State

The State Adapter is responsible for database persistence, caching, and storage on the Devprime platform. The Adapter State can be customized with a variety of options, including MongoDB, SQL Server, MySQL, PostgreSQL, ElasticSearch, Oracle, Redis, and other storage parameters such as Azure Store, AWS S3, Google Cloud Storage, and many others.

  "DevPrime_State": [
    {
      "enable": "true",
      "alias": "State1",
      "type": "db",
      "dbtype": "mongodb",
      "connection": "mongodb://mongoadmin:LltF8Nx*yo@localhost:27017",

      "isssl": "true",
      "numberofattempts": "4",
      "durationofbreak": "45"
    }
  ],

In the table below, you can see a summary of the main configuration parameters.

State	—
enable	Enable the State adapter (True/False)
alias	Defines a unique name to identify the service
type	Sets the State type (DB
dbtype	Defines the database service (MongoDB
dbname	Database Name / Collection
connection	Defines the configuration of the access connection
timeout	Sets the default timeout to fail
retry	Configure the number of retries
isssl	Enables a secure connection (True/False)
numberofattempts	Sets the number of attempts
durationofbreak	Set the duration of the Circuit-Break

The State Adapter supports multiple data persistences

The Devprime platform’s State Adapter supports more than one State service simultaneously, to cater to specific scenarios where it is necessary to have both MongoDB and Redis in the same microservice and one Storage.

In this type of implementation, it is necessary that each service has its own Alias.

To export the configurations as an environment variable and use in Kubernetes, run the command in the Devprime CLI:
dp export kubernetes
