In Catalyst Cache, the maximum length of a cache value is 16,000 characters. A cache item is a key-value pair stored in a cache segment, with a keyname, a value and an expiration time in hours. The Insert and Update Key-Value APIs also list 16,000 characters as the maximum size of `cache_value`. You can see the total size of each segment under Cache in DevOps Metrics.

Refer to the [Cache Key Concepts help page](https://docs.catalyst.zoho.com/en/cloud-scale/help/cache/key-concepts/) and the [Insert Key-Value in Cache Segment API page](https://docs.catalyst.zoho.com/en/api/code-reference/cloud-scale/cache/insert-key-value-in-segment/#InsertKeyValueinCacheSegment) for details.
