## Summary of Changes Hello @Suvrat1629, I'm Gemini Code Assist[^1]! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request addresses a critical bug in the CassandraIO connector that prevented successful data reads from Cassandra tables where column names conflicted with CQL reserved keywords. By introducing a robust identifier quoting mechanism, the connector now correctly generates CQL queries, ensuring compatibility and reliable data extraction from such tables. The change significantly enhances the connector's resilience and broadens its applicability to a wider range of Cassandra schema designs. ### Highlights * **CassandraIO Fix**: Resolved an issue in `CassandraIO.ReadFn` where reading from tables with column names that are Cassandra reserved keywords (e.g., "true", "key", "select") would fail due to incorrect CQL query generation. * **Identifier Quoting**: Implemented proper quoting of column names with double quotes in generated CQL queries. This ensures that reserved keywords are treated as identifiers and not as part of the CQL syntax. * **New Utility Method**: Introduced a `quoteIdentifier` static method in `ReadFn` to encapsulate the logic for correctly quoting and escaping identifiers, handling cases with existing double quotes by doubling them. * **Comprehensive Testing**: Added extensive unit and integration tests covering various scenarios, including the `quoteIdentifier` method itself, reading from tables with reserved keyword columns, custom queries involving reserved keywords, multiple reserved keyword partition keys, and ensuring backward compatibility with normal identifiers. <details> <summary><b>Using Gemini Code Assist</b></summary> <br> The full guide for Gemini Code Assist can be found on our [documentation page](https://developers.google.com/gemini-code-assist/docs/review-github-code), here are some quick tips. <b>Invoking Gemini</b> You can request assistance from Gemini at any point by creating a comment using either `/gemini <command>` or `@gemini-code-assist <command>`.
