AWS Service Update – Informational message: [RESOLVED] Increased delays in event processing from Streams

Between 4:05 PM PST and 5:20 PM PST, customers using Lambda functions to process events from Kinesis Data Streams and DynamoDB Streams experienced significant delays in event processing for a subset of functions in the EU-WEST-1 Region. The issue has been resolved and the service is operating normally. The backlogged events will be processed by the function over the next few hours as per the retry policy on the event source mapping on the affected functions.
