Using MigratePostRowSave Event to append data to a migrated item

The migrate system in Drupal 8 is very powerful. In very few lines of code, you can hook into various data sources, process and import data into Drupal.

Break down datasets to avoid out of memory errors in migrations

Having worked on a project this year that makes extensive use of Migrate in Drupal 8, there are some considerations to have when running them on a remote system.

In our case, we have a half dozen ongoing migrations that run every night. These are JSON files that are delivered from a remote system every night. The processing to generate output on the remote system is too time intensive, so we are not fetching via the HTTP capability of Migrate Plus.

Creating a custom process plugin for Drupal 8 Migrate

I've done a lot of migrations in Drupal 5, 6, and 7. Migrating into 5 and 6 was pretty rough. Version 5 basically required raw script power and chunked looping. 6 did as well. By the time I had to do migrations for projects again, I was well into developing projects in Drupal 7.

Using the Migrate Framework with a remote database on Pantheon

Using the Migrate Framework with a remote database on Pantheon

If you host your Drupal site on the Pantheon platform, you may already know that you do not need to include a settings.php file because they provide the connection information for you automatically. However, you can provide one if you are setting up database connections. What was unclear, at least to me, is that you can only define connections for local development. Connections are otherwise ignored on the Pantheon environment, I assume for security reasons (since the user/pass/host would be out in the open) and probably other technical reasons I am unaware of.
