Add support for REST catalog in Iceberg connector by kiersten-stokes · Pull Request #22417 · prestodb/presto

kiersten-stokes · 2024-04-03T23:16:26Z

Description

This PR is two commits:

one that adds support for REST, which necessitates updating com.fasterxml.jackson.core:jackson-core and :jackson-databind to be >2.11 in the root pom
one that re-factors the Iceberg catalog implementation to be more modular (contains the bulk of the code changes)

Motivation and Context

Closes #20422

Impact

Adds support for using the Iceberg REST catalog

Test Plan

Tests have been added that spin up a testing HTTP server to create an Iceberg REST catalog with JDBC backing. Currently, three of the distributed smoke tests fail when using this set up due to a bug in Iceberg that I intend to follow up on

Thanks for the documentation! Just two nits.

ZacBlanco

Changes look good overall except that I think I disagree with leaving the refactor until later on IcebergResourceFactory. Might even be better to have this PR with 2 commits: one for the refactor and one for the REST catalog?

How were you thinking about refactoring it?

steveburnett

LGTM! (docs)

Pull updated branch, new local build. Everything looks good.

hantangwangd · 2024-04-06T01:44:49Z

For reference, I agree with @ZacBlanco, use a separate commit for refactoring IcebergResourceFactory in the same PR would make the code more clearer.

kiersten-stokes · 2024-04-08T00:38:01Z

@ZacBlanco @hantangwangd love the idea of doing two separate commits. That would be the best of both worlds since I can keep it separate from the functionality but also get the refactor done sooner than later

As for the re-factor, there are certainly several ways to go about it. I'm currently (at least once I'm back from vacation) considering two methods. First is passing a newSetBinder to the IcebergResourceFactory and accessing the relevant methods from there. This may be a bit easier. The second method is probably more involved, separating out each type of Iceberg catalog into it's own module and extending all the relevant classes from there (I think just config and resource factory's getCatalogProperties, though I haven't delved deep into this yet).

Please feel free to suggest additional ways and to weigh in on the above! As mentioned, I won't be back to this in another day or two 🙂

ZacBlanco · 2024-04-16T13:34:04Z

I took a brief look. Re-factor overall looks good! I will perform a detailed review once out of draft stage

hantangwangd · 2024-05-13T16:19:10Z

Hi @kiersten-stokes, can you rebase your branch onto the newest master branch? it's a bit too far behind :-).

steveburnett · 2024-05-14T13:54:58Z

nit, suggest adding PR # into each item of the release note entry:

Pull updated branch, new local docs build, looks good!

hantangwangd

Thank you for adding this great feature. I took a look at the first commit, overall it looks good to me. But I'm a little confused by the large amount of error logs printed by the test cases.

After check the code, I found that the error log is printed by RESTCatalogServlet, and by comparing the test implementations of Iceberg and Trino, I notice that they both use certain methods to hide these error messages (that is to say, the error messages are still logged, but not displayed). Iceberg inject a NOPLogger, while Trino overwrite the servlet RestCatalogServlet and injected its own configurable io.airlift.log.Logger.

So should we as well do something to get rid of these annoying error messages? What's your opinion?

ZacBlanco

mostly just nits

+        restJdbcBackend.setConf(hdfsEnvironment.getConfiguration(new HdfsContext(SESSION), new Path(location.getAbsolutePath())));
+
+        Map<String, String> properties = ImmutableMap.<String, String>builder()
+                .put(URI, "jdbc:h2:mem:test" + System.nanoTime() + "_" + ThreadLocalRandom.current().nextInt())


nit: will we actually need nanoTime and a random variable? - also, maybe add another underscore between :test and `System.nanoTime()

Agreed that both is probably overkill, although this pattern came up a few different times in other tests that use this type of catalog. I was guessing it was a 'better safe than sorry' situation. Definitely agree on the underscore!

hantangwangd

I just took a whole look at all the commits, it's a very pretty refactoring, overall looks good to me. Just one thing for discussion, and some nits.

hantangwangd

Thanks for the fix, only some little nits. Again, it's a very pretty refactoring, make things more clearer.

Make nessie config optional in session properties

hantangwangd

LGTM, thanks for the great work.

Awesome refactor and nice work--thank you!
