## What changes were proposed in this pull request? Context: https://github.com/apache/ozone/pull/8787#discussion_r2212829117 `-1` is a valid value for max_open_files option, along with `0` > max_open_files – RocksDB keeps all file descriptors in a table cache. If number of file descriptors exceeds max_open_files, some files are evicted from table cache and their file descriptors closed. This means that every read must go through the table cache to lookup the file needed. Set max_open_files to -1 to always keep all files open, which avoids expensive table cache calls. https://github.com/facebook/rocksdb/wiki/RocksDB-Tuning-Guide#tuning-other-options ## What is the link to the Apache JIRA https://issues.apache.org/jira/browse/HDDS-13473 ## How was this patch tested? - Existing tests -- This is an automated message from the Apache Git Service.
