## Summary of Changes Hello @ahmedabu98, 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 significantly enhances the Apache Beam website by introducing extensive documentation for SQL Data Definition Language (DDL) commands, making it easier for users to understand and utilize SQL for managing Catalogs, Databases, and Tables. Concurrently, it refines the Iceberg SQL connector's ability to handle table properties, including a new convention for Beam-specific configurations, and updates existing documentation to reflect these capabilities and new table types. ### Highlights * **New SQL DDL Documentation**: Comprehensive documentation has been added for Beam SQL Data Definition Language (DDL) commands, covering CREATE, DROP, USE, SHOW, and ALTER statements for Catalogs, Databases, and Tables. * **Iceberg Connector Enhancements**: The Iceberg SQL connector has been updated to support passing table properties during table creation and to correctly parse Beam-specific properties (prefixed with 'beam.write.' and 'beam.read.'). * **Website Navigation Update**: The Beam website's navigation menu has been updated to include a new 'DDL' section under Beam SQL, providing easy access to the newly added documentation. * **Expanded CREATE EXTERNAL TABLE Documentation**: The documentation for `CREATE EXTERNAL TABLE` now includes detailed sections for Iceberg and DataGen table types, explaining their syntax, properties, and usage. 🧠**New Feature in Public Preview:** You can now enable **Memory** to help **Gemini Code Assist** learn from your team's feedback. This makes future code reviews more consistent and personalized to your project's style. **Click [here](https://codeassist.google/code-review/login) to enable Memory in your admin console.** <details> <summary><b>Changelog</b></summary> * **sdks/java/extensions/sql/iceberg/src/main/java/org/apache/beam/sdk/extensions/sql/meta/provider/iceberg/IcebergMetastore.java** * Added imports for `Collectors` and `TypeReference`. * Modified `createTable` method to accept and process a `Map<String, String> properties` argument, filtering out Beam-specific properties before passing them to the Iceberg catalog. * **sdks/java/extensions/sql/iceberg/src/main/java/org/apache/beam/sdk/extensions/sql/meta/provider/iceberg/IcebergTable.java** * Added import for `JsonNode` and defined constants for `BEAM_WRITE_PROPERTY` and `BEAM_READ_PROPERTY`. * Refactored the constructor to iterate through table properties, identify Beam-specific properties (e.g., `beam.write.triggering_frequency_seconds`), and throw exceptions for unknown Beam properties. * **sdks/java/extensions/sql/iceberg/src/test/java/org/apache/beam/sdk/extensions/sql/meta/provider/iceberg/PubsubToIcebergIT.java** * Updated `TBLPROPERTIES` in test cases to use the new `beam.write.triggering_frequency_seconds` prefix for `triggering_frequency_seconds`. * **sdks/java/io/iceberg/src/main/java/org/apache/beam/sdk/io/iceberg/IcebergCatalogConfig.java** * Modified `createTable` method signature to include a `Map<String, String> properties` argument. * Passed the new `properties` argument to the underlying Iceberg `catalog().createTable` call. * **website/www/site/content/en/documentation/dsls/sql/ddl/alter.md** * Added new documentation for `ALTER CATALOG` and `ALTER TABLE` statements, including examples for column, partition, and property modifications. * **website/www/site/content/en/documentation/dsls/sql/ddl/create.md** * Added new documentation for `CREATE CATALOG`, `CREATE DATABASE`, and `CREATE TABLE` statements, with examples for Iceberg catalog and table creation, including Beam-specific properties. * **website/www/site/content/en/documentation/dsls/sql/ddl/drop.md** * Added new documentation for `DROP CATALOG`, `DROP DATABASE`, and `DROP TABLE` statements, explaining unregistration versus physical deletion. * **website/www/site/content/en/documentation/dsls/sql/ddl/overview.md** * Added a new overview document for Beam SQL DDL, explaining the three-tier namespace (Catalog, Database, Table) and linking to specific DDL command documentation. * **website/www/site/content/en/documentation/dsls/sql/ddl/show.md** * Added new documentation for `SHOW CATALOGS`, `SHOW DATABASES`, and `SHOW TABLES` statements, including examples for filtering and checking current context. * **website/www/site/content/en/documentation/dsls/sql/ddl/use.md** * Added new documentation for `USE CATALOG` and `USE DATABASE` statements, explaining how to set the active context. * **website/www/site/content/en/documentation/dsls/sql/extensions/create-catalog.md** * Added detailed documentation for `CREATE CATALOG` specifically for Apache Iceberg, covering syntax, required/optional properties for various catalog implementations (Hadoop, BigQuery, JDBC), and examples. Includes sections on using catalogs, management, best practices, and troubleshooting. * **website/www/site/content/en/documentation/dsls/sql/extensions/create-external-table.md** * Modified to include `iceberg` and `datagen` as supported `TYPE` values in the `CREATE EXTERNAL TABLE` syntax. * Added a new comprehensive section for `Apache Iceberg` table creation, covering syntax, read/write modes, schema mapping, and examples. * **website/www/site/layouts/partials/section-menu/en/sdks.html** * Modified to add a new collapsible 'DDL' section under 'Beam SQL' in the navigation menu, linking to the newly added DDL documentation pages. </details> <details> <summary><b>Activity</b></summary> * ahmedabu98 created this pull request to add SQL DDL documentation to the Beam website. * The changes include adding new markdown files for DDL commands (ALTER, CREATE, DROP, OVERVIEW, SHOW, USE) and a detailed `create-catalog.md`. * Existing Java code for Iceberg SQL integration was modified to support new table properties and their parsing. * Test cases for Iceberg were updated to reflect the new property naming conventions. * The website's navigation menu was updated to incorporate the new DDL documentation structure. </details> <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>`.
