falkordb Profile
1. Flamegraphs with samply
For finding performance bottlenecks in query execution (full reference:
docs/profiling.md):
cargo install samply # one-time
# [profile.release] has `debug` commented out in Cargo.toml, so a plain
# --release build has no line info. Add debuginfo for readable flamegraphs:
RUSTFLAGS="-C debuginfo=2" cargo build --release
# record redis-server with the module loaded, run your query/workload
# against it, then stop the server
samply record redis-server --loadmodule ./target/release/libfalkordb.dylib
On stop, samply opens the Firefox Profiler UI in your browser. Use
libfalkordb.so on Linux.
2. Benchmark suite
CI runs the A/B FalkorDB-vs-FalkorDB benchmark pipeline
(.github/workflows/_benchmark.yml, driven by the FalkorDB/benchmark
tool) and publishes the trend to
https://falkordb.github.io/falkordb-rs-next-gen/benchmark/ — compare
against that history when checking for a regression.
