/**
 * What is a current snapshot?
 * - it is the latest snapshot with 'current' status if exists;
 * - otherwise it is any latest snapshot (can be 'old' or 'new');
 * - if no snapshot records found (maybe corrupted DB?): create and initialize new snapshot.
 *
 * Update from previous versions (without snapshots, when no snapshots table exists before):
 * - create new snapshot with ID = 1 and assign this snapshot ID to all existing content items.
 *
 * When new snapshot added:
 * - add all published items from selected post categories and/or pages with initial status ACTION4_ANALYZING_INITIAL;
 * - add the rest of published items with initial out-of-scope status ACTION4_OUT_OF_SCOPE_INITIAL.
 *
 * Then run content audit for newly created snapshot.
 *
 * Finally, when all items updated:
 * - calculate traffic median;
 * - update status of snapshot from 'new' to 'current' (and previous 'current' to 'old').
 *
 * How to determine, do we need to update items or not?
 * - if we have a snapshot with 'new' status - then we need to run update. Otherwise - no update needed.
