ERR max request size exceeded

Symptom

The client gets an exception similar to:

ReplyError: ERR max request size exceeded

Diagnosis

Your command exceeds the max request size which is 1Mb for “Free” and “Pay as you go” databases.

Solution-1

You can split your data into smaller chunks and send them in separate commands.

Solution-2

You can upgrade your database to Pro/Enterprise as it has higher limits. Also you can submit quota increase request in the console or you can contact [e-mail] about the options with higher max request size limit.

max-request-size-limit is about the size of a single request. Your data structure (like list, set) can exceed the max request size limit without any problem. If you try to load all elements in the list with a single request then it can throw the max-request-size-limit exception.
