Solr 7.4 steht in den Startlöchern
Laut GitHub steht Solr 7.4.0 als nächstes Release fest.
Folgende Änderungen sind bislang vorhanden:
- Apache Tika 1.17
- Solr now uses Log4J 2.11 . The log4j configuration is now in log4j2.xml rather than log4j.properties files.
- Add new atomic operation“add-distinct“ to add values in a multi valued field if not already present.
- IndexFetcher now fetches only those files (from master/leader) that are different. This differential fetching now speeds up recovery times when full index replication is needed
