Build a three-layer transformation from raw JSON events in Postgres to a sessionized, aggregated daily mart in ClickHouse.
Thread started: 019d6db5-2b98-7581-9cbb-83161a1d5443
Turn started.
I’m going to inspect the workspace to find the existing Postgres/ClickHouse setup, ingestion code, and any migration or dashboard-related files so I can wire this through end to end.

The container is minimal, so I’m falling back to `find` and broad filesystem inspection to locate the app and any database compose/migration files.

The rebuild is running against live Postgres and ClickHouse now. I’m watching the load and will correct any query/type issues before verifying the final mart numbers.
The first non-interactive run isn’t yielding output cleanly, so I’m checking the database state directly and then I’ll rerun the rebuild with a PTY if needed to capture the exact failure.

I found the hang: `CLICKHOUSE_URL` is the HTTP endpoint on `8123`, while `clickhouse-client` needs the native TCP port. I’m correcting the script to translate that cleanly and then rerunning the load.

The load got far enough to expose the remaining issue: `psql` is emitting the null marker as `\\N` instead of `\N`, which ClickHouse rejects. I’m fixing that null serialization and rerunning the rebuild.

We have a bunch of JSON event data sitting in Postgres. We need to get it into ClickHouse so we can build dashboards on daily session activity.
The events are in the `raw.events` table and each row has a JSONB `payload` column with things like session_id, event_type, user_id, and value.
Can you set this up so we have a nice daily summary we can query?

Postgres seeded with raw JSONB events (session_id, event_type, user_id, value). ClickHouse running but empty.
Build staging, intermediate, and mart layers from raw JSON events
