> On {{aws2-ddb}} endpoint start it constantly checking table status by doing {{DescribeTable}} request.

>         super.doStart();
>         ddbClient = configuration.getAmazonDDBClient() != null ? configuration.getAmazonDDBClient() : createDdbClient();
>         String tableName = getConfiguration().getTableName();
>         LOG.trace("Querying whether table [{}] already exists...", tableName);
>         try {
>             DescribeTableRequest.Builder request = DescribeTableRequest.builder().tableName(tableName);
>             TableDescription tableDescription = ddbClient.describeTable(request.build()).table();

> Key issues with such approach:
>  * it requires to grant {{DescribeTable}} operation for client which provides sensitive information like KMS master key ARN/ID, billing information etc. ([https://docs.aws.amazon.com/amazondynamodb/latest/APIReference/API_DescribeTable.html])
>  * after start and checking table status for being ACTIVE there is no guarantee that it's actually true on doing any other DDB operation with started component. 
> Potential Solution:
> * introduce {{createTable}} configuration parameter and use {{DescribeTable}} only if {{createTable}}=={{true}} (default {{false}})
