説明

I have a question on capturing lineage for operations that are not Written, but reads are still performed.

Take for example this code:
`result = spark.sql("select * from hive.table limit 1").collect()`

Has a materialized dataframe, which could be used to parameterize subsequent queries, or produce reports or datasets that may be written to resources outside spark, but I don't believe lineage is captured via Spline.

We have quite a few use cases where we want to capture lineage in this scenario and want to gauge what it may take for these lineage records to flow to the `LineageDispatcher`. We are using a custom LineageDispatcher for our case as well. Additionally we will be adding additional "Meta Information" to these lineage records so that they still have "Attribution" to the Job(code) or User who performed the read or write.

Thanks, I understand why Spline doesn't capture Lineage without a write, as it's a Dataset to Dataset lineage tool, but want to start a discussion to understand what may be needed to enable this, or if it's realistic in general.

Thanks for the advice.
