# Ninja Forms - Large Cache Fix

Resolves the issue of large forms crashing on publish due to cache size.

## Methodology

This fix uses the `pre_option_{$option}` and `pre_update_option_{$option}` filters as as a sort of man-in-the-middle solution. Option updates are intercepted on update and "chunked" into multiple options, storing a reference to the created chunks in an additional option. Inversely, option requests are intercepted and joined back together before they are retuned.

## Example

Form Length: 515,988 characters

Chunk Size: 65,535 (TEXT)

Number of Chunks: 8

Number of Options: 10 (chunks + 2)

## MySQL String Type Reference

| MEDIUMTEXT | 16,777,215 (224−1) bytes = 16 MiB |
