+KINESIS INPUT OPERATOR
+=====================
+
+### Introduction
+
+The kinesis input operator consumes data from the partitions of a Kinesis shard(s) for processing in Apex. 
+The operator is fault-tolerant, scalable and supports input from multiple shards of AWS kinesis streams in a single operator instance.
+
+### Kinesis Input Operator
+
+Package: `com.datatorrent.contrib.kinesis`
+
+Maven artifact: [malhar-contrib](https://mvnrepository.com/artifact/org.apache.apex/malhar-contrib)
+
+### Pre-requisites
+
+This operator uses the AWS kinesis java sdk version 1.9.10.
+
+### AbstractKinesisInputOperator
+
+This is the abstract implementation that serves as base class for consuming records from AWS Kinesis streams.

+
+#### Configuration properties
+
+-   ***accessKey*** - String[]
+    -   Mandatory Parameter.
+    -   Specifies the AWS credentials AccessKeyId.
+    
+-   ***secretKey*** - String[]
+    -   Mandatory Parameter.
+    -   Specifies the AWS credentials SecretAccessKey.
+
+-   ***streamName*** - String[]
+    -   Mandatory Parameter.
+    -   Specifies the name of the stream from where the records to be accessed.
+    
+-   ***strategy*** - PartitionStrategy
+    -   Operator supports two types of partitioning strategies, `ONE_TO_ONE` and `MANY_TO_ONE`.
+    
+        `ONE_TO_ONE`: If this is enabled, the AppMaster creates one input operator instance per kinesis shard partition. So the number of shard partitions equals the number of operator instances.
+        `MANY_TO_ONE`: The AppMaster creates K = min(initialPartitionCount, N) Kinesis input operator instances where N is the number of shard partitions. If K is less than N, the remaining shard partitions are assigned to the K operator instances in round-robin fashion. If K is less than initialPartitionCount, the AppMaster creates one input operator instance per shard partition. For example, if initialPartitionCount = 5 and number of shard partitions(N) = 2 then AppMaster creates 2 Kinesis input operator instances.
+        Default Value = `PartitionStrategy.ONE_TO_ONE`.
+
+-   ***initialPartitionCount*** - Integer
+    -   When the MANY_TO_ONE partition strategy is enabled, this value indicates the number of Kinesis input operator instances. 
+        Default Value = 1.
+
+-   ***initialOffset*** - InitialOffset
+    -   Indicates the type of offset i.e, `EARLIEST` or `LATEST`. 
+        `LATEST` => Consume new record(s) from latest offset in the shard. 
+        `EARLIEST` => Consume all record(s) available in the shard.
+        Default value = `InitialOffset.LATEST`
+        
+-   ***repartitionInterval*** - Long
+    -   Interval specified in milliseconds. This value specifies the minimum time required between two repartition actions. 
+        Default Value = 30 Seconds.
+
+-   ***repartitionCheckInterval*** - Long
+    -   Interval specified in milliseconds. This value specifies the minimum interval between two stat checks.
+        Default Value = 5 Seconds.
+
+-   ***maxTuplesPerWindow*** - Integer
+    -   Controls the maximum number of records emitted in each streaming window from this operator. Minimum value is 1. 
+        Default value = `MAX_VALUE`
+
+-   ***holdingBufferSize*** - Long
+    -   Indicates the maximum number of messages kept in memory for emitting.
+        Default value = 1024.
+
+-   ***windowDataManager*** - WindowDataManager
+    -   If set to a value other than the default, such as `FSWindowDataManager`, specifies that the operator will process the same set of messages in a window before and after a failure. This is important but it comes with higher cost because at the end of each window the operator needs to persist some state with respect to that window.
+        Default value = `WindowDataManager.NoopWindowDataManager`.
+
+#### Abstract Methods
+
+`T getTuple(Record record)`: Converts the Kinesis Stream record(s) to tuple.
+`void emitTuple(Pair<String, Record> data)`: This method emits tuples extracted from AWS kinesis streams.
+
+#### Ports
+
+`outputPort <T>`: Tuples extracted from Kinesis streams in form of records are emitted through this port.
+
+### KinesisConsumer
+
+This is an abstract implementation of Kinesis consumer. It sends the fetch
+requests from AWS kinesis streams to Kinesis partitions. For each request,
+it receives the set of records and stores them into the buffer which is
+ArrayBlockingQueue.
+
+
+### ShardManager
+
+This is an interface for offset management and is useful when consuming data
+from specified offsets. Updates the offsets for all the kinesis partitions
+periodically. Below is the code snippet:
+
+```java
+public class ShardManager
+{
+  public Map<String, String> loadInitialShardPositions();
+  public Map<String, String> loadInitialShardPositions();
+  public void updatePositions(Map<String, String> shardPositions);
+}
+```
+
+### Partitioning
+
+The logical instance of the KinesisInputOperator acts as the Partitioner
+as well as a StatsListener. This is because the
+AbstractKinesisInputOperator implements both the
+com.datatorrent.api.Partitioner and com.datatorrent.api.StatsListener
+interfaces and provides an implementation of definePartitions(...) and
+processStats(...) which makes it auto-scalable.
+
+#### Response processStats(BatchedOperatorStats stats)
+
+The application master invokes this method on the logical instance with
+the stats (tuplesProcessedPS, bytesPS, etc.) of each partition.
+Re-partitioning happens based on whether any new Kinesis streams are added/modified 
+or based on kinesis shards stats with respective upper bounds.
+
+#### DefinePartitions
+
+Based on the repartitionRequired field of the Response object which is
+returned by processStats(...) method, the application master invokes
+definePartitions(...) on the logical instance which is also the
+partitioner instance. Dynamic partition can be disabled by setting the
+parameter repartitionInterval value to a negative value.
+
+
+#### KinesisStringInputOperator
+This class extends from AbstractKinesisInputOperator and defines the `getTuple()` method which extracts byte array from Kinesis record.
+
+#### Ports
+`outputPort <byte[]>`: Tuples extracted from Kinesis Streams are emitted through this port.
+
+### Application Example
+
+This section builds an Apex application using Kinesis input operator.
+Below is the code snippet:
+
+```java
+@ApplicationAnnotation(name="KinesisApp")
+public class ExampleApplication implements StreamingApplication
+{
+
+  @Override
+  public void populateDAG(DAG dag, Configuration conf)
+  {
+    KinesisStringInputOperator inputOperator = dag.addOperator("kinesisInput", new KinesisStringInputOperator());
+    ConsoleOutputOperator outputOperator = dag.addOperator("Console", new ConsoleOutputOperator());
+    dag.addStream("kinesis-to-console", inputOperator.outputPort, outputOperator.input);
+  }
+}
+```
+Below is the configuration for “KINESIS-STREAM-NAME” Kinesis stream name:
+
+```xml
+<property>
+  <name>dt.operator.kinesisInput.prop.streamName</name>
+  <value>KINESIS-STREAM-NAME</value>
+</property>
+<property>
+  <name>dt.operator.kinesisInput.prop.accessKey</name>
+  <value>ACCESSKEY</value>
+</property>
+<property>
+  <name>dt.operator.kinesisInput.prop.secretKey</name>
+  <value>SECRETKEY</value>
+</property>
+<property>
+  <name>dt.operator.kinesisInput.prop.endPoint</name>
+  <value>ENDPOINT</value>
+</property>
+```
