IMO, a for-loop can implement it.

Do we have the same method in TestStreamReadOperator?

Move to TestUtils.

I still think the old one is better. We should have the only fact source. If we define a new one, it would bring more cost of maintenance.

Not true, because HoodieTableType should never change.

I am not sure if a definition would be changed. But if we have a fact source, anywhere we reference it, it's enough. IMO, it's not necessary to define it more than once. Otherwise, the others would define it in java or spark module? Because, we allowed this behavior in flink module. It will add the complexity and the cost of understanding.

Spark did have a definition, see DataSourceOptions.COW_TABLE_TYPE_OPT_VAL and DataSourceOptions.MOR_TABLE_TYPE_OPT_VAL.

IMO, it's different. Spark referenced the HoodieTableType.COPY_ON_WRITE.name, but you used a string literal. What I mean about the word define, is to use a literal directly. In the future, if we change the value of HoodieTableType , in DataSourceOptions we do not need to search the string literal, and we can control all the change points.

HoodieTableType is an enumeration, but in many cases we need a string constant, not a method call like HoodieTableType.name(), such as the Junit5 parameterized test.
BTW, can we not block this PR because these two options are now introduced in this PR though. We can discuss it in another issue, i think, this is not a critical issue.

We did not block the PR because of the reason for this divergence. And why do not we learn from DataSourceOptions ?

It would be better to add READ_.

IMO, this log missed some key information, for example, table, path, and so on.

ditto, we need more information in the log.

Do we really need to log each split even for a big table?

IMO, if we choose to throw the exception, it's not necessary to log it. Even if we want to log it, it would be better to use error level.

@yanghua sorry, too busy at work. Might have to miss this PR. |
Supports two read modes: * Read the full data set starting from the latest commit instant and subsequent incremental data set * Read data set that starts from a specified commit instant

OK, understood, I have been also busy recently. |
