doctrine-batch-processing

doctrine-batch-processing is a skill for Claude Code from dev-toolings/superpowers-symfony. It costs 29 tokens per session (445 once invoked), scanned A, original, MIT.

A Symfony guide for processing large amounts of data with Doctrine, Symfony's database mapping tool. It covers reading records in batches, saving changes safely, and clearing memory as work progresses.

In plain words
What is it for?
Use it for bulk updates, imports, exports, entity or schema changes, and improving database-heavy Symfony code while checking relations and avoiding repeated queries.
Why use it?
It helps prevent long-running jobs from using too much memory, making too many database queries, or accidentally loading excessive data.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

doctrine-batch-processing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Doctrine Batch Processing (Symfony)

Use when

  • Processing more rows than fit in memory: imports, exports, backfills.
  • A command or worker runs out of memory iterating over entities.
  • Updating or deleting many rows at once.
  • Inserting large volumes through Doctrine or DBAL.

Default workflow

  1. Measure the dataset size and the memory budget of the process.
  2. Stream reads with toIterable(), or paginate by id (id > :lastId) for very large tables.
  3. Flush and clear() every N items, and re-fetch anything needed after a clear.
  4. Use DQL UPDATE/DELETE or DBAL for bulk writes that need no hydration.
  5. Log memory usage and progress, and make the run resumable.

Guardrails

  • Never findAll() on a table that grows.
  • Entities loaded before a clear() are detached: do not modify or persist them.
  • Bulk DQL and DBAL skip lifecycle events and listeners. Check what relies on them.
  • On ORM 3, Query#iterate() and setSQLLogger() are gone: use toIterable() and a logging middleware.
  • Paginate by id rather than by offset: offsets get slower and skip rows when data moves.

Progressive disclosure

  • Use this file for execution posture and risk controls.
  • Open references when deep implementation details are needed.

Output contract

  • A batch loop with an explicit batch size and clear points.
  • The choice between ORM, DQL bulk and DBAL for each write, with the reason.
  • Memory measurements before and after on a realistic volume.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
