FDBKeeper Experimental Evaluation

---

---

This is the experimental evaluation code repo for the paper "Enabling Scalable Coordination Services for Metadata Management using Distributed Key-Value Databases: A Design Space Exploration".

Some scripts for setting up a benchmark environment for FDBKeeper.

Usage

Setup Local Depends

pipenv install

Setup Hosts

1. Prepare at least 1 host for client, at least 1 host for foundationdb or zookeeper service.

2. Server requirements

   1. Ubuntu 22.04 is recommended
   2. Mount ext4 fs on /var/lib/keeper-bench with options: defaults,noatime,discard
   3. Setup prometheus node exporter with textfile collector for /var/lib/node_exporter
   4. Setup prometheus pushgateway for keeper-bench.

3. Create ansible inventory file: hosts.yml. Put hosts in clients and servers groups. Here is a simple example:

   all:
   children:
      clients:
         hosts:
         c1:
            ansible_host: 1.2.3.4
         c2:
      servers:
         hosts:
         s1:
            fdb_coordinator: true
            fdb_procs: [transaction, storage]
         s2:
   vars:
      keeper_bench_path: /local/path/to/keeper-bench
      fdb_init_command: configure new triple ssd

Setup Prometheus and Grafana

We use prometheus and grafana to collecting metrics. You can use docker compose to deploy a simple prometheus:

# Create file sd configs if you setup hosts without `setup-ecnu-cloud` playbook.
touch docker/prom_file_sd.yml

# Up docker compose services
docker compose up -d

# Grafana is available on 0.0.0.0:9033

Open 127.0.0.1:9033 and setup data source and dashboard manually. Here is a dashboad example

Deploy Benchmark Clients and Services
