Firstly, I don't think db lock on the same database is not a distribute
solution, although it may not be the best solution in most cases.
Then, let's skip the distribute lock.
The case that database partition is only required for some special tables
exists, which means all other tables being in a default or primary database,
sql with no tables is the same. `default-data-source-name` is worked for the
case on other tables, if support for no table is added, the function of
`default-data-source-name` can be better.
