HI there.

I will make some feed system and i wanna realtime sorting for user like 
count.

Author -- Follow --> Author.
Author -- Write ---> Article.
Author -- Like --> Article 

When i Quering like "out('Follow').out('Write').in('Like').size()" is too 
slow.
So i modify Article to had likeCount.

query chaged to 
SELECT out('Follow').out('Write').likeCount FROM Author where name = 
'author_1' ORDER by likeCount DESC.
This query is faster than last query.

But I need more faster to realtime sorting.

Can I store all graph vertex and edge in memory with distributed Graph 
Database?
Include hardware write.

I found this(OrientDB & 
Hazelcast, https://www.youtube.com/watch?v=FfcLWgLcka0)
It explaned distributed, right? I cannot find where is In-memory.
