Yes, you nailed it. Old data is important sometimes, like when a problem has been identified and investigated, but most workloads are looking at the current state of the system. So we keep the hot data cached locally (not nas/ebs) and s3 is always the source of truth. DuckDB over parquet files on a local ssd is fast enough you don’t need a traditional database.
We are using DuckLake with a “lakehouse” architecture for the observability agent.
