Subject: [PATCH 1/2] chore: remove IDE artifacts from version control
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The repository had 9 `.idea/` files committed against intent,
totaling ~7.5 MB — dominated by `.idea/CopilotChatHistory.xml`
(7.4 MB of AI chat history). The previous `.gitignore` enumerated
`.idea/X.xml` entries piecemeal, which let other IDE files
(encodings.xml, misc.xml, vcs.xml, codeStyles/, etc.) slip in.

This commit:

- Replaces the piecemeal `.idea/X.xml` block with a blanket
  `.idea` ignore plus symmetric `out/` handling, mirroring
  the sister repo `lance-format/lance-spark`.
- Runs `git rm --cached` on all 9 tracked `.idea/` files.
  They remain on disk for local IntelliJ use but are no longer
  under version control.

IDE-level codestyle (`.idea/codeStyles/*.xml`) is removed
intentionally: the planned Spotless + google-java-format
adoption will be the single source of truth for formatting;
a separate IDE codestyle in git would diverge over time.

[LanceCatalogFactory.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/table/LanceCatalogFactory.java)\n\n新增了以下 S3 配置选项：\n\n| 配置项 | 类型 | 描述 |\n|--------|------|------|\n| `s3-access-key` | String | S3 Access Key ID |\n| `s3-secret-key` | String | S3 Secret Access Key |\n| `s3-region` | String | S3 Region（如 us-east-1） |\n| `s3-endpoint` | String | S3 Endpoint URL（用于兼容 S3 协议的存储，如 MinIO） |\n| `s3-virtual-hosted-style` | Boolean | 是否使用虚拟主机风格的 URL（默认 true） |\n| `s3-allow-http` | Boolean | 是否允许 HTTP 连接（默认 false） |\n\n### 2. [LanceCatalog.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/table/LanceCatalog.java)\n\n主要改动：\n- 新增 `storageOptions` 字段存储 S3 配置\n- 新增 `isRemoteStorage` 字段标识是否为远程存储\n- 新增支持远程存储的构造函数\n- 添加 `isRemotePath()` 方法判断是否为远程路径（支持 s3://, s3a://, gs://, az:// 等）\n- 添加 `configureStorageEnvironment()` 方法配置存储环境变量\n- 对于远程存储，使用内存缓存 `knownDatabases` 和 `knownTables` 跟踪数据库和表\n\n### 使用示例\n\n**本地存储（保持原有方式）**：\n```sql\nCREATE CATALOG lance_local WITH (\n    'type' = 'lance',\n    'warehouse' = '/path/to/warehouse',\n    'default-database' = 'default'\n);\n```\n\n**S3 存储（新增支持）**：\n```sql\nCREATE CATALOG lance_s3 WITH (\n    'type' = 'lance',\n    'warehouse' = 's3://my-bucket/lance-warehouse',\n    'default-database' = 'default',\n    's3-access-key' = 'AKIAXXXXXXXX',\n    's3-secret-key' = 'your-secret-key',\n    's3-region' = 'us-east-1'\n);\n\n-- 使用 MinIO 等兼容 S3 协议的存储\nCREATE CATALOG lance_minio WITH (\n    'type' = 'lance',\n    'warehouse' = 's3://my-bucket/lance-warehouse',\n    'default-database' = 'default',\n    's3-access-key' = 'minioadmin',\n    's3-secret-key' = 'minioadmin',\n    's3-endpoint' = 'http://localhost:9000',\n    's3-allow-http' = 'true',\n    's3-virtual-hosted-style' = 'false'\n);\n```\n\n### 注意事项\n\n1. **远程存储限制**：\n   - 删除表只会移除 Catalog 中的记录，实际数据需要手动从云存储中删除\n   - 不支持重命名远程存储中的表\n\n2. **环境变量**：Lance SDK 底层使用环境变量配置 S3 凭证，代码中通过 `System.setProperty` 设置&quot;},&quot;timestamp&quot;:1767452155,&quot;type&quot;:&quot;TEXT_MESSAGE_CONTENT&quot;}" />

