pd-tso-bench

pd-tso-bench is a tool to benchmark GetTS performance.

Build

1. Go Version 1.21 or later
2. In the root directory of the PD project, use the make command to compile and generate bin/pd-tso-bench

Usage

This section describes how to benchmark the GetTS performance.

Flags description

-c int
  concurrency (default 1000)
-cacert string
  path of file that contains list of trusted SSL CAs
-cert string
  path of file that contains X509 certificate in PEM format
-client int
  the number of pd clients involved in each benchmark (default 1)
-count int
  the count number that the test will run (default 1)
-dc string
  which dc-location this bench will request (default "global")
-duration duration
  how many seconds the test will last (default 1m0s)
-interval duration
  interval to output the statistics (default 1s)
-key string
  path of file that contains X509 key in PEM format
-pd string
  pd address (default "127.0.0.1:2379")
-v output statistics info every interval and output metrics info at the end

Benchmark the GetTS performance:

    ./pd-tso-bench -v -duration 5s

It will print some benchmark results like:

Start benchmark #0, duration: 5s
Create 3 client(s) for benchmark
