This very simple library can be used to write data to an Amazon Kinesis stream.
The data that is supposed to be written to the Kinesis Stream has to be an
How to use it
Include the library in your project's
libraryDependencies += "com.audienceproject" %% "kinesis-writer" % "3.0.1"
Easiest is to just to provide the Kinesis Stream name and the iterator. The Kinesis client is build for you with the default profile credentials provider. This works great on Amazon EC2.
val it = List( Array[Byte](10, 11, 23), Array[Byte](6, 4, 13) ).toIterator KinesisWriter.write("test-stream", it)
You can also specify a Kinesis client. This is mostly useful when running outside AWS.
val it = List( Array[Byte](10, 11, 23), Array[Byte](6, 4, 13) ).toIterator val client = new AmazonKinesisClient(new ProfileCredentialsProvider("my-custom-profile")) ScalaKinesisWriter.write("test-stream", it, client)
Has code copy pasted from: https://github.com/awslabs/kinesis-aggregation/tree/master/java/KinesisAggregatorV2 due to it not being on maven and manual lib dependencies being subpar.
To make sure that data is successfully consumed on the other side of the Kinesis stream, the maximum record size has empirically been made smaller than what Amazon lists as maximum. Experiments have shown that records the size of (or close) to 1MB can fail to be consumed correctly.
