feed
+ - type: dcaegen2.relationships.publish_events
+ target: pm-topic
+ ...

PM Mapper Filtering
"""""""""""""""""""
The PM Mapper performs data reduction, by filtering the PM telemetry data it receives.
