Hi all,
Is ShortCircuit read faster than legacy read which goes through data nodes?
I have evaluated SCR and legacy local read on both HDD and NVMe SSD.
However, I have not seen any results that SCR is faster than legacy.
Rather, SCR was slower than legacy when using NVMe SSDs because of the

Interesting benchmark. Thank you, Daegyu.
Can you try a larger file too? Like 128mb or 1gb? HDFS is not optimized for
smaller files.
What did you use for benchmark?

But these are great questions.
Re: benchmarks for SCR:
I believe yes. In fact, I found a benchmark running Accumulo and HBase on
HDFS
