Once T173513: Create a database on the wikireplica servers called "datasets_p" is finished, we'll need some documentation about how to maintain table between the 2+ replica hosts. We'll also need some user-documentation to explain where to go to request a new table be imported into "datasets_p". (c.f. basically, file a task and tag T173512: Create a phabricator project called "wikireplica-datasets").
In the short term, the process could be something like "run mysqlimport once for each host" and "run 'SELECT COUNT(*) FROM ...' on each host" to check that the table loads completed successfully.
