We’ve increased the total allowed size of `blob` fields per request from **5 KB to 16 KB** in the Workers Analytics Engine.

This change gives you more flexibility when logging rich observability data — such as base64-encoded payloads, AI inference traces, or custom metadata — without hitting request size limits.

You can find full details on limits for queries, filters, payloads, and more [here in the Workers Analytics Engine limits documentation](https://developers.cloudflare.com/analytics/analytics-engine/limits/).
