Workers - Increased blob size limits in Workers Analytics Engine

We’ve increased the total allowed size of blob fields on data points written to Workers Analytics Engine from 5 KB to 16 KB . 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 . JavaScript export default { async fetch ( request , env ) { env . analyticsDataset . writeDataPoint ( { // The sum of all of the blob's sizes can now be 16 KB blobs : [ // The URL of the request to the Worker request . url , // Some metadata about your application you'd like to store JSON . stringify ( metadata ) , // The version of your Worker this datapoint was collected from env . versionMetadata . tag , ] , indexes : [ "sample-index" ] , } ) ; }, }; TypeScript export default { async fetch ( request , env ) { env . analyticsDataset . writeDataPoint ( { // The sum of all of the blob's sizes can now be 16 KB blobs : [ // The URL of the request to the Worker request . url , // Some metadata about your application you'd like to store JSON . stringify ( metadata ) , // The version of your Worker this datapoint was collected from env . versionMetadata . tag , ] , indexes : [ "sample-index" ] , } ) ; } }
