** There are three lock schemes to access the table space. **
** **
** The TABLE_LOCK_AT_ENTRY_LEVEL scheme locks the access to the table **
** space in the entry data structure. It restricts the number of lock **
** operations needed to go through the table data structures. **
** **
** The TABLE_LOCK_AT_NODE_LEVEL scheme locks each data structure **
** before accessing it. It decreases concurrrency for workers **
** accessing commom parts of the table space. **
** **
** The TABLE_LOCK_AT_WRITE_LEVEL scheme is an hibrid scheme, it only **
** locks a table data structure when it is going to update it. **
** **
** The TABLE_LOCK_AT_WRITE_LEVEL is the default scheme. **
