@7c00 Thanks for the contribution. This would be pretty useful for the Hudi community.

I took one pass and left some comments. I have a high-level question. Can you please add to the description, what all Hudi table types and query types are currently supported?

presto-hudi/src/main/java/com/facebook/presto/hudi/RecordCursorUtil.java

Instead of reflection-based check, we can use annotations provided by Hudi. Check these two annotations in Hudi:

UseRecordReaderFromInputFormat UseFileSplitsFromInputFormat

The annotations UseRecordReaderFromInputFormat and UseFileSplitsFromInputFormat indicate that we could delegate the splitting to InputFormat. As we discussed in the design proposal, there are some performance issues in the splitting implementation from InputFormat. So we will ignore these annotations and provide a new splitting implementation optimized for Presto.

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiSplitManager.java

Not sure if you're considering different partition extractors in hudi-hive sync. Depending on partition extractor, partition values can change.

We are now retrieving partition metadata through HiveMetaStore, where the partition values stored have been extracted by some partition extractors from their partition locations and thus we dont need to take consisder of the partition extractors.

@pratyakshsharma @codope Thanks for your comments. I have updated the code as the comments. Could you please take a second review? Thanks in advance.

pratyakshsharma · 2022-02-20T12:54:23Z

@codope Can you please take another pass on this?

codope · 2022-02-21T05:46:06Z

@pratyakshsharma @codope Thanks for your comments. I have updated the code as the comments. Could you please take a second review? Thanks in advance.

Will review by Wednesday.

codope · 2022-02-25T12:09:05Z

@7c00 I have taken one more pass. The code look fine from Hudi perspective.
@arunthirupathi Could you or someone in the community help in taking this forward?

arunthirupathi · 2022-02-25T19:06:59Z

This contains 2 set of changes, changes to hive/metastore and hudi connector. Can you please do a PR for hive/metastore changes alone and hudi connector.

I will review the hive/metastore changes closely.
Hudi, if you folks are happy with it, I will glance through it and help you in merging.

7c00 · 2022-02-28T09:43:58Z

@arunthirupathi I have extracted the metastore related changes to a new PR at #17368. Could you take a review on it? Thank you in advance ❤️ .

7c00 · 2022-03-10T14:17:17Z

I have refactored the tests. Instead of dynamically generating tables during testing, the new tests are using the pre-generated data from Hudi Docker demo. The reasons for that are

it's hard to make PrestoExtendedFileSystemCache happy with HoodieWrapperFileSystem; the issue was walked around in a very tricky way;
HoodieJavaClient cannot create a MOR table with log files, which makes the tests imcomplete

@codope @pratyakshsharma Could you take a second review? Nearly all the changes comes from the test part. Then I'd like to invite Presto fellows to review the PR.

pratyakshsharma · 2022-03-10T15:28:24Z

I am actually travelling this weekend. Will take a look early next week.

arunthirupathi · 2022-03-10T17:28:18Z

What is the size of the jar that is getting built ?few 10's of MB is fine, but if it is producing really large then please look into it in reducing the size.

When it is ready for review, Please ping me again.

For specific connectors, we require it to be thoroughly reviewed by someone else familiar with the connector. Once that review is done, I will make a pass to ensure it meets the coding guidelines.

7c00 · 2022-04-11T07:14:40Z

@arunthirupathi Sorry for late to reply.

What is the size of the jar that is getting built ?few 10's of MB is fine, but if it is producing really large then please look into it in reducing the size.

As we are reusing dependencies from presto-hive module and have added no new dependency. The total size of this hudi connector will be less than that of hive connector.

When it is ready for review, Please ping me again.

For specific connectors, we require it to be thoroughly reviewed by someone else familiar with the connector. Once that review is done, I will make a pass to ensure it meets the coding guidelines.

Now this PR is blocked the Avro dependency issue (found in #17463) to be fixed in next Hudi release 0.11. When Hudi 0.11 is released, we are going to continue to work on this PR and invite you to review. Thanks you in advance.

@7c00 Hudi v0.11 is released https://mvnrepository.com/artifact/org.apache.hudi/hudi-presto-bundle/0.11.0
Can you please upgrade and rebase this PR?

7c00 · 2022-05-25T10:05:15Z

The code has been rebased to sync with master branch after #17463 . It's ready to review now.

@codope @pratyakshsharma @arunthirupathi @kewang1024 @highker Could you take a look at this PR? Thanks in advance! ❤️

pratyakshsharma · 2022-06-07T06:16:12Z

@pettyjamesm Please take a look when you get a chance.

arunthirupathi

Mostly looks good, left some nits.

Sorry my notification in Presto is messed up, I will fix it. so that I will have a quicker turn around time next time.

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiColumnHandle.java

Can you please StringHelper to convert to String ?

The toString method here is implemented followed the convention of HiveColumnHandle#toString. In this way, we could have a more compacted text (refer to a Hudi column) when output logs.

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiConnectorFactory.java

arunthirupathi · 2022-06-11T00:03:55Z

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiFile.java

Use toStringHelper

The same reason as HudiColumnHandle#toString

arunthirupathi · 2022-06-11T00:13:09Z

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiPageSource.java

This code though is right, is inefficient. This is one of the hot paths. If there is no prefilled blocks, short circuit and return the delegate page.

Good catch, thank you. Add short circuit when no actual prefilled block.

arunthirupathi · 2022-06-11T00:13:55Z

presto-hudi/src/main/java/com/facebook/presto/hudi/HudiPageSource.java

Add the value here on what was illegal, so that it makes debugging easier.

The IllegalArgumentException is catched later in current method, then a PrestoException with more context infomation is thrown.

arunthirupathi · 2022-06-11T00:15:37Z

Include the decimalPrecision and decimalType precision in the error message, along with the valueString.

The same reaseon as above.

codope · 2022-06-13T04:11:42Z

Thanks for reviewing @arunthirupathi
We'll address the comments shortly.

arunthirupathi · 2022-06-13T05:38:58Z

Looks like there were some changes and this was broken, can you please fix them as well ?

7c00 · 2022-06-13T06:02:46Z

@arunthirupathi Thanks for your reviewing. The comments have been addressed. Let me ping you again when all CI checks passed.

7c00 · 2022-06-13T07:06:29Z

Hey @arunthirupathi All CI passed. Let's merge this PR?

7c00 · 2022-06-14T01:41:45Z
