Which property should I set to save the last imported time in the migration map (SQL)?

I've seen that adding:

  track_changes: true


The hash is been calculated but no idea how to set the calculation of the time.

You have to set setTrackLastImported to TRUE.

What I've done is create a new source plugin that extends the source plugin that I was using and set to true the last imported property.

 * Source plugin that extends "url" source plugin and saves the last imported
 * date.
 * @MigrateSource(
 *   id = "url_last_import"
 * )
class UrlLastImport extends Url {

public function __construct(array $configuration, $plugin_id, $plugin_definition, MigrationInterface $migration) {
    parent::__construct($configuration, $plugin_id, $plugin_definition, $migration);

I don't know if it's the best solution, but it works.


The last import date for a migration is stored in the key_value store.

See Drupal\migrate_tools\Controller\MigrationListBuilder.php for an example on how to get the timestamp of the last import for a given migration:

  $migrate_last_imported_store = \Drupal::keyValue('migrate_last_imported');
  $last_imported = $migrate_last_imported_store->get($migration->id(), FALSE);

Next to the last imported timestamp it's also possible to get a timestamp for each row (with setTrackLastImported(), see Drupal\migrate\Plugin\migrate\id_map\Sql).

  • The value retrieved is in milliseconds so make sure you divide by 1000. Example can be found in modules/contrib/migrate_tools/src/Controller/MigrationListBuilder.php. Apr 24, 2019 at 12:36
