How is read and write cache shared?

Let's say I have 1 GB cache and use this for read and writes. How are the 1 GB shared for cached reads and cached writes?

If the cache strategy is Read/Write, all reads and writes will be cached. Cache content will be replaced by specified algorithm when cache space is full.

Just to clarify, does that mean that memory allocation would follow usage? (e.g. a system that does 4 times as much reading as writing would likely have the cache split 80/20 for read/write data). Or do other factors come into play (e.g. a large write defer setting prioritising write data retention).

Yes. However in future versions, we might allow users to divide read/write cache area.
