Do AWS DynamoDb streams consume the table's read capacity

I am reading into DynamoDb and DynamoDb Streams and I cannot find a place where is says whether having a DynamoDb stream is consuming read capacity from the stream's table.

I am aware that Streams have their own capacity units that that cost (see the first link I posted), but I also want to know whether I should increase my table's read capacity after I enable a stream for it.

No, DynamoDB streams will never consume Read capacity units from your table. You can consider this as a transaction log enabled on top of your DynamoDB table which can be used to capture every modification to items in the table.

Using DynamoDB Streams won't throttle/exhaust your read capacity.

In essence, DynamoDB Streams are "transactional logs" for DynamoDB tables.

You pay separataley for Read Capacity Units (RCUs) and Read Request Units (bottom of the page).
