WordPress plugin · database maintenance
Your database is hauling gigabytes it will never use again.
WordPress reads a block of options into memory on every single request, and nothing tells you how big it has grown. Add transients that expired months ago, trash nobody emptied, and revisions of pages rewritten a dozen times, and the database gets heavier every week while backups take longer. Featherweight scans all of it, shows you the weight, and cleans only what is provably dead.

The problem
The bloat nobody budgeted for.
The heaviest thing on most WordPress sites is not a plugin, it is the data plugins leave behind. Autoloaded options are read into memory on every request, so a few megabytes there taxes every page view by every visitor, and nothing in wp-admin shows you the total. Documented cleanup reports show admin pages going from 8 seconds to under 2 after clearing autoload bloat alone. Underneath that sit transients that expired months ago, trash nobody emptied, and revision history nobody will ever read.
Then there is the background queue. Action Scheduler ships inside a number of plugins, it records every job it runs, and core cleanup never purges the failed ones, so those rows accumulate for the life of the site. If you run a store this is the single biggest win here, and public GitHub issues document those tables reaching tens of gigabytes on ordinary WooCommerce sites. If you do not run one, the queue cleaners simply find less to do and everything above still applies. None of it is misconfiguration, it is what a busy site does by default.
Starts safe
Dry-run by default
Every cleanup only reports what it would delete until you untick dry-run. Plus hard-coded guarantees: nothing younger than its retention, pending jobs sacred, and orders, products, customers and users never touched at all.
What it does
Featherweight, feature by feature.
The scan
One click: table sizes, queue rows by status (failed called out), total autoload weight, expired transients and sessions, trash and spam, and an honest “estimated reclaimable” figure.
Seven cleaners
Queue complete/canceled, queue failed, expired transients, expired sessions, trash, spam, old revisions, each independently toggleable with its own retention window.
Autoload advisor
The options loaded into memory on every page view, sorted by weight and identified by plugin where possible, with a functionally-safe “stop autoloading” that's one-click reversible. Core-critical options never offered.
Hard safety rules
Dry-run default. Nothing younger than its retention. Pending and in-process jobs sacred. And regardless of any setting: orders, products, customers and users are never touched.
Never hangs your site
Deletes run in bounded batches inside a 15-second budget; anything left schedules its own continuation a minute later. Big cleanups happen in polite slices.
Set-and-forget weekly
Pick a quiet hour; Featherweight runs the enabled cleaners weekly and (if you want) emails a “reclaimed X this week” summary. Full history of every run, kept in one non-autoloaded option.
Seven cleaners, each with a never-touch list
Every cleaner deletes only what is provably dead, and each has hard-coded rows it will never touch, regardless of settings.
| Cleaner | Deletes | Never touches | Default |
|---|---|---|---|
| Queue: done | Complete/canceled background actions + their logs | Pending & in-process jobs | On · 7-day retention |
| Queue: failed | Failed actions + logs, the rows core keeps forever | Recent failures (kept for debugging) | On · 30-day retention |
| Transients | Expired only (site + network scope) | Live caches, no-expiry transients | On |
| Sessions | Expired WooCommerce sessions + legacy leftovers | Active carts & sessions | On |
| Trash / spam | Already-trashed posts, spam comments past retention | Anything published or pending | On · 30-day retention |
| Revisions | Revisions past retention | Recent revisions | Off · 60-day retention |
| OPTIMIZE pass | Rebuilds cleaned tables to reclaim disk | Nothing (it briefly locks tables) | Off |

Where it fits
Honest comparisons, category by category.
No named-competitor trash talk, just what each category of tool is good at, and where this plugin earns its keep.
vs. generic DB cleaners
Generic cleaners do the classic checklist well, revisions, drafts, trash, spam, expired transients, and Featherweight covers that same ground. The gap is what they leave behind: the background queue, and the memory tax on every page view.
- Status-aware Action Scheduler retention, including failed actions core never purges (one public report: 55 GB, 137M rows).
- Expired sessions and the transients core's own cleanup tool misses on a store.
- Autoload advisory with safe, reversible undo. Running both cleaners is safe, dead rows delete once.
vs. manual SQL
Hand-run DELETEs work, and risk orphaned log rows, truncated live-queue tables, transient ghosts under object caches, and one enormous locking DELETE. Featherweight's cleaners are those lessons, written down as code.
- Dry-run is the preview from the same code that deletes.
- 5,000-row batches inside a ~15-second budget, with scheduled continuation.
- Manual SQL is still right for one-off emergencies, schema work, and forensics.
vs. hosting optimizers
Hosts optimize infrastructure, PHP, caches, CDN, MySQL config. Featherweight optimizes the application's data: which rows are dead is an application-level judgment a host can't make.
- Good hosting masks data bloat, a strong server delivers a bloated database quickly.
- The bloat still bites: backups stretch, migrations crawl, restores take hours.
- Complementary in both directions, keep the good host, clean the data.

FAQ
Straight answers.
Can this delete my orders or customers?
No, categorically. No cleaner queries those tables. The rules are hard-coded, not settings.
Is deleting background-queue rows actually safe?
Yes, with guards: only complete, canceled, or failed rows past their retention window are touched. Pending and in-process jobs are never touched.
Why keep failed actions longer than completed ones?
Recent failures are diagnostic gold. The default keeps 30 days of them while ending the keep-forever accumulation.
I ran a cleanup and my database files didn't shrink. Bug?
Expected, InnoDB reuses freed space internally. That's what the optional OPTIMIZE pass is for (off by default, because it briefly locks tables).
Is “stop autoloading” going to break a plugin?
Functionally, no: the option still exists and get_option() still works, WordPress just stops preloading it on every page. One-click revert, and core-critical options are never offered.
Do I need WooCommerce?
No. The queue, transient, trash, and autoload cleaners help any WordPress site. The WooCommerce-specific cleaners simply stand down when WC is absent.
How is this different from the cleaner plugin I already run?
Possibly complementary. Check whether yours purges failed queue actions, expired WooCommerce sessions, and offers autoload advisory with undo, that trio is the gap.
My site uses an object cache, do expired transients even matter?
With a persistent object cache the scan will show near-zero there, and queue rows, sessions, and autoload weight remain fully relevant.
What does it cost to run?
A handful of information_schema and COUNT queries on demand; cleanups in 5,000-row batches inside a 15-second budget. It adds no tables and autoloads nothing of its own.
