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.
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!
