Increased database sync sizes and improved error handling

Our database import feature lets you import and update people from your MySQL or Postgres database. We've recently increased the capacity of imports from 2 million to 10 million rows, making it easier to support large audiences! As a part of this update, we also exposed error files for each sync interval; these files show which rows failed to import, which can help you refine your query or tables and provides a path to import or update people represented by errored rows.
