Hi Igniters, I have been looking in to the per-entry overhead for Ignite cache entries and have a couple of questions.
1. Does each GridCacheMapEntry require a reference to GridCacheContext<?, ?> or could this field be removed/optimized in some way? Is the GridCacheContext instance the same for every entry in a particular cache? 2. Is the GridCacheMapEntry extras field (a reference to GridCacheEntryExtras) often/usually null? If so, could we find a clever way to remove this field and save a further 8 bytes? The reason for asking is that I am looking at a use-case where object sizes are very small, but the number of objects is very large, and therefore the overhead is substantial. In this particular case, the overhead is 70-75% of the consumed memory. I look forward to hearing your thoughts. Regards Mike -- Sent from: http://apache-ignite-developers.2346864.n4.nabble.com/
