Final answer:
The maximum batch size for a Kinesis trigger is 500 records.
Step-by-step explanation:
The maximum batch size for a Kinesis trigger is 500 records. Kinesis is a service provided by Amazon Web Services (AWS) that allows for the processing of large streams of data in real time. When a Kinesis trigger is fired, it retrieves a batch of records from the stream and processes them. The maximum batch size determines the number of records that can be processed in one trigger execution.
