Question

A media company streams clickstream events into a single Amazon Kinesis Data Firehose delivery stream. The analytics team needs the raw JSON events archived in Amazon S3 for long-term batch processing, while the operations team needs the same events delivered in near real time to an Amazon OpenSearch Service domain for live dashboards. The data engineer wants the lowest-operational-overhead solution that guarantees both teams receive every event. What should the engineer do?

Accepted Answer

Configure a single Firehose delivery stream to OpenSearch Service and enable the built-in S3 backup option set to 'AllData' so all records are also written to S3.

Answer

Send events to a Kinesis Data Stream, then attach two separate Firehose delivery streams as consumers — one targeting S3 and one targeting OpenSearch Service.

Answer

Configure the Firehose stream to deliver to S3, then use S3 event notifications to trigger a Lambda function that indexes each object into OpenSearch Service.

Answer

Configure the Firehose stream to deliver to OpenSearch Service and rely on OpenSearch snapshots to S3 to satisfy the archival requirement.