[LanceSource.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceSource.java)\n- 将 `com.lancedb.lance.DatasetFragment` 改为 `com.lancedb.lance.Fragment`\n- 将 `scanOptionsBuilder.columns(selectedColumns)` 改为 `scanOptionsBuilder.columns(Arrays.asList(selectedColumns))`\n\n### 2. [LanceInputFormat.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceInputFormat.java)\n- 将 `DatasetFragment` 改为 `Fragment`\n- 移除了 `FragmentMetadata` 的导入（Fragment 没有公开的 getMetadata() 方法）\n- 使用 `fragment.countRows()` 替代 `metadata.getPhysicalRows()`\n- 修复了 `columns()` 方法调用\n\n### 3. [LanceIndexBuilder.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceIndexBuilder.java)\n- 移除了不存在的 `IvfPqIndexBuilder`, `IvfHnswPqIndexBuilder`, `IvfFlatIndexBuilder` 类\n- 使用正确的 API：`Dataset.createIndex()` 配合 `IndexType`, `IndexParams`, `VectorIndexParams`\n\n### 4. [LanceVectorSearch.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceVectorSearch.java)\n- 将 `Query.Builder.setVector()` 改为 `setKey()`\n- 将 `Query.Builder.setDistanceType(String)` 改为 `setDistanceType(DistanceType)`\n- 使用 `ScanOptions.Builder.nearest(Query)` 和 `dataset.newScan(ScanOptions)` 替代不存在的 `dataset.search()`\n\n### 5. [LanceSink.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceSink.java)\n- 移除了不存在的 `Dataset.write()` 方法\n- 使用正确的写入 API：`Fragment.create()` + `FragmentOperation.Append/Overwrite.commit()`\n\n### 6. [pom.xml](/Users/rockybx/codebuddy/flink-lance-test/pom.xml)\n- 将 Java 版本从 11 改为 1.8 以兼容当前环境\n\n项目现在可以成功编译了！&quot;},&quot;timestamp&quot;:1767094665,&quot;type&quot;:&quot;TEXT_MESSAGE_CONTENT&quot;}" />

[LanceDynamicTableSource.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/table/LanceDynamicTableSource.java)\n- 完全重写了 `convertToLanceFilter()` 方法\n- 添加了 `convertCallExpression()` 解析 Flink 函数调用\n- 添加了 `buildComparisonFilter()` 构建比较表达式\n- 添加了 `buildLogicalFilter()` 构建逻辑表达式\n- 添加了 `extractLiteralValue()` 提取字面量值\n\n**支持的过滤操作：**\n| Flink 表达式 | 转换后 Lance SQL |\n|-------------|-----------------|\n| `equals(a, 'b')` | `a = 'b'` |\n| `notEquals(a, 1)` | `a != 1` |\n| `greaterThan(a, 10)` | `a &gt; 10` |\n| `lessThan(a, 5)` | `a &lt; 5` |\n| `and(expr1, expr2)` | `(expr1) AND (expr2)` |\n| `or(expr1, expr2)` | `(expr1) OR (expr2)` |\n| `isNull(a)` | `a IS NULL` |\n| `isNotNull(a)` | `a IS NOT NULL` |\n| `like(a, '%test%')` | `a LIKE '%test%'` |\n\n#### 2. [LanceSource.java](/Users/rockybx/codebuddy/flink-lance-test/src/main/java/org/apache/flink/connector/lance/LanceSource.java)\n- 添加了 `readDatasetWithFilter()` 方法，使用 Dataset 级别扫描\n- 修改了 `run()` 方法逻辑：\n  - **有 filter 时**：使用 `Dataset.newScan(ScanOptions)` 进行扫描\n  - **无 filter 时**：使用 `Fragment.newScan()` 进行并行分片扫描\n\n---\n\n现在您可以重新运行测试：\n```bash\nmvn test -Dtest=FlinkSqlDemo#testCompleteVectorExample\n```&quot;},&quot;timestamp&quot;:1767330043,&quot;type&quot;:&quot;TEXT_MESSAGE_CONTENT&quot;}" />

 dependency-reduced-pom.xml

The shade plugin writes dependency-reduced-pom.xml next to pom.xml on
every package build. Add it to .gitignore so it stops showing up as
untracked after `mvn package`.
