A 17× perf gap between pg-raggraph and Apache AGE turned out to be 5 lines of glue code in the bakeoff adapter, not an architectural problem. The fix, the four library-side wins still on the floor, and the three architectural directions ahead — pg_net sidecar, pgrx Rust extension, hybrid embedding tiers.
Three corpora, three different winners, none of them the chunker the README recommended. Why nobody can tell you in advance which chunker to use, and the 30-minute primitive that does the work for you.
Build a capacity benchmark from real captured traffic, sweep 1x → 50x, and drive PostgreSQL into saturation on purpose so you find the knee before production does.
From git clone to capturing a real PostgreSQL workload and replaying it against a test target — end-to-end on your laptop, with every command actually run.
Scripts to test and benchmark JSON functionality across MySQL, PostgreSQL, and MongoDB — and generate simulated load.
Capture, replay, and compare PostgreSQL workloads. Validate config changes, migrations, and capacity plans with confidence.
