What's New in Apache Solr
New features and functional updates for Solr are introduced in Cloudera Runtime 7.3.2, its service packs, and cumulative hotfixes.
Cloudera Runtime 7.3.2.10000:
- Solr supports incremental backup and restore
- Solr now supports incremental backup and restore through the Collections REST API.
Incremental backups optimize storage and reduce data transfer by backing up only the
changes since the previous backup. You can create incremental backups, restore
specific backup versions, and list available backups by using the Collections REST API
BACKUP, RESTORE, and
LISTBACKUP commands. Incremental backup is the default behavior
for API-based backups. To create a traditional non-incremental backup through the API,
set the incremental=false parameter on your backup request.
Backups created through snapshots by using the
solrctlutility remain non-incremental.
Cloudera Runtime 7.3.2:
- Solr JDK 17 upgrade
- Solr supports JDK 17 starting with the 7.3.2 release. Upgrade to JDK 17 to gain improved performance, increased security, modern language features, and long-term support, ensuring your application remains competitive and maintainable.
