feat: modernization part 2 #1748

feywind · 2025-12-11T21:57:54Z

This is a follow-up for these two PRs:

This takes care of some missing pieces that were discovered by further discussion:

GcRuleBuilder is a more TypeScript-heavy way to validate ModifyColumnFamilies garbage collection rules, with type checking taking care of a lot of the constraints, and some minimal runtime checking for JavaScript users.
Rather than raw GAPIC, the focus has shifted to selective GAPIC subclasses that can augment them. This is specifically done to assist with RestoreTable and waiting for table consistency.
Data plane samples have been removed, as we don't want to encourage users to use them.
Generated samples and tests have been auto-edited to use the selective GAPIC classes.
Manual sample snippets have been updated to reflect the expected admin access and GcRuleBuilder usage.

There is still a CI issue that will need to be corrected before this can be merged. I don't think it's the result of this change, but I also don't want to chance it.

The CI is really not cooperating here (timeouts, quota errors, etc) but the code itself should be okay to review.

mutianf

Where did all the data API examples go?

mutianf · 2026-01-05T18:26:01Z

samples/generated/admin/v2/bigtable_table_admin.check_consistency.js


  // Imports the Admin library
-  const {BigtableTableAdminClient} = require('@google-cloud/bigtable').admin.v2;
+  const {TableAdminClient} = require('@google-cloud/bigtable').admin;


should this sample reflect the new CUJ?

await tableAdmin.waitForConsistency('tablename');

or

const [token] = await tableAdmin.generateConsistencyToken({ name: 'tablename', }); // overload/etc, may be a separate method await tableAdmin.waitForConsistency(token);

mutianf · 2026-01-05T18:27:47Z

samples/generated/admin/v2/bigtable_table_admin.generate_consistency_token.js


  // Instantiates a client
-  const adminClient = new BigtableTableAdminClient();
+  const adminClient = new TableAdminClient();


same here, should this be merged with check_consistency to reflect the newer way of generate consistency token and wait for table to be consistent?

mutianf · 2026-01-05T18:30:43Z

samples/generated/admin/v2/bigtable_table_admin.restore_table.js


  // Instantiates a client
-  const adminClient = new BigtableTableAdminClient();
+  const adminClient = new TableAdminClient();


This also doesn't reflect the new CUJ

Important point for all of these under generated/, they are just GAPIC generated samples that got moved around and programmatically modified in owlbot.py to use the selective GAPIC class names and such. The admin ones we want to keep (although we could also just delete the restore table and consistency token ones if desired). The data plane ones, I talked with @igorbernstein2 about, we're just going to drop those to discourage their use vs the veneer.

I'm happy to do as you all like on these, though, I don't feel strongly about it.

-      versions: 1,

-  };
+  const updatedMetadata = GcRuleBuilder.rule({


I wonder if this example can be added to the modifyColumnFamilies example as well?

I might've missed one, but I agree.

Actually I'm not sure I see where it's missing - can you paste a link?

I'm not sure if I understand this paragraph. In the example I see const adminClient = new TableAdminClient();. Is this section explaining how to get the TableAdminClient from a gapic generated client?

The opposite, actually. It's explaining how to get a GAPIC client from the veneer object that users are used to using already. The GAPIC clients can be created without any extra parameters, so that's why the generated samples are like that, but if the user needs auth configuration or whatnot, it's simpler to get it from the Bigtable object than to rebuild it.

+  async checkOptimizeRestoredTableProgress(


Do we have this in the example?

Also this API looks a bit different from the doc? https://docs.google.com/document/d/14aOXOpEbwpYJe7-p6E-PUgoy0vn4AKI7zP0Man0prLo/edit?tab=t.0
