In RocksDB 4.3, we added a new set of features that makes managing RocksDB options easier. Specifically:
|
|
|
|
* **Persisting Options Automatically**: Each RocksDB database will now automatically persist its current set of options into an INI file on every successful call of DB::Open(), SetOptions(), and CreateColumnFamily() / DropColumnFamily().
|
|
|
|
|
|
|
|
* **Load Options from File**: We added [LoadLatestOptions() / LoadOptionsFromFile()](https://github.com/facebook/rocksdb/blob/4.3.fb/include/rocksdb/utilities/options_util.h#L48-L58) that enables developers to construct RocksDB options object from an options file.
|
|
|
|
|
|
|
|
* **Sanity Check Options**: We added [CheckOptionsCompatibility](https://github.com/facebook/rocksdb/blob/4.3.fb/include/rocksdb/utilities/options_util.h#L64-L77) that performs compatibility check on two sets of RocksDB options.
