  #{Rails.env}
  shard_#{Rails.env}
  shard2_#{Rails.env}
)
HeartSeed::DbSeed.import_all_with_shards(shard_names: SHARD_NAMES)

Insert Mode

MODE=(bulk|active_record|update) bundle exec rake db:seed

• bulk(default): using bulk insert. (delete_all and BULK INSERT)
• active_record: import with ActiveRecord. (delete_all and create!)
• update: import with ActiveRecord. (if exists same record, update!, otherwise create!)
