This page shows you how to reproduce CockroachDB's TPC-C performance benchmarking results on commodity AWS hardware. Across all scales, CockroachDB can process tpmC (new order transactions per minute) at near maximum efficiency. Start by choosing the scale you're interested in:
|Workload||Cluster size||Warehouses||Data size|
|Local||3 nodes on your laptop||10||2 GB|
|Small||3 nodes on
|Medium||15 nodes on
|Large||81 nodes on
Before you begin
Review TPC-C concepts
TPC-C provides the most realistic and objective measure for OLTP performance at various scale factors. Before you get started, consider reviewing what TPC-C is and how it is measured.
Step 1. Set up the environment
Create 4 VM instances, 3 for CockroachDB nodes and 1 for the TPC-C workload.
- Create all instances in the same region and the same security group.
- Use the
- Use local SSD instance store volumes. Local SSDs are low latency disks attached to each VM, which maximizes performance. This configuration best resembles what a bare metal deployment would look like, with machines directly connected to one physical disk each. We do not recommend using network-attached block storage.
Note the internal IP address of each instance. You'll need these addresses when starting the CockroachDB nodes.
This configuration is intended for performance benchmarking only. For production deployments, there are other important considerations, such as security, load balancing, and data location techniques to minimize network latency. For more details, see the Production Checklist.
Configure your network
CockroachDB requires TCP communication on two ports:
26257for inter-node communication (i.e., working as a cluster) and for the TPC-C workload to connect to nodes
8080for exposing your DB Console
Create inbound rules for your security group:
Inter-node and TPCC-to-node communication
|Type||Custom TCP Rule|
|Source||The name of your security group (e.g., sg-07ab277a)|
|Type||Custom TCP Rule|
|Source||Your network's IP ranges|
Step 2. Start CockroachDB
--insecure flag used in this tutorial is intended for non-production testing only. To run CockroachDB in production, use a secure cluster instead.
SSH to the first VM where you want to run a CockroachDB node.
Download the CockroachDB archive for Linux, extract the binary, and copy it into the
$ wget -qO- https://binaries.cockroachdb.com/cockroach-v20.2.3.linux-amd64.tgz \ | tar xvzcopy
$ cp -i cockroach-v20.2.3.linux-amd64/cockroach /usr/local/bin/
If you get a permissions error, prefix the command with
$ cockroach start \ --insecure \ --advertise-addr=<node1 internal address> \ --join=<node1 internal address>,<node2 internal address>,<node3 internal address> \ --cache=.25 \ --background
Repeat steps 1 - 3 for the other 2 VMs for CockroachDB nodes. Each time, be sure to adjust the
On any of the VMs with the
cockroachbinary, run the one-time
cockroach initcommand to join the first nodes into a cluster:copy
$ cockroach init --insecure --host=<address of any node>
Step 3. Import the TPC-C dataset
CockroachDB offers a pre-built
workload binary for Linux that includes the TPC-C benchmark. You'll need to put this binary on the VM for importing the dataset and running TPC-C.
SSH to the VM where you want to run TPC-C.
workloadbinary for Linux and make it executable:copy
$ wget https://edge-binaries.cockroachdb.com/cockroach/workload.LATEST -O workload; chmod 755 workload
Import the TPC-C dataset:copy
$ ./workload fixtures import tpcc \ --warehouses 2500 \ "postgres://root@<address of any CockroachDB node>:26257?sslmode=disable"
This will load 200 GB of data for 2500 "warehouses". This can take a while to complete.
You can monitor progress on the Jobs screen of the DB Console. Open the DB Console by pointing a browser to the address in the
adminfield in the standard output of any node on startup.
Step 4. Run the benchmark
Still on the VM with the
workloadbinary, create an
addrsfile containing connection strings to the 3 CockroachDB nodes:
postgres://root@<node 1 internal address>:26257?sslmode=disable postgres://root@<node 2 internal address>:26257?sslmode=disable postgres://root@<node 3 internal address>:26257?sslmode=disable
Run TPC-C for 30 minutes:copy
$ ./workload run tpcc \ --warehouses 2500 \ --ramp 1m \ --duration 30m \ $(cat addrs)
Step 5. Interpret the results
workload has finished running, you will see a final result similar to the following. The efficiency and latency can be combined to determine whether this was a passing run. You should expect to see an efficiency number above 95%, well above the required minimum of 85%, and p95 latencies well below the required maximum of 10 seconds.
_elapsed_______tpmC____efc__avg(ms)__p50(ms)__p90(ms)__p95(ms)__p99(ms)_pMax(ms) 1800.0s 31064.6 96.6% 107.4 88.1 243.3 302.0 402.7 973.1
CockroachDB works well on commodity hardware in public cloud, private cloud, on-prem, and hybrid environments. For hardware recommendations, see our Production Checklist.
Also note that CockroachDB creates a yearly cloud report focused on evaluating hardware performance. For more information, see the 2020 Cloud Report.
