jira-importer commented on issue #546: URL: https://github.com/apache/maven-indexer/issues/546#issuecomment-2965150515
**[Thomas Kruse](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=everflux)** commented I have used it inside of Netbeans 8.0/dev and compared it to the original maven-indexer. Result: Size on disc: Using old lucene: 6.9G Using newer lucene: 3.1GB The reason for this is that Lucene introduced codecs, by default a compression codec is enabled. This is especially beneficial for storing field content which is what maven indexer is doing. I can not say if there is any performance or memory (RAM) improvement. The upgrade breaks compatibility with very old lucene indices. That is used as interchange format for old(!) maven repository index (.zip extension). The new interchange format (.gz extension) is using a custom text file format which is used to build the Lucene index during import. I am already aware of some issues with my initial pull request, all are related to the pom.xml - I will fix that and create a new PR. -- This is an automated message from the Apache Git Service.
