ERR max field size exceeded

​

Symptom

The client gets an exception similar to:

ReplyError: ERR max field size exceeded. Limit: X bytes, Actual: Z bytes

​

Diagnosis

Size of a HASH field in the request exceeds the max field size limit, which is 32Kb.

​

Solution

This is a hardcoded limit and cannot be configured per database. You should reduce the field sizes in HASH entries.
