From a97baa24d1f15cad2e04e4c48a7f6dc2cced973a Mon Sep 17 00:00:00 2001 From: kaori-seasons Date: Tue, 20 Jan 2026 14:22:50 +0800 Subject: [PATCH 1/5] feat: add catalog namespace support This commit introduces a new namespace abstraction layer for Lance catalog integration with Flink. Key components added: - AbstractLanceNamespaceAdapter: Interface defining namespace operations - LanceNamespaceAdapter: Implementation with direct Lance Namespace SDK API calls - LanceNamespaceConfig: Type-safe configuration management with ImplType enum - BaseLanceNamespaceCatalog: Base catalog implementation for Flink integration - LanceNamespaceAdapterITCase: Comprehensive integration tests (23 test cases) - MockLanceNamespace: Mock implementation for standalone testing Features: - Direct API calls to Lance Namespace SDK (no reflection) - Support for both directory and REST namespace implementations - Complete CRUD operations for namespaces and tables - Full metadata management - Production-ready error handling and resource management --- .../AbstractLanceNamespaceAdapter.java | 112 ++++ .../namespace/BaseLanceNamespaceCatalog.java | 84 +++ .../namespace/LanceNamespaceAdapter.java | 353 ++++++++++ .../namespace/LanceNamespaceConfig.java | 444 +++++++++++++ .../LanceNamespaceAdapterITCase.java | 616 ++++++++++++++++++ .../catalog/namespace/MockLanceNamespace.java | 327 ++++++++++ 6 files changed, 1936 insertions(+) create mode 100644 src/main/java/org/apache/flink/connector/lance/catalog/namespace/AbstractLanceNamespaceAdapter.java create mode 100644 src/main/java/org/apache/flink/connector/lance/catalog/namespace/BaseLanceNamespaceCatalog.java create mode 100644 src/main/java/org/apache/flink/connector/lance/catalog/namespace/LanceNamespaceAdapter.java create mode 100644 src/main/java/org/apache/flink/connector/lance/catalog/namespace/LanceNamespaceConfig.java create mode 100644 src/test/java/org/apache/flink/connector/lance/catalog/namespace/LanceNamespaceAdapterITCase.java create mode 100644 src/test/java/org/apache/flink/connector/lance/catalog/namespace/MockLanceNamespace.java diff --git a/src/main/java/org/apache/flink/connector/lance/catalog/namespace/AbstractLanceNamespaceAdapter.java b/src/main/java/org/apache/flink/connector/lance/catalog/namespace/AbstractLanceNamespaceAdapter.java new file mode 100644 index 0000000..dc46c3b --- /dev/null +++ b/src/main/java/org/apache/flink/connector/lance/catalog/namespace/AbstractLanceNamespaceAdapter.java @@ -0,0 +1,112 @@ +/* + * Licensed to the Apache Software Foundation (ASF) under one + * or more contributor license agreements.

Convert to multi-module Maven project with version-specific modules - Each module (lance-flink-1.17/1.18/1.19/1.20) compiles shared src/ with its Flink version - Use build-helper-maven-plugin to reference shared source and resources - All modules compile with Java 8 target (consistent with Flink official builds) - Add maven-enforcer-plugin for Maven/JDK version and dependency checks - Add spotless-maven-plugin for code formatting and license header checks - Remove unused TableSchema import in LanceDynamicTableSource - Remove duplicate SPI files from version modules (already referenced via build-helper) - Remove unnecessary lance-flink-base module (code already in shared src/) - Remove JDK-based Maven profiles (all modules now build uniformly) --- .gitignore | 5 +- lance-flink-1.17/pom.xml | 244 ++++++ .../src/test/resources/log4j2-test.xml | 15 + lance-flink-1.18/pom.xml | 244 ++++++ .../src/test/resources/log4j2-test.xml | 15 + lance-flink-1.19/pom.xml | 243 ++++++ .../src/test/resources/log4j2-test.xml | 15 + lance-flink-1.20/pom.xml | 243 ++++++ .../src/test/resources/log4j2-test.xml | 15 + pom.xml | 743 ++++++++++-------- .../lance/table/LanceDynamicTableSource.java | 1 -
