 # Rocksdb Change Log
+## Unreleased
+### New Features
+* Log CompactOnDeletionCollectorFactory window_size and deletion_trigger parameters in the info log file for troubleshooting purposes.
+
 ## 6.9.1 (04/09/2020)
 ### Bug Fixes
 * Fix wrong result being read from ingested file. May happen when a key in the file happen to be prefix of another key also in the file. The issue can further cause more data corruption. The issue exists with rocksdb >= 5.0.0 since DB::IngestExternalFile() was introduced.
