huaxingao opened a new pull request #34164: URL: https://github.com/apache/spark/pull/34164
### What changes were proposed in this pull request? Implementing `createIndex`/`IndexExists` in DS V2 JDBC ### Why are the changes needed? This is a subtask of the V2 Index support. I am implementing index support for DS V2 JDBC so we can have a POC and an end to end testing. This PR implements `createIndex` and `IndexExists`. Next PR will implement `listIndexes` and `dropIndex`. I intentionally make the PR small so it's easier to review. Index is not supported by h2 database and create/drop index are not standard SQL syntax. This PR only implements `createIndex` and `IndexExists` in `MySQL` dialect. ### Does this PR introduce _any_ user-facing change? Yes, `createIndex`/`IndexExist` in DS V2 JDBC ### How was this patch tested? new test -- This is an automated message from the Apache Git Service.
