batch_processing_with_find_each

📦 Batch Processing with find_each

Process large datasets in batches to avoid memory bloat. find_each retrieves records in batches and yields them one by one.

# Process 1,000 users at a time without loading all at once
User.where(needs_reindex: true).find_each(batch_size: 1000) do |user|
  user.reindex_profile
end
