------------------------------------
Summary: Upgrade Apache Lucene from version 6.6.6 to 9.x or higher
Key: GEODE-10471
URL: https://issues.apache.org/jira/browse/GEODE-10471
Project: Geode
Issue Type: Improvement
Reporter: Jinwoo Hwang
*Overview:* Apache Geode currently uses Apache Lucene 6.6.6 for its full-text
search capabilities through the
[geode-lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html]
module. This version is significantly outdated and should be upgraded to
Lucene 9.x or higher to benefit from performance improvements, security fixes,
new features, and continued community support.
*Current State:*
* *Current Version:* Apache Lucene 6.6.6 (defined in dependency management
configuration)
* *Affected Artifacts:*

*Impact Assessment:* The
[geode-lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html]
module provides critical functionality for:
* Creating and managing Lucene indexes on Geode regions
* Full-text search capabilities via
[LuceneQuery|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html]
API
* Text analysis and tokenization through various analyzers
* GFSH command-line interface for Lucene operations ([search
lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html],
[list
lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html],
[create lucene
index|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html],
etc.)
* Integration with Geode's distributed architecture
*Benefits of Upgrading:*
# *Performance Improvements:* Lucene 9.x includes significant performance
optimizations for indexing and search operations
# *Security:* Access to latest security patches and vulnerability fixes
# *New Features:* Enhanced query capabilities, improved analyzers, and better
memory management
# *Long-term Support:* Lucene 6.6.6 is no longer maintained; upgrading ensures
ongoing community support
# *Java Compatibility:* Better support for newer Java versions
*Migration Considerations:*
# *API Changes:* Review Lucene 9.x migration guide for potential breaking
changes in APIs used by Geode
# *Index Compatibility:* Evaluate if existing Lucene indexes created with
6.6.6 are compatible with 9.x or require reindexing
# *Analyzer Changes:* Verify that custom and built-in analyzers work correctly
with the new version
# *Test Impact:* Extensive testing of all Lucene-related functionality in
integration, distributed, and upgrade tests
# *Performance Validation:* Benchmark performance before and after upgrade to
ensure no regressions
*Files to Update:*
* Dependency management configuration files
* Any direct Lucene API usage in
[geode-lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html]
module source code
* Related test cases and integration tests
* Documentation updates for any API changes
*Testing Strategy:*
* Run all existing
[geode-lucene|vscode-file://vscode-app/Applications/Visual%20Studio%20Code.app/Contents/Resources/app/out/vs/code/electron-browser/workbench/workbench.html]
test suites (unit, integration, distributed, upgrade tests)
* Validate CLI functionality through GFSH integration tests
* Performance testing to ensure no degradation in search/indexing operations
* Rolling upgrade tests to ensure backward compatibility during cluster
upgrades
*Acceptance Criteria:*
* All Lucene dependencies upgraded to 9.x version
* All existing tests pass with new Lucene version
* No performance regressions in search/indexing operations
* GFSH Lucene commands continue to function correctly
* Documentation updated to reflect any API changes
* Rolling upgrade compatibility maintained
