Summary: Add GetThreadList API, which allows developer to track the status of each process. Currently, calling GetThreadList will only get the list of background threads in RocksDB with their thread-id and thread-type (priority) set. Will add more support on this in the later diffs. ThreadStatus currently has the following properties: // An unique ID for the thread. const uint64_t thread_id; // The type of the thread, it could be ROCKSDB_HIGH_PRIORITY, // ROCKSDB_LOW_PRIORITY, and USER_THREAD const ThreadType thread_type; // The name of the DB instance where the thread is currently // involved with. It would be set to empty string if the thread // does not involve in any DB operation. const std::string db_name; // The name of the column family where the thread is currently // It would be set to empty string if the thread does not involve // in any column family. const std::string cf_name; // The event that the current thread is involved. // It would be set to empty string if the information about event // is not currently available.
