+This project contains the Message Queue(MQ) Broker code.
+
+Build and Run
+
+1) Install Apache Maven if you don't have it
+
+ http://maven.apache.org
+
+2) Install Apache Kafka if you don't have it
+
+ http://kafka.apache.org/downloads.html
+
+ Set 'host.name' in Kafka server configuration file to your ip address,
+ Run Zookeeper server and Kafka broker with the configuration file.
+
+3) Build a CloudStack. If you are building first time, then build the stack.
+
+ go to "stack" folder in root directory
+ $ mvn install -Dmaven.test.skip=true
+
+4) Build a .jar file
+
+ $ mvn install -Dmaven.test.skip=true
+
+ - The CloudMessageQueue-0.0.1-SNAPSHOT.jar file will be placed in the "target" folder
+
+5) Run .jar file
+
+ go to "target" folder
+ $ java -jar CloudMessageQueue-0.0.1-SNAPSHOT.jar arg1(MQ CoAP Server Port)
+ arg2(Zookeeper server address) arg3(Zookeeper server port)
+ arg4(kafka server address) arg5(kafka server port) arg6(TLS mode required)
+
+ e.g java -jar CloudMessageQueue-0.0.1-SNAPSHOT.jar 5686 127.0.0.1 2181 127.0.0.1 9092 0
+
+ - Before running a MQ Broker, you should run Zookeeper server and Kafka broker first.
+ - If you want to operate on TLS mode, "CLOUD_CERT_FILE(iotivitycloud.crt)", "CLOUD_KEY_FILE(iotivitycloud.key)"
+ and ROOT_CERT_FILE(rootca.crt) files should be placed in the "target" folder.

+############################# Socket Server Settings #############################
+
+listeners=PLAINTEXT://:9092
+
+# The port the socket server listens on
+port=9092
+
+# Hostname the broker will bind to. If not set, the server will bind to all interfaces
+host.name=localhost
+
+# Hostname the broker will advertise to producers and consumers. If not set, it uses the
+# value for "host.name" if configured. Otherwise, it will use the value returned from
+# java.net.InetAddress.getCanonicalHostName().
+#advertised.host.name=<hostname routable by clients>
+
+# The port to publish to ZooKeeper for clients to use. If this is not set,
+# it will publish the same port that the broker binds to.

+
+############################# Log Basics #############################
+
+# A comma seperated list of directories under which to store log files
+log.dirs=/tmp/kafka-logs
+
+# The default number of log partitions per topic. More partitions allow greater
+# parallelism for consumption, but this will also result in more files across
+# the brokers.
+num.partitions=1
+
+# The number of threads per data directory to be used for log recovery at startup and flushing at shutdown.
+# This value is recommended to be increased for installations with data dirs located in RAID array.
+num.recovery.threads.per.data.dir=1
+
+############################# Log Flush Policy #############################
+
+# Messages are immediately written to the filesystem but by default we only fsync() to sync
+# the OS cache lazily. The following configurations control the flush of data to disk.
+# There are a few important trade-offs here:
+# 1. Durability: Unflushed data may be lost if you are not using replication.
+# 2. Latency: Very large flush intervals may lead to latency spikes when the flush does occur as there will be a lot of data to flush.
+# 3. Throughput: The flush is generally the most expensive operation, and a small flush interval may lead to exceessive seeks.
+# The settings below allow one to configure the flush policy to flush data after a period of time or
+# every N messages (or both). This can be done globally and overridden on a per-topic basis.
+
+# The number of messages to accept before forcing a flush of data to disk
+#log.flush.interval.messages=10000
+
+# The maximum amount of time a message can sit in a log before we force a flush
+#log.flush.interval.ms=1000
+
+############################# Log Retention Policy #############################
+
+# The following configurations control the disposal of log segments. The policy can
+# be set to delete segments after a period of time, or after a given size has accumulated.
+# A segment will be deleted whenever *either* of these criteria are met. Deletion always happens
+# from the end of the log.
+
+# The minimum age of a log file to be eligible for deletion
+log.retention.hours=168
+
+# A size-based retention policy for logs. Segments are pruned from the log as long as the remaining
+# segments don't drop below log.retention.bytes.
+#log.retention.bytes=1073741824
+
+# The maximum size of a log segment file. When this size is reached a new log segment will be created.
+log.segment.bytes=1073741824
+
+# The interval at which log segments are checked to see if they can be deleted according
+# to the retention policies
+log.retention.check.interval.ms=300000
+
+# By default the log cleaner is disabled and the log retention policy will default to just delete segments after their retention expires.
+# If log.cleaner.enable=true is set the cleaner will be enabled and individual logs can then be marked for log compaction.
+log.cleaner.enable=true
+
+############################# Zookeeper #############################
+
+# Zookeeper connection string (see zookeeper docs for details).
+# This is a comma separated host:port pairs, each corresponding to a zk
+# server. e.g. "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002".
+# You can also append an optional chroot string to the urls to specify the
+# root directory for all kafka znodes.
+zookeeper.connect=localhost:2181
+
+# Timeout in ms for connecting to zookeeper
+zookeeper.connection.timeout.ms=6000
