Description
Currently we implements a max cache size on the server side. When cache is full, it stops taking new values: https://github.com/XiangpengHao/datafusion-cache/blob/main/src/liquid_parquet/src/cache/mod.rs#L312
We should implement a cache replacement algorithm that will evict the least recently accessed columns to make space for new entries.
