The client gets an exception similar to:
ReplyError: ERR max single record size exceeded
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 (
ZRANGE etc) and
SREM etc) requests will not be affected.
You can split your data into smaller chunks and store them as seperate entries with different keys.
You can upgrade your database to Pro/Enterprise as it has higher limits. Also you can submit quota increase request in the console or contact email@example.com about the options with higher max record size limit.
