Lisheng Sun commented on HDFS-15409:
------------------------------------
yeah, it should be that.
My idea is also to learn from the way of hbase to split the region.
I think this strategy should be both complicated and interesting.
So we should also think about it, it’s best to organize our ideas on a doc.
> Optimization Strategy for choosing ShortCircuitCache
> -----------------------------------------------------

> Key: HDFS-15409
> URL: https://issues.apache.org/jira/browse/HDFS-15409
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Lisheng Sun
> Assignee: Lisheng Sun
> Priority: Major
>
> When clientShortCircuitNum is 10, the probability of falling into each
> ShortCircuitCache is the same, while the probability of other
> clientShortCircuitNum is different.
> For example if clientShortCircuitNum is 3, when a lot of blockids of SSR are
> ***1, ***4, ***7， this situation will fall into a ShortCircuitCache.
> Since the real environment blockid is completely unpredictable, i think it is
> need to design a strategy which is allocated to a specific ShortCircuitCache.
> This should improve performance even more.
