### Change Logs _Describe context and summary for this change. Highlight if any code was copied._ ### Impact Inside HoodieTableMetadata.java, for index lookup APIs of SI and RLI only, input output all use HoodieData/HoodieMapData instead of Java collections. This is a pure interface level change, where the caller and API internal implementation still uses Java collections but wrap/unwrap the HoodieData/HoodieMapData interface. At the same time, introduced a new table version and did a quick code change on how secondary index file group partitioning is changed. Secondary index data format is `<secondary col value>$<record col value>: null` - Before table version 9, it is hash partition by `<secondary col value>$<record col value>` - Starting from table version 9, it is hash partitioned by `<secondary col value>` ### Risk level (write none, low medium or high below) none ### Documentation Update None ### Contributor's checklist - [ ] Read through [contributor's guide](https://hudi.apache.org/contribute/how-to-contribute) - [ ] Change Logs and Impact were stated clearly - [ ] Adequate tests were added if applicable - [ ] CI passed -- This is an automated message from the Apache Git Service.
