bigquery-export: Add `document.id` to BigQuery tables

[REQUIRED] Step 2: Extension name

This feature request is for extension: firestore-bigquery-export

What feature would you like to see?

For this feature to be useful to me, I really need the firestore document’s id exposed as a single field in the generated tables. Currently, the fully qualified document_name is provided, but this includes a bunch of additional prefixes that makes it really difficult/cumbersome to join across tables.

How would you use it?

I want to use the big query tables to power DataStudio as well as for running one-off queries to better understand my app’s usage.

I often store data semi-normalized using document identifiers, such as memberId (which is like a userId), and then need to join to the memebers collection, using memberId as the join key.

Currently, I would have to concact a string together to join on document_name in this format

projects/XX-project-nameXX/databases/(default)/documents/members/<my member document id>

That would be my recommendation 😄 .

@mustafaekim May I ask what version of the firestore-bigquery-export extension you’re using? You should be able to see it in your Firebase console dashboard in the extension’s tab.
