> Steps to be able to reproduce it :
>  - have a heap of 1Gb
>  - have a saved key cache without the SSTables
> When looking at KeyCacheSerializer.serialize : it always writes a Boolean
> When looking at KeyCacheSerializer.deserialize : no Boolean is read if SSTable is missing...
> In case of a promoted index, RowIndexEntry.serializer.skip(...) should be called rather
than RowIndexEntry.serializer.skipPromotedIndex(...) (again for symmetry between serialization/deserialization)
> Attached is a proposed patch
