Ths configuration of function of the plugin follows the serverless documentation.

`yml
functions:
myKinesisHandler:
handler: handler.compute
events:
- stream:
enabled: true
type: dynamodb
arn: arn:aws:dynamodb:eu-west-1:XXXXXX:table/myStream/stream/2018-07-02T19:48:31.121
batchSize: 10
startingPosition: TRIM_HORIZON
`

The configuration of aws.DynamoDBStreams's client of the plugin is done by defining a custom: serverless-offline-dynamodb-streams object in your serverless.yml with your specific configuration.

You could use mhart's Dynalite with the following configuration:

`yml
custom:
serverless-offline-dynamodb-streams:
apiVersion: '2013-12-02'
endpoint: http://0.0.0.0:8000
region: eu-west-1
accessKeyId: root
secretAccessKey: root
skipCacheInvalidation: false
readInterval: 500
`

> arn could be deduce from tableName if your add the key tableName in your function's configuration. Useful if your use dynalite and regularly recreate a new DynamoDBStreams.

`yml
functions:
myKinesisHandler:
handler: handler.compute
events:
- stream:
enabled: true
type: dynamodb
tableName: myTable
