Has anyone had any production experience using Foreign Data Wrappers to combine the performance of different database types into one facade? IE is it actually reasonable (and something people do) to hit bigquery for a large aggregation, Neo4j for a graph query, and Redis for k/v lookup as part of a single query fronted by postgres?
- atwebb 7y agoI haven't used FDW directly but I would suspect the performance would largely be related to how you can get pushdown and native usage within the source system. Combining data almost must be done on the master node.
