[I] [SUPPORT] RFC 63 Functional Index Hudi 0.1.0-beta [hudi]
soumilshah1995 opened a new issue, #10110:
URL: https://github.com/apache/hudi/issues/10110
"Hello, I am currently exploring the new Functional Index features as outlined in the RFC.
Below is an example of my code, but I am unsure if I am correctly implementing the functional index. I'm not familiar with the exact syntax, and I would greatly appreciate your assistance.
My Hudi tables have been created, and I need guidance on how to properly create a functional index on the 'ts' (timestamp) column. Any help you can provide would be highly appreciated."

Here is the entirety of my code, and I'm encountering persistent issues. I attempted to contact you through a personal message on Slack for more rapid communication, hoping to expedite the resolution process. Please inform me if I've made any errors, as I'm still in the early stages of learning and might be overlooking certain aspects. I'm eager to learn, progress, and eventually contribute my knowledge to the Hudi community.

It should work with 1.0.0-beta1 with spark-sql. In the DDL page, I have provided an example with `hour` function. You can replace it with `from_unixtime`. This is what I tried and it works.

Hi @soumilshah1995 , thanks for giving it a try! Currently, the `FUNCTION` keyword is not integrated. I need to update the RFC with the exact syntax which can be found here in the SQL DDL docs - https://hudi.apache.org/docs/next/sql_ddl#create-index-experimental
We are tracking the issue to simplify the syntax. Ideally, we want users to be able to just say `CREATE INDEX func_index_abc on xyz_hudi_table USING column_stats(hour(ts))` without using `FUNCTION` keyword or provide extra options to specify the function. We will have it in 1.0 GA. Feel free to reach out to me directly on Hudi Slack if you're more interested in this feature.

Vinay, the problem I'm facing is that I struggle with building the JAR myself due to java versions conflicts . That's why I've resorted to using the packaged version to incorporate Hudi 1.0.0-beta. I recall Sagar mentioning that there were some issues with it. He did assure me that they were resolved in the master branch, and he also hinted that the official release would be coming soon. Given these remarks, I'm inclined to think that this version still has some bugs
I've attached the chats for your reference.
<img width="918" alt="image" src="https://github.com/apache/hudi/assets/39345855/8c84a852-38db-40ee-9c99-4091dd81bb7c">
Regarding our options:
Option A) I could wait for the beta 2 release.
Option B) If it's possible, could you send me the Jar files for Spark 3.4? That way, I can give it a try.
I'm fine with waiting, but if you can provide the Jar files, that works too. Let me know what works best for you.

agar, could you guide me on which metrics I should focus on? Specifically, should I be looking at query execution time or the total amount of data scanned? What are the key metrics I should pay attention to?

Thanks for trying it out. This seems like a different issue (rather than the spark analysis error that you were seeing earlier).
The error reported now is that the base files for the table are not found (in the specified location/path) i.e "file:/072fb7a1-bbd2-481a-9c7a-3ab3e3a70e68-0_11-31-0_20240327082222863.parquet" is not being found to build the index. I think you should give the correct `path` for the external table. Something like `df.write.format("hudi").options(**hudi_options).option("path","/full/path/to/external/table/location/").mode("append").saveAsTable("table_name")`

@soumilshah1995 There is a bit of issue with your query I guess. I tried below code for which the parsing works. Although facing some other problem. `No plan for CreateIndex hudi_func_index_01a19d91_699f_4ead_afe1_82a232f91efa_datestr, column_stats, false,` Can you try once.

I believe there's no need to create a new GitHub issue. The title clearly indicates the issue with beta1, a matter that Sagar and Aditya have confirmed previously. I'd suggest keeping the existing issue open for easier tracking, ensuring that all conversation threads remain consolidated within this GitHub thread.

If someone could help me understand how to verify that functional indexes are working, I would greatly appreciate it. I'm not an expert in Spark UI, so any guidance or pointers would be very helpful.

Is this a good example to observe a reduction in the number of files read before and after creating a functional index? If not, what changes should I make to the dataset or my query method to clearly see a decrease in the number of files read? I look forward to your guidance on this.

Re: [I] [SUPPORT] RFC 63 Functional Index Hudi 0.1.0-beta [hudi]

bhat-vinay commented on issue #10110:
URL: https://github.com/apache/hudi/issues/10110#issuecomment-2020640947
The issue is that `spark.read.format("hudi").load(PATH).createOrReplaceTempView(TABLE_NAME)` creates a temporary view (similar to the one that is created using `CREATE TEMPorary VIEW ...`) and it is neither a table and not a hudi managed table. Hence the following `CREATE INDEX ...` statement to create a functional fails as the object on which the index is being created is not a hudi managed table.
Instead of creating a temporary view, one can use `saveAsTable(...)` method on the DataFrameWriter object to create a hudi managed table and then create functional index on those tables. Please see if this works for you:
```
df.write.format("hudi").options(**hudi_options).option("path", "/external/table/path").mode("append").saveAsTable("table_name")
spark.sql(s"CREATE INDEX hudi_table_func_index_datestr ON table_name USING column_stats(ts) options(func='from_unixtime', format='yyyy-MM-dd')")
```

I do see difference in query time its faster what else I should see to ensure this is working as expected ?

Hi @soumilshah1995 , there are two things you can look at. First when you do EXPLAIN ANALYZE, the plan should show that it is using `HoodieFileIndex`. Second, the "number of files read" in Spark UI should show lesser number of files if any files were skipped using functional index (or any index for that matter). Another way is to enable debug logs for org.apache.hudi package when you launch spark-sql, and then upon executing the query, you will see something called "skipping ratio" which tells you the percentage of files skipped. Note that if the files are already pruned due to parition pruning, and then all of those pruned files need to be scanned as per the query predicate, then skipping ratio can be 0. Only when there is additional file pruning on top of partition pruning, you will find that skipping ratio is positive.

```
The above lines indicate that the basepath for the file was created in "file:/Users/soumilshah/Desktop/hudidemo/.hoodie/metadata", but the the functional-index build process is trying to read a data file from "file:/f113c72e-9bf6-4ab1-84b4-b2e9467142a8-0_11-68-0_20240327141353398.parquet". Please try removing the 'file:///' prefix from the path and retry i.e path should be `/Users/soumilshah/Desktop/hudidemo/` If you still see the problem, please open a new issue. As I mentioned earlier, the issue you are seeing now is not the same as the original issue that you reported (trying to build index on a temporary view).

Thanks for trying all the suggestions. I am unable to reproduce this in my environment. I will spend some time next week to setup the exact environment/versions you are using. In the mean time, would it be possible for you to run your tests against the latest master branch of Hudi and reproduce this? From the stack-trace below, I am not sure why the index build process is stripping the full path of the data file in your environment.

soumilshah1995 commented on issue #10110:
URL: https://github.com/apache/hudi/issues/10110#issuecomment-1814378726
would it work with Spark SQL on Hudi '1.0.0-beta1' or do we need to wait for '1.0.0-beta2' ?
can you please provide example in pyspark how to use it I cannot seem to get it to work
