Pipeline resource optimization
Pipeline resource optimization takes the resource usage information from previous workflow runs to optimize subsequent runs.
The pipeline resource optimization service requires a separate database schema to store its internal data, but also requires access to the Seqera schema. The Seqera and optimization service schemas can coexist on the same database instance.
Docker Compose deployment
Docker Compose makes use of a separate container to set up the pipeline resource optimization service during initialization. Configuration steps differ for new and existing deployments.
New installation
To use the pipeline resource optimization service in a new Docker Compose installation of Seqera Enterprise, use the following steps:
- 
To run the service from a custom URL, declare the URL with the GROUNDSWELL_SERVER_URLenvironment variable intower.env. A non-zero value for this environment variable activates the optimization service automatically, soTOWER_ENABLE_GROUNDSWELLdoes not need to be set when you declare a custom URL.
- 
Set the TOWER_ENABLE_GROUNDSWELLenvironment variable intower.envtotrue. This enables the service at the default service URLhttp://groundswell:8090.
- 
In your docker-compose.yml file, uncomment the groundswellsection at the bottom.- To create a schema for the optimization service on the same local MySQL container, uncomment the init.sqlscript in thevolumessection.
 
- To create a schema for the optimization service on the same local MySQL container, uncomment the 
- 
Download the init.sql file. Store this file in the mount path of your docker-compose.ymlfile, else update thesource: ./init.sqlline in yourdocker-compose.ymlwith the file path.
- 
When the pipeline resource optimization service is active, pipelines that can be optimized display a lightbulb icon in your Launchpad. Any pipeline with at least one successful run can be optimized. 
Existing installation
To use the pipeline resource optimization service in an existing Docker Compose installation of Seqera Enterprise, use the following steps:
- 
To run the service from a custom URL, declare the URL with the GROUNDSWELL_SERVER_URLenvironment variable. A non-zero value for this environment variable activates the optimization service automatically, soTOWER_ENABLE_GROUNDSWELLdoes not need to be set when you declare a custom URL.
- 
Set the TOWER_ENABLE_GROUNDSWELLenvironment variable totrue. This enables the service at the default service URLhttp://groundswell:8090.
- 
In your docker-compose.yml file, uncomment the groundswellsection at the bottom. If you use adocker-compose.ymlfile older than version 23.3, download a newer version of the file to extract thegroundswellsection.
- 
Log in to your database server and run the following commands: CREATE DATABASE IF NOT EXISTS `swell`;
 CREATE USER 'swell'@'%' IDENTIFIED BY 'swell';
 GRANT ALL PRIVILEGES ON *.* TO 'swell'@'%';
 FLUSH PRIVILEGES;
- 
If you use Amazon RDS or other managed database services, run the following commands in your database instance: CREATE DATABASE IF NOT EXISTS `swell`;
 CREATE USER 'swell'@'%' IDENTIFIED BY 'swell';
 GRANT ALL PRIVILEGES ON `%`.* TO 'swell'@'%';
 FLUSH PRIVILEGES;
- 
Download the groundswell.env file. Store this file in the mount path of your docker-compose.ymlfile. Update theTOWER_DB_URLandSWELL_DB_URLvalues:# Uncomment for container DB instances
 # TOWER_DB_URL=mysql://db:3306/tower
 # SWELL_DB_URL=mysql://db:3306/swell
 # Uncomment for managed DB instances (Example URL shows an Amazon RDS instance URL)
 # TOWER_DB_URL=mysql://db1.abcdefghijkl.us-east-1.rds.amazonaws.com:3306/tower
 # SWELL_DB_URL=mysql://db1.abcdefghijkl.us-east-1.rds.amazonaws.com:3306/swell
- 
When the pipeline resource optimization service is active, pipelines that can be optimized display a lightbulb icon in your Launchpad. Any pipeline with at least one successful run can be optimized. 
Kubernetes deployment
Kubernetes deployments use an initContainer that runs during pod initialization to set up the pipeline resource optimization service. To use the service in new or existing Kubernetes installations of Seqera Enterprise, do the following:
- 
Download the groundswell manifest: ---

To run the service from a custom URL, declare the URL with the GROUNDSWELL_SERVER_URLenvironment variable in theconfigmap.ymlfile that you downloaded for your Platform installation. A non-zero value for this environment variable activates the optimization service automatically, soTOWER_ENABLE_GROUNDSWELLdoes not need to be set when you declare a custom URL.
- 
Define a set of credentials for the optimization database. This can be the same database used for Seqera, but in a different schema. 
- 
Log in to your database server and run the following commands: - 
If you use Amazon RDS or other managed database services, run the following commands in your database instance: CREATE DATABASE IF NOT EXISTS `swell`;
 CREATE USER 'swell'@'%' IDENTIFIED BY 'swell';
 GRANT ALL PRIVILEGES ON `%`.* TO 'swell'@'%';
 FLUSH PRIVILEGES;
- 
If you do not use a managed database service, run the following commands in your database instance: CREATE DATABASE IF NOT EXISTS `swell`;
 CREATE USER 'swell'@'%' IDENTIFIED BY 'swell';
 GRANT ALL PRIVILEGES ON *.* TO 'swell'@'%';
 FLUSH PRIVILEGES;
 
- 
The initContainers process will wait until both the Seqera and pipeline resource optimization service databases are ready before starting the migration in the Seqera database and finally starting the optimization container.
When the pipeline resource optimization service is active, pipelines that can be optimized display a lightbulb icon in your Launchpad. Any pipeline with at least one successful run can be optimized.
