>
> When querying table information for master status pages, currently method is
> using admin interfaces. For example, when list user tables, codes are as
> follows.
> Connection connection = master.getConnection();
> Admin admin = connection.getAdmin();
> try {
> tables = admin.listTables();
> } finally {
> admin.close();
> }
> But actually, we can get all user tables from master's memory.
> Using admin interfaces means using RPCs, which has a low efficiency.
