各參數說明：
tokudb_cache_size
默認情況下，TokuDB分配50%的系統物理內存。
tokudb_data_dir
指定TokuDB數據的存儲位置。默認為空，使用datadir定義的路徑。
tokudb_log_dir
指定TokuDB日志的存儲位置。默認為空，使用datadir定義的路徑。
tokudb_tmp_dir
TokuDB批量導入數據時，臨時文件的存儲位置。TokuDB在使用LOAD DATA導入數據的時候會通過臨時表(可能會很大)來完成。
默認為空，使用datadir定義的路徑。
tokudb_pk_insert_mode
主鍵寫入的模式，只有值為2時，才支持RBR。
