Resource exceeds maximum allowed size. Maximum allowed size is 16384 bytes

Question

Hi,

I get an error while creating a document that is above 16KB.

Exception: Microsoft.Azure.Documents.RequestEntityTooLargeException, message: {"Errors":["Resource exceeds maximum allowed size. Maximum allowed size is 16384 bytes

Is there some override that will allow me to get past it?

Thanks

Answer 1

I am unable to upload documents larger than 16kb. If I upload ~20KB, I get the following exception in the .NET client:

Microsoft.Azure.Documents.RequestEntityTooLargeException, message: {"Errors":["Resource exceeds maximum allowed size. Maximum allowed size is 16384 bytes. Actual size is 20081 bytes."]}

According to DocumentsDB Limits the "Maximum request size of document, attachment, stored procedure, trigger and UDF" is 16KB.

Am I understanding this correct that documents larger than 16KB is not supported? The reason I'm not certain is that the page says "Maximum request size of document", rather than "Maximum size of document".

Hi,

You are correct. Currently the size of the document is limited to 16 KB.

If you want to have the size increased in the future, please do provide us a feedback.

I've added it here:

http://feedback.azure.com/forums/263030-documentdb/suggestions/6339464-support-documents-larger-than-16kb

But what's is the rationale behind this? 16KB is tiny in terms of a single document in a document database.

Hi,

This limit as well as others are a pragmatic choice in the first Preview release to avoid unconstrained
use cases and patterns. We set these limits based on the telemetry data gathered from various 1st party consumer services that have been using DocumentDB for some time now. We looked at how many collections services were creating per unit, the average document size, the maximum document size, page count on the response feeds and so on.

However, these limits are not intrinsic limitations of the underlying service or technology.
We intend to change some of these limits based on usage driven telemetry as well as, your feedback.

Regards,

Mekh.

At the moment, DocumentDB document size is limited to 16KB. Check here for details. Or check this earlier forum post.

Or vote for this feedback item if you want larger document sizes.
