No write up, but the main reason was reusing the existing database we were comfortable deploying at the time. We were already using FDB for an online aggregation / mutation store for ad-hoc time-series analytics...albeit, a custom layer that we wrote (not RecordLayer).
When RecordLayer launched, I tested it out by building a catalog system that we could evolve and add new services with a single repository of protobuf schemas.
