When an item in the table is modified, StreamViewType determines what information is written to the stream for this table.
Example
import * as eventsources from 'aws-cdk-lib/aws-lambda-event-sources';
import * as dynamodb from 'aws-cdk-lib/aws-dynamodb';
declare const fn: lambda.Function;
const table = new dynamodb.Table(this, 'Table', {
partitionKey: {
name: 'id',
type: dynamodb.AttributeType.STRING,
},
stream: dynamodb.StreamViewType.NEW_IMAGE,
});
fn.addEventSource(new eventsources.DynamoEventSource(table, {
startingPosition: lambda.StartingPosition.LATEST,
metricsConfig: {
metrics: [lambda.MetricType.EVENT_COUNT],
}
}));
