Goal

The goal of this benchmark is to get an idea of the performance of YugabyteDB using a key-value workload.

Recommended configuration

Cluster configuration

For this benchmark, we will setup a 3-node cluster with a replication factor of 3.

Machine configuration

  • Amazon Web Services

    • Instance type: i3.4xlarge
    • Disks: 2 x 1.9 TB NVMe SSDs (comes pre-configured with the instance)
  • Google Cloud Platform

    • Instance type: n1-standard-16
    • Disks: 2 x 375 GB SSDs
  • On-Premises Datacenter

    • Instance: 16 CPU cores
    • Disk size: 1 x 200 GB SSD (minimum)
    • RAM size: 30 GB (minimum)

Benchmark tool

We will use the yb-sample-apps.jar tool to perform this benchmark. You can get it from this GitHub repository as shown below.

$ wget https://github.com/yugabyte/yb-sample-apps/releases/download/v1.2.0/yb-sample-apps.jar?raw=true -O yb-sample-apps.jar

You would need to install java in order to run this tool. Also export the environment variable $ENDPOINTS containing the IP addresses (plus port) for the nodes of the cluster.

ENDPOINTS="X.X.X.X:9042,X.X.X.X:9042,X.X.X.X:9042"

Write-heavy KV workload

Run the key-value workload with higher number of write threads (representing write-heavy workload).

Load 1B keys of 256 bytes each across 256 writer threads

$ java -jar ./yb-sample-apps.jar  \
      --workload CassandraKeyValue   \
      --nodes $ENDPOINTS             \
      --nouuid                       \
      --value_size 256               \
      --num_threads_read 0           \
      --num_threads_write  256       \
      --num_unique_keys 1000000000

Expected results

Name Observation
Write Ops/sec ~90k
Read Latency ~2.5-3.0 ms/op
CPU (User + Sys) 60%

Read-heavy KV workload

Run the key-value workload with higher number of read threads (representing read-heavy workload).

Load 1M keys of 256 bytes and access them with 256 reader threads

$ java -jar ./yb-sample-apps.jar  \
      --workload CassandraKeyValue   \
      --nodes $ENDPOINTS             \
      --nouuid                       \
      --value_size 256               \
      --num_threads_read 256         \
      --num_threads_write 0          \
      --num_unique_keys 1000000

Expected results

Name Observation
(Read) Ops/sec ~150k
(Read) Latency ~1.66 ms/op
CPU (User + Sys) 60%

Batch write-heavy KV workload

Run the key-value workload in batch mode and higher number of write threads (representing batched, write-heavy workload).

Load 1B keys of 256 bytes each across 64 writer threads in batches of 25 each

$ java -jar ./yb-sample-apps.jar      \
      --workload CassandraBatchKeyValue  \
      --nodes $ENDPOINTS                 \
      --nouuid                           \
      --batch_size 25                    \
      --value_size 256                   \
      --num_threads_read 0               \
      --num_threads_write 64             \
      --num_unique_keys 1000000000

Expected results

Name Observation
(Batch Write) Ops/sec ~140k
(Batch Write) Latency ~9.0 ms/op
CPU (User + Sys) 80%
