Feature Request: Add a Kinesis source

Feature request

Is your feature request related to a problem?

PostHog had a plugin for this before: https://github.com/PostHog/posthog-kinesis-plugin

Describe the solution you'd like

An option to add Kinesis as a source directly.

Describe alternatives you've considered

• Set up Kinesis → S3 export using AWS Kinesis Data Firehose
• Use a self-managed S3 source to import the data
• If you need to ingest events (rather than just querying data in the warehouse), you have two options:
  • A: Historical migration: Export from Kinesis to S3 in JSONL format, then use the SDK or batch API endpoint with historical migrations
  • B: Real-time webhook: Set up a Lambda function that reads from Kinesis, then have the Lambda function send events to the Capture API

Debug info

null

Start by reviewing the linked posthog-kinesis-plugin and PostHog's existing S3 source, historical migration, and Capture API documentation to understand the relevant ingestion paths. Done should mean users can configure Kinesis as a direct source without the listed Firehose, Lambda, or manual-export workarounds, with the required behavior and scope agreed first.
