Symptom

The client gets an exception similar to: 
ReplyError: ERR max single record size exceeded

​
Diagnosis

An entry size exceeds the max record size limit which is 100Mb for “Free” and “Pay as you go” databases. You may reach this limit either by inserting a single huge value or appending many small values to an entry. This entry can be a String, List, Set, Hash etc. Read (GET, LRANGE, HMGET, ZRANGE etc) and delete (DEL, LPOP, HDEL, SREM etc) requests will not be affected.

​
Solution-1

You can split your data into smaller chunks and store them as separate entries with different keys.

​
Solution-2

You can upgrade your database to Pro as it has higher limits. Also you can submit quota increase request in the console or contact support@upstash.com about the options with higher max record size limit.
