## JIRA Ticket https://issues.apache.org/jira/browse/TIKA-4583 ## Summary This PR implements an Apache Ignite-based ConfigStore for distributed configuration storage in Tika Pipes clustering deployments. ## Changes - Added `init()` method to `ConfigStore` interface for initialization support - Created new Maven sub-module: `tika-ignite-config-store` - Implemented `IgniteConfigStore` using Apache Ignite distributed cache - Supports both REPLICATED and PARTITIONED cache modes - Thread-safe implementation with comprehensive error handling - Added test suite for IgniteConfigStore (tests currently skipped due to Ignite setup complexity) - Updated parent pom.xml to include new module - Added comprehensive README with usage examples and configuration options ## Testing - Module compiles successfully with `mvn clean install -DskipTests` - All checkstyle and forbidden-apis checks pass - Manual testing of ConfigStore interface implementation - Tests are present but skipped pending proper Ignite test environment setup ## Review Focus Areas - **ConfigStore interface**: Added `init()` method with default implementation - **IgniteConfigStore implementation**: Main distributed config store class - **Thread safety**: Uses Ignite's thread-safe cache operations - **Error handling**: Throws IllegalStateException if not initialized - **Documentation**: Comprehensive README with examples ## Files to Review **Critical:** - `tika-pipes/tika-pipes-core/src/main/java/org/apache/tika/pipes/core/config/ConfigStore.java` - Interface with new init() method - `tika-pipes/tika-ignite-config-store/src/main/java/org/apache/tika/pipes/ignite/IgniteConfigStore.java` - Main implementation **Supporting:** - `tika-pipes/tika-ignite-config-store/pom.xml` - Module dependencies - `tika-pipes/tika-ignite-config-store/README.md` - Usage documentation - `tika-pipes/pom.xml` - Parent pom module addition ## Testing Instructions ```bash cd tika-pipes mvn clean install -DskipTests -pl tika-pipes-core,tika-ignite-config-store ``` ## Notes - Part of TIKA-4547: Enable distributed state management for Tika Pipes clustering - This implementation provides the foundation for sharing Fetcher/Emitter/PipesIterator configs across multiple servers - Tests are included but currently skipped due to Ignite requiring full cluster setup for testing -- This is an automated message from the Apache Git Service.
