Multi_get throws error

continue to get multi_get and node is evicted

Whether multi_get could cause node eviction

It shouldn't, but you may be abusing it. Can you provide more information?

Yeah, that's why.
How much heap does the node have? What is the mget query you are running.

Hi please let me know whether mget can cause OOM or default mapping will cause OOM

Can you post your query correctly formatted rather than the above, it's really hard to read.
