A Postgres wire protocol aware mirroring proxy.

Frenzy is an experimental Postgres mirroring proxy that allows mirroring production traffic to shadow instances. Frenzy allows you to service production traffic from a primary while measuring one or more mirror shadow instances.

Frenzy takes 1 primary connection string that will be used to respond to production requests and multiple mirror connection strings that will receive the duplicated traffic from the primary.

To compile the bin/frenzy binary run the following.

make

Provide 1 primary Postgres connection string and one or many mirror Postgres connection strings.

./bin/frenzy --listen :5432 \
    --primary postgresql://postgres:password@localhost:5441/postgres \
    --mirror postgresql://postgres:password@localhost:5442/postgres

Right now I am testing with a simple hello world query.

PGPASSWORD=password psql -U postgres -h localhost -p 5432 -c "SELECT version();"

Surprisingly I've seen more complicated queries work already! \l in the psql console also dispatches a more complicated query that seems to work!
