show me someone who claims to understand DynamoDB pricing and I’ll show you a liar
Screenshot: Write capacity unit (WCU): Each API call to write data to your table is a write request. For items up to 1 KB in size, one WCU can perform one standard write request per second. Items larger than 1 KB require additional WCUs. Transactional write requests require two WCUs to perform one write per second for items up to 1 KB. For example, a standard write request of a 1 KB item would require one WCU, a standard write request of a 3 KB item would require three WCUs, and a transactional write request of a 3 KB item would require six WCUs. Replicated write capacity unit (rWCU): When using DynamoDB global tables, your data is written automatically to multiple AWS Regions of your choice. Each write occurs in the local Region as well as the replicated Regions.
