Y Ethan Guo commented on HUDI-7896:
-----------------------------------
We have backwards compactible writer support in Hudi 1.0, i.e., Hudi 1.0 writer
writing Hudi table with table version 6. This is no longer needed for the
migration.
> Add tests to validate 1.x tables are readable with 0.16.0 hudi

> Key: HUDI-7896
> URL: https://issues.apache.org/jira/browse/HUDI-7896
> Project: Apache Hudi
> Issue Type: Sub-task
> Components: tests-ci
> Reporter: sivabalan narayanan
> Assignee: sivabalan narayanan
> Priority: Major
>
> We need tests added to 0.16.0 hudi to ensure it can read 1.x tables.
>
> We should have good coverage for all new log formats, diff table types,
> pending compactions, pending clustering, completed clustering, failed
> commits/delta commits, pending rollbacks, pending cleans etc. diff payloads,
> key gen, partitioned/non-partitioned. regular index and global index.
> Cover all different writers:
> a. spark ds writer
> b. spark sql
> c. deltastreamer
> d. spark streaming writer
>
>
>
> Reader side validation:
> lets account for snapshot read, incremental read, time travel read.
