heavy-db-index-operation

Generate background migration modules for creating, dropping, or renaming database indexes on large tables using the Explorer.Migrator.HeavyDbIndexOperation framework. Automatically updates the BackgroundMigrations cache module with proper tracking. These migrations run in the background with progress tracking and dependency management. Use this skill for requests on creating background migrations to delete / create / rename indexes on large tables (logs, internal_transactions, token_transfers, addresses, transactions, blocks, etc.) to avoid blocking the database.
