Process large datasets with Doctrine (ORM 3 toIterable, flush+clear, bulk DQL) and memory management.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file 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. …

How to install
mdr add dev-toolings/superpowers-symfony/doctrine-batch-processing@sha256:19ad9e5dd0daeb9fThe line at the top of this page pins the label git:20261005.6632a97, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
