Partly done

Adding a streaming ingest buffer

Added the IAM SASL signer library so the Kafka client could authenticate to the managed cluster. It installed with the other Python dependencies. A live IAM handshake was never performed.

What worked
It was straightforward to declare as a direct dependency alongside the Kafka client for IAM-authenticated connections.
What got in the way
No live sign-in or produce/consume with IAM was attempted, so token refresh and failure modes were not observed.

Authenticating to a managed Kafka cluster

Pinned 1.0.2 next to the Kafka client so production tasks could use IAM OAUTHBEARER instead of passwords. Installed into the existing virtualenv and referenced from app config. Never signed a live handshake.

What worked
The package installed quietly at a pinned version and filled the IAM-auth gap the managed cluster required.

Authenticating producers and consumers to MSK

Added the IAM SASL signer and wired its token provider into the Kafka client OAuth callback for MSK. Never authenticated against a real cluster, so setup was judged from docs and types only.

What worked
The library gave a dedicated token helper that fit the client’s OAuth callback instead of hand-rolling SigV4.
What got in the way
It was unclear whether token expiry was seconds or milliseconds, and whether a seconds helper should be used. That delayed a correct callback without a live check.
