⚡Amazon Kinesis

NEW

Also known as: Kinesis

A managed AWS service for real-time data streaming, ingestion, and analytics at scale.

DESCRIPTION

Amazon Kinesis provides real-time data pipelines with services for streams, delivery, analytics, and video. Kinesis Data Streams offers sharded ingestion with low-latency consumption. Kinesis Data Firehose delivers to S3, Redshift, and Elasticsearch with optional transformation. Kinesis Data Analytics runs SQL or Apache Flink applications over streaming data. It integrates with AWS security, monitoring, and serverless services for operational simplicity.

TOP QUESTIONS

What are the core components of Amazon Kinesis?

Kinesis Data Streams handles ingestion, Data Firehose handles delivery, Data Analytics provides SQL or Flink-based processing, and Video Streams handles media ingestion.

Category: Overview

How do Kinesis shards affect throughput?

Each shard provides a fixed write and read capacity. Scaling throughput requires resharding by splitting or merging shards.

Category: Performance

When should I use Kinesis Data Firehose?

Use Firehose for managed delivery to destinations like S3 or Redshift with minimal ops. It supports transformations and automatic scaling without shard management.

Category: Guidance

How does Kinesis compare to Apache Kafka?

Kinesis is fully managed with shard-based scaling; Kafka offers more control and ecosystem flexibility. Choice depends on managed convenience versus platform portability.

Category: Comparison

What are common cost pitfalls with Kinesis?

Overprovisioned shards and excessive enhanced fan-out consumers can drive costs. Optimize retention and batching to control spend.

Category: Mistakes

Does Kinesis support exactly-once processing?

Kinesis provides at-least-once delivery, while exactly-once semantics depend on downstream processing and idempotent sinks.

Category: Guarantees

How do I monitor Kinesis health?

Use CloudWatch metrics like IteratorAgeMilliseconds, IncomingBytes, and ReadProvisionedThroughputExceeded. Set alarms and analyze enhanced metrics if enabled.

Category: Operations

Can I run Apache Flink on Kinesis?

Yes, via Kinesis Data Analytics for Apache Flink, enabling event-time processing, windows, and stateful operators.

Category: Capabilities

How does Kinesis integrate with Lambda?

Lambda can consume from Kinesis streams, handling batch events with retry and checkpointing coordinated via sequence numbers.
