My background is in running a mid-sized e-commerce operation, about 200 GB of transactional data growing 15% a year, nothing insane. We currently dump everything into PostgreSQL and run our reporting queries against a read replica. It works, sort of. Aggregations over 6 months of order data take 30 seconds, which management tolerates but constantly complains about. I’ve looked at column-store options, tried ClickHouse on a single node, got it to run but the SQL compatibility gap was a nightmare for the BI team. Also looked at DuckDB for local analytics, which is fast but doesn’t solve the multi-user, always-on requirement. Everything I read about Snowflake or BigQuery comes with a cost horror story from someone who accidentally left a join running over a poorly partitioned table and got a bill that made them question their career choices.

What I’ve actually tried and failed at: setting up TimescaleDB, which solved time-series performance but added operational complexity that broke our backup scripts. Then I spent a weekend with Apache Druid, hit the learning curve hard, and the real-time ingestion pipeline kept crashing because our data isn’t uniformly structured. Also evaluated MotherDuck, which is basically managed DuckDB, but the pricing model for concurrent queries felt opaque and I don’t trust a relatively new company with our only analytics store.

So here’s my real question: is there a database that actually handles sub-second analytics on a few hundred GB of data, supports full SQL, doesn’t require a dedicated DBA, and whose cost doesn’t spike unpredictably when someone runs a slightly inefficient query? I’m not looking for a magic bullet or a hype train. I want a concrete comparison of how PostgreSQL with columnar extensions stacks up against something like SingleStore or a self-hosted ClickHouse cluster, specifically from people who run this in production without a team of infrastructure engineers. Give me the real trade-offs, not the Gartner quadrant.]]>
