Early caching unexpected behavior: Altered keys and skipping mem backend

[sohang123]

We were originally using simple caching with both a redis and memory (prefix mem:) backend. After switching to using cache.early 1. the keys were altered from e.g "2024-08-19T19:26:04:xyz" to "2024-08-19T19:26:04:early:v2:xyz". Also nothing was put into in memory cache. Instead there was a duplicate in redis. In redis we saw bot the "2024-08-19T19:26:04:early:v2:xyz" and "2024-08-19T19:26:04:early:v2:mem:xyz" keys. Anyone have any tips on how to work with the early caching so that we can have the original keys and both in memory and redis caching working?
