chihiro's Introduction

Chihiro

Prisma benchmarking tool.

Usage

The provided queries are supposed to run against a Chinook database. The provided database setups should contain the needed data.

First start the database:

> docker-compose -f docker/docker-compose.postgres.yml up -d

After the database is up and running, start an instance of prisma pointing to the database, preferably in release mode.

> RUST_LOG_FORMAT=devel RUST_LOG=info PRISMA_DML_PATH=datamodel_postgres.prisma prisma

Edit a test file, describing where to find the tests and how to run them:

identifier = "master_test_run"
duration_per_test = 240 # seconds
elastic_endpoint = "https://16a31d8b2f8042df82b75bd7759edb00.eu-central-1.aws.cloud.es.io:9243/"

[rates] # test runs, integer is requests per second
very_slow = [25, 50, 75, 100, 125, 150, 175, 200, 225, 250]
slow = [25, 50, 75, 100, 125, 150, 175, 200, 225, 250]
medium = [100, 200, 300, 400, 500, 600, 700, 800, 900, 1000, 2000]
fast = [200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 4000]
very_fast = [200, 400, 600, 800, 1000, 1200, 1400, 1600, 1800, 2000, 4000]

[[test_run]]
path = "./queries/" # runs all queries from all subdirs
[test_run.variables.artist_id]
minimum = 1 # we randomise every $artist_id in queries, starting from this
maximum = 275 # ... and ending to this
[test_run.variables.track_id]
minimum = 1 # randomise $track_id in queries, starting from this
maximum = 3503 # ... and ending to this

Compile chihiro in release mode (important) and run the tests against the Prisma server.

To be able to store anything to the elasticsearch database, you need the login credentials set into ELASTIC_USER and ELASTIC_PW env vars.
