huaxingao opened a new pull request #34148:
URL: https://github.com/apache/spark/pull/34148
### What changes were proposed in this pull request?
This is the 2nd PR for DSv2 index support.
This PR adds the following:
- create index syntax support in parser and analyzer
- `CreateIndex` logic node
- `CreateIndexExec` physical node
`CreateIndex` is not implemented yet in this PR. Calling `CreateIndex` will
throw `SQLFeatureNotSupportedException`, and the parsed index information such
as `IndexName` `indexType` `columns` and index properties will be included in
the error message for now for testing purpose.
### Why are the changes needed?
To support index in DSv2
### Does this PR introduce _any_ user-facing change?
Yes, the create table syntax as the following:
```
CREATE [index_type] INDEX [index_name] ON [TABLE] table_name
(column_index_property_list)[OPTIONS indexPropertyList]
column_index_property_list: column_name [OPTIONS(indexPropertyList)] [
, . . . ]
indexPropertyList: index_property_name = index_property_value [ , . . .
]
```
### How was this patch tested?
