Sample golang app with workers and clients to generate load.
This example assumes that you have a temporal cloud namespace configured and have local client certificate files for your namespace. It also assumes the usage of direnv.
The values are passed into the demo app using environment variables, example direnv .envrc file is included in the repo:
# direnv .envrc
# Temporal Cloud connection
# region: us-east-1
export TEMPORAL_HOST_URL="myns.abcdf.tmprl.cloud:7233"
export TEMPORAL_NAMESPACE="myns.abcdf"
# tclient-myns client cert
export TEMPORAL_TLS_CERT="/Users/myuser/.temporal/tclient-myns.pem"
export TEMPORAL_TLS_KEY="/Users/myuser/.temporal/tclient-myns.key"
# Optional: path to root server CA cert
export TEMPORAL_SERVER_ROOT_CA_CERT=
# Optional: Server name to use for verifying the server's certificate
export TEMPORAL_SERVER_NAME=
export TEMPORAL_INSECURE_SKIP_VERIFY=false
# App temporal taskqueue name for moneytransfer
export TRANSFER_MONEY_TASK_QUEUE="go-moneytransfer"
# timer for transfer table to be checked (seconds)
export CHECK_TRANSFER_TASKQUEUE_TIMER=20
# payload data encryption
export ENCRYPT_PAYLOAD=false
export DATACONVERTER_ENCRYPTION_KEY_ID=mysecretkey
# Set to enable debug logger logging
export LOG_LEVEL=debug
# local mysql backend db connection
export MYSQL_HOST=localhost
export MYSQL_DATABASE=dataentry
export MYSQL_USER=mysqluser
export MYSQL_PASSWORD=mysqlpw
It was valuable to me to decrease the limits of my namespace below the defaults, to generate rate-limiting throughput without overloading my testing machine (i7-13700H 2.40 GHz/32MB RAM) or incur unnecessary spend on infrastructure. I went with 40 APS/160 RPS.
- Start workers
go run accumulator/worker/main.go
I recommend starting several, I went with 6.
- Start workflows
go run accumulator/starter/main.go
I recommend starting several, I ramped up from 2 up to 7 to get above 160 RPS.
- Start Querier
go run accumulator/query/main.go
I recommend 2.
- Monitor your namespace's metrics, observe rate limiting.
