Random access to small global state

[Sebastian]

Hi,

I'm planning to work on a streaming recommender in Flink, and one 
problem that I have is that the algorithm needs random access to a small 
global state (say a million counts). It should be ok if there is some 
inconsistency in the state (e.g., delay in seeing updates).

Does anyone here have experience with such things? I'm thinking of 
connecting Flink to a lighweight in-memory key-value store such as 
memcache for that.

Best,
Sebastian
