…fusing, needs scaling recommendations: - Distinguish between Catalog store (Postgres db) and Catalog service (API and cache for the store). - Add scaling recommendations for each. - Resolve conflicting scaling info, remove duplicated scaling info from storage-engine.md.

Looks good. Just to sum up, we're now distinguishing between the Catalog store and the Catalog service. @reidkaufmann, do you feel this is sufficient?
| The Catalog store is a PostgreSQL-compatible database that persistently stores metadata. | ||
| Scaling strategies depend on your chosen PostgreSQL implementation. | ||
| All support [vertical scaling](#vertical-scaling), and most support | ||
| [horizontal scaling](#horizontal-scaling) for redundancy and failover. |

Might be worth noting that "an underprovisioned catalog store can result in write outages." @marcdavoli I think it would be good to give a concrete example of what we do in Cloud Dedicated. Can you suggest something here.
| object storage services used to run the object store. | ||
| Most support [horizontal scaling](/influxdb3/clustered/admin/scale-cluster/#horizontal-scaling) | ||
| for redundancy, failover, and increased capacity. | ||
|
|
||
| ### Compactor | ||
|
|
||
| The Compactor processes and compresses partitions in the [Object store](#object-store) | ||
| to continually optimize storage. | ||
| It then updates the [Catalog](#catalog) with locations of compacted data. | ||

Probably should say there should be one pod and to utilize vertical scaling.
