# Limits

> Request size, rate limits, timeouts

Limits are enforced at the reverse proxy before the application.

## Request body size

| Request type                                         | Maximum   |
| ---------------------------------------------------- | --------- |
| Ingest (`POST /uploading/:upload_uuid/:entity_name`) | **32 MB** |
| Other requests                                       | **1 MB**  |

Exceeded → `413 Request Entity Too Large`. Split large datasets into multiple sequential packages.

## Rate limits and concurrency

For `/api/v1/` per client IP (egress):

| Parameter              | Value        |
| ---------------------- | ------------ |
| Average rate           | **30 req/s** |
| Burst                  | **50**       |
| Concurrent connections | **30**       |

Exceeded → `503 Service Temporarily Unavailable`.

## Timeouts

Maximum request time at the proxy — **600 seconds**.

## Recommendations

* Send large datasets in **packages**, not a single max-size payload
* Avoid unbounded **parallel** ingest requests
* Poll `GET /status` **periodically**, not as a continuous stream
* Access is allowed only from **whitelisted IPs** — list provided by support
