Test Objective

This document aims to measure the number of measurement points written per second when time series data is continuously written to InfluxDB under specific configurations. By systematically adjusting key parameters, the test measures and optimizes the write performance of InfluxDB, providing a performance benchmark reference for deployment in production environments.

Key Test Parameters

Parameter
Description
Tuning Suggestion
Worker (Concurrency)
Number of clients that simultaneously initiate write requests to the database
Start from a lower value (such as 4–8)
Gradually increase the value until performance no longer improves.
Use it to test the system concurrent processing capability.
Batch (Batch Size)
Number of data rows written in each batch, with a default of 10,000
Impact of data volume on a single write operation:
If the volume is too small, the network overhead will be increased.
If the volume is too large, the memory pressure will be increased.

Test Configuration Example

cat data/influx-data-cpu-10000-30day.gz | gunzip | ./tsbs_load_influx \\
    --urls=http://XX.XX.XX.XX:8086 \\  # The InfluxDB cluster address.
    --db-name=test \\                  # The target database name.
    --workers=10 \\                    # Set the number of concurrent workers to 10.
    --user=ctsdbi-mjhiaefp \\          # The username for authentication.
    --password=Xstor@2025 \\           # The password for authentication.
    --do-create-db=false              # Assume that a database already exists and do not create a database.
