What's new in Cloudera Runtime 7.1.9 SP2 CHF 4
New features and functional updates for Runtime components are introduced in Cloudera Runtime 7.1.9 SP2 CHF 4.
Platform
- New platform support
- RHEL 9.8 is now supported starting from 7.1.9 SP2 CHF 4.
Ozone
- Performance optimization for Ozone metadata operations
- Ozone reduces unnecessary RocksDB iterator seeks during metadata reads and listings. Operations that start at a specific key or continuation marker can now position the iterator directly, avoiding an initial seek to the beginning of the table or prefix. This can reduce latency for listKeys, S3 ListObjects, OzoneFS listStatus, and paginated snapshot listings, particularly when the skipped seek would traverse many deletion markers (tombstones) that RocksDB has not yet compacted. The performance benefit depends on the workload and database compaction state.
