Go1.14+.
By default pegasus-go-client logs to "./pegasus.log" on where your application runs. You can customize the logging rules as follows:
// customize where the pegasus-go-client's logs reside.
pegalog.SetLogger(pegalog.NewLogrusLogger(&pegalog.LogrusConfig{
// rotation rules
MaxSize: 500, // megabytes
MaxAge: 5, // days
MaxBackups: 100,
// log files location
Filename: "/home/work/myapp/log/pegasus.log",
}))
To print the logs on screen:
pegalog.SetLogger(pegalog.StderrLogger)
We highly recommend you to enable client logging for debugging purpose. If you want support for other log destinations or log formats, please submit an issue for that.
import (
"context"
"github.com/apache/incubator-pegasus/go-client/pegasus"
)
cfg := Config{
MetaServers: []string{"0.0.0.0:34601", "0.0.0.0:34602", "0.0.0.0:34603"},
}
client := NewClient(cfg)
defer client.Close()
tb, err := client.OpenTable(context.Background(), "temp")
err = tb.Set(context.Background(), []byte("h1"), []byte("s1"), []byte("v1"))

Before using pegasus-go-client, it's recommended to configure GOBACKTRACE so as to generate coredump while program unexpectedly corrupts.
ulimit -c unlimited
export GOBACTRACE=crash
