Short Description Provides a cache backend for TYPO3 that stores all cache information in Lucene
License GPL-2.0-or-later
FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Use Lucene as Cache Backend for your TYPO3 projects
Provides a cache backend for TYPO3 that stores all cache information in Lucene index.
Key Features of lucene-cache for TYPO3
- Efficient Caching: Uses Lucene's indexing and search capabilities to store and retrieve cached content quickly.
- Scalability: Can handle large volumes of data and perform well under high load, making it suitable for large TYPO3 installations.
- Flexibility: Provides flexible configuration options to tailor the caching behavior to specific needs.
- Integration: Seamlessly integrates with TYPO3's caching framework, allowing for easy setup and use within TYPO3 projects.
Installation and Configuration
To use the lucene-cache backend in your TYPO3 project, follow these steps:
Install the Extension
You can install the lucene-cache extension via Composer:
Example Configuration for the Cache
Performance
The issue to develop that cache was a usage of very many cache tags.
maxBufferedDocs is set to 1000 here, that means that up to 1000 documents are buffered before to write, that is good for large imports if you have some spare ram. Meanwhile, that caching information is not available to other PHP processes.
Keep in mind that some operations (flushes and garbage collection) will always commit the buffer first to have a full index to search in.
compression
Enable compression to reduce disk space usage. The extension supports multiple compression algorithms and will auto-detect the best available one.
Available algorithms (in order of preference):
| Algorithm | Speed | Ratio | Requirement |
|---|---|---|---|
zstd |
⚡ Fast | Excellent | ext-zstd |
gzdeflate |
Medium | Good | ext-zlib |
gzcompress |
Medium | Good | ext-zlib |
- Auto-detection: If
compressionAlgorithmis not set, the best available algorithm is used automatically. - Minimum size: Data smaller than
compressionMinSizebytes is not compressed (overhead not worth it). - Backward compatible: Existing caches using legacy
gzcompresswill still decompress correctly.
