描述

We should enhance index type compatibility check in table config validation. E.g. inverted index enabled column must have dictionary enabled.

We should list down all supported index types, and do an exhaustive check on all incompatible combinations.

For code reference, table config validation is performed in TableConfigUtils.validate(TableConfig tableConfig, Schema schema)

研究方向
The issue is to enhance index type compatibility validation in TableConfigUtils.validate(). First, identify all supported index types in Pinot (e.g., inverted, sorted, text, etc.) by reviewing documentation or source code. Then, list all incompatible combinations (e.g., inverted index requires dictionary enabled). The existing validation logic is in TableConfigUtils.validate(TableConfig, Schema). Implement exhaustive checks for each combination. Since the issue has an assignee, check the linked PR or discussion for any progress. The codebase uses Java, so contribute by writing unit tests or extending the validation method.
