Your database's daily limit: alerts, paused writes and how to write less

Who this is for: anyone with a site or app on YaDominios Cloud that uses a database, and anyone who builds it — a person or an AI.

Limits by plan

Plan	Rows written per day	Rows read per day
Nébula	50,000	20 million
Órbita	150,000	50 million
Galaxia	500,000	200 million
Cosmos	1,500,000	500 million

The day is counted in Coordinated Universal Time (UTC). A typical business uses a small fraction of its limit: a store selling a hundred products a day writes a few thousand rows.

What happens at the limit

1. At 80% you get an email with your usage and your limit.
2. At 100% of writes we pause your site's writes until midnight (UTC). Your site stays up: it can be viewed, browsed and read from its database as usual. Anything that tries to save new data gets a clear error saying writes are paused. You get another email.
3. At midnight everything resumes on its own. Nothing was deleted.
4. Reads are never paused: if you go over your read limit, we only alert you.

Where to see it

In the panel, on your site card, the Database writes today bar shows your usage and your limit. If writes are paused, the card says so.

Why an app writes so much (and how to write less)

• INSERT OR REPLACE on rows that didn't change. It doesn't update: it deletes the row and inserts it again, and if other tables depend on it through cascading deletes or triggers, each replace can write hundreds of rows. Use INSERT … ON CONFLICT(id) DO UPDATE SET … WHERE with a condition that something changed.
• Syncs that upload everything. Upload only what changed since last time, with a timestamp per device.
• Per-visit counters. A visit shouldn't write to the database: no counters, no guest sessions, no "last seen".
• Extra indexes. Every index counts as one more write for each row that changes. Keep only the ones a real query uses.

A simple test: sync twice in a row without changing anything. The second time should write zero rows.

If you need more

If your business really writes more than your limit, contact Support: we'll raise your limit the same day, and if writes were paused, they resume right away.
