Import / Export of resources between projects

info

This feature is available from v12.0.0 of Mia-Platform Console (you can enable it in the Feature Preview of your Project Settings).

The Import / Export feature allows Fast Data users to export resources from a specific project and import them inside another one.
This feature makes it easier to access resources from other projects without having to recreate them on each environment.

The following resources can be imported / exported:

  • Custom cast functions (assigned to a Projection field)
  • ER schemas
  • Single Views
  • Systems of Record (with all or some of their Projections)
caution

Some Fast Data resources, such as Projections, can be imported as a reference only in Projects that are using the Single View Trigger Generator architecture. Please check your services before importing the resources.

The feature can be accessed by clicking on the Import / Export button, placed on the top right bar of the Systems of Record and Single Views pages. After clicking on the button, it will be possible to open the Import or Export modals.

Import / Export from Systems page

It is also possible to import resources by clicking on the Import button displayed on the placeholder screen shown when no Systems of Record or Single Views have been created inside the configuration.

Export​

After clicking on the Export button, a modal will display exportable Fast Data resources in their respective tabs, if present.

From each tab it will be possible to select and deselect the resources to be exported.

Export modal

When clicking on the Export button on the modal footer, a fast-data-export-{export-timestamp}.json file will be downloaded, containing the selected resources in JSON format and some information about the current project, branch and exporting time. This metadata will be useful when importing resources inside another project.

When exporting one or more ER schemas, a check will be performed on the potential related resources (such as Projections and Single Views) to make sure they are exported as well. If not already included in the export selection, another screen will be opened to display all of the ER schemas dependencies. After the Confirm and export button is clicked, these dependencies will be included inside the exported file.

Export modal with dependencies

If a custom cast function is assigned to one or more Projection fields and the Projection is exported, the cast function will be exported as well.

Import​

After clicking on the Import button, it will be possible to upload a .json file containing exported data inside a modal.

The imported file should follow the format of files downloaded using the Export feature.

If the file is valid, information about the source project, branch and exporting time will be displayed.

When clicking on the Next button, all of the Fast Data resources contained inside the imported file will be displayed in their respective tabs. It will be possible to select and deselect resources before completing the import process by clicking on the Confirm and import button.

Import modal with resources selection

Fast Data resources can be imported in two ways:

1) as a reference: the resources will be referenced inside the current project configuration and displayed in read-only mode. It will be possible to access their data but the resources will not be editable. A Reference label will be added to their name inside the Fast Data section: when hovering it, a popover will display information about the exporting source project, branch and time.

2) as a resource: the resources will be copied inside the current project configuration and displayed as if they were created directly inside the current project. It will be possible to access and edit their data.

In both cases, an error message will be displayed if some of the imported resources have the same name of resources or references already existing inside the project current configuration. An edit button will be then displayed to allow the renaming of these resources, unless the resources, in turn, have already been exported from external projects.

Import modal with error

It will be possible to update references only by importing resources with the same name and from the same source project. In this case, the Reference update label will be displayed alongside each updated resource and its content will be overwritten inside the configuration.

caution

Resources imported by reference are not automatically synced between projects. In order to update them, it will be necessary to manually export them from the source project and import them again inside the destination project.

caution

In both cases, microservices associated to each resource (such as Real-Time Updaters and their Message Formats, Single View Creators or Single View Trigger Generators) will NOT be imported. Please make sure these services have been created before deploying your configuration.
