/* bdb based storage translator - named as 'bdb' translator
- *
- *
+ *
+ *
* There can be only two modes for files existing on bdb translator:
- * 1. DIRECTORY - directories are stored by bdb as regular directories on background
- * file-system. directories also have an entry in the ns_db.db of their parent directory.
- * 2. REGULAR FILE - regular files are stored as records in the storage_db.db present in
- * the directory. regular files also have an entry in ns_db.db
+ * 1. DIRECTORY - directories are stored by bdb as regular directories on
+ * back-end file-system. directories also have an entry in the ns_db.db of
+ * their parent directory.
+ * 2. REGULAR FILE - regular files are stored as records in the storage_db.db
+ * present in the directory. regular files also have an entry in ns_db.db
*
- * Internally bdb has a maximum of three different types of logical files associated with
- * each directory:
- * 1. storage_db.db - storage database, used to store the data corresponding to regular
- * files in the form of key/value pair. file-name is the 'key' and data
- * is 'value'.
- * 2. directory (all subdirectories) - any subdirectory will have a regular directory entry.
