RocksDB.getProperty介绍

[英]DB implementations can export properties about their state via this method. If "property" is a valid property understood by this DB implementation, fills "*value" with its current value and returns true. Otherwise returns false.

Valid property names include:

• "rocksdb.num-files-at-level<N>" - return the number of files at level <N>, where <N> is an ASCII representation of a level number (e.g. "0").
• "rocksdb.stats" - returns a multi-line string that describes statistics about the internal operation of the DB.
• "rocksdb.sstables" - returns a multi-line string that describes all of the sstables that make up the db contents.
  [中]DB实现可以通过此方法导出有关其状态的属性。如果“property”是此DB实现可以理解的有效属性，则用其当前值填充“*value”，并返回true。否则返回false。
  有效的财产名称包括：
  *“rocksdb.num级别<N>的文件数”-返回级别<N>的文件数，<N>是级别号的ASCII表示形式（例如“0”）。
  *“rocksdb.stats”-返回一个多行字符串，描述数据库内部操作的统计信息。
  *“rocksdb.sstables”-返回一个多行字符串，该字符串描述构成db内容的所有sstables。
